Best Tanning Lotion Buying Guide 2017

Whether you are a fan of sitting in the sun but want a bit of a protection, have sensitive skin and need an organic product or like to get the best results from indoor tanning, there is the best tanning lotion or cream perfectly suited for you.

Many people love the look of bronzed derma and it improves their self-esteem and confidence. Others need to spend a lot of time outside and must protect their derma from the effect of the sun. All of these variations of products we will be glimpsing at here.

Tanning lotion

There is a wide range of the best tanning lotions that contain ingredients, formulas and features that work differently with the skin. Therefore understanding what these benefits are can help you ensure you are getting the best lotion for your derma.

One important thing to look for when choose a tanning lotion is moisturiser. It has been shown that moist skins tan easier than dry skin does and also retains the tan for longer.

Moisturisers also help to replenish the skin cells and protect them against damage. Common ingredients in moisturisers include hemp seed oil, silicon, shea butter and vitamin E.

Another important ingredient to watch out for is aloe. The aloe vera plant has natural cooling properties as well as healing minor burns such as sunburn so if a tanning lotion contains this, it can help if you get too much tan.

This is particularly advisable for someone who has never used indoor tanning before or hasn’t used it for a long time.

There are some other elements in tanning lotions that have benefits for different people.

One such ingredient is a bronzer. This is a self-tanning ingredient that naturally darkens derma so added with tanning can allow for a darker tan in a short time. Bronzers can be things like DHA, vitamin A and beta-carotene and naturally darken the skin’s pigmentation.

Similarly, consider the mix of accelerators and maximizers. These help to build the base of tan and to increase the speed, which skin tans using amino acids such as tyrosine and psoralen as well as vitamin A to help the body create more melanin.

The more melanin, the darker the tan. Accelerators also have moisturiser in them so this stop dermis from drying out.

Finally look for tanning lotions that have a tingle. This is a chemical reaction in the dermis that increases the blood flow, which in turn speeds up the natural repair process in the skin. This means you tan quicker, with less damage caused to the skin.

Tanning Oil

Tanning oil is designed to work in a similar way to tanning lotion but uses natural oils with the chemical ingredients to make the skin tan easier. Common ingredients include coconut oil, aloe vera sesame oil and lanolin as well as vitamins and chemicals.

These generally result in the dermis being moisturised and also gives the derma a shiny and glossy look. Tanning oil works by increasing the tan on the dermis from the UV rays of the sun.

This means there is no UV protection in most of the products though there are some that have a low amount in, usually no more than SPF4.

Because of the speed that it works, tanning oil is not recommended for people that have fair derma or who are very sensitive to the sun’s rays.

It is also best to use when you already have a light suntan, otherwise there is an increased risk of burning. Tanning oil is not baby oil – baby oil should not be used for this purpose as it can lead to very bad sunburn.

[su_button url="#" target="blank" background="#ee4a03" size="12" wide="yes" center="yes" radius="0" icon="icon: arrow-circle-right" rel="nofollow" title=""]Check The Best Price[/su_button]

Sunscreen

The aim of sunscreen is simple – to stop the ultraviolent (UV) radiation from getting to the skin. Both UVA and UVB radiation leads to damage to the skin including prematurely aging it and can also increase the risk of cancers.

UVB is the causer of sunburn while UVA penetrates deeper into the skin and causes wrinkling, sagging and other light induced aging (often referred to as photoaging).

The two together increase the carcinogenic effects of the UVB and are being seen as a chief cause of some types of cancer.

Sunscreen is measured in SPF, which means Sun Protection Factor. A sunscreen with an SPF of 15 or higher does a great job of stopping the UVB radiation from damaging the skin.

It works like this; if unprotected body takes 20 minutes in the sun to go red, then by using SPF15 this means it would take 15 times longer to have the same effect – around five hours instead.

Another view of SPF is that it filters out the rays. The higher the number, the more rays it protects against. So for example, SPF 15 keeps out around 93% of the UVB radiation while SPF 30 keeps out around 97% and SPF 50 manages to exclude around 98% of the harmful rays.

This is relevant for everyone but especially for those with a history of cancer or who are particularly sensitive to the sun’s light.

The main downside with sunscreen is that it does need to be reapplied to maintain effectiveness. Generally, it is recommended to reapply the product every two hours to keep the sunscreen working to its maximum.

Who should use and what type?

Regardless of age and exposure to sunlight, everyone should use sunscreen when they are exposed to periods of sunlight.  This is especially important for people who work outside for most of the day.

It is also recommended that children under six months old be not exposed to the sun’s rays at all, as their body is extremely sensitive to the radiation and also to the chemicals in sunscreens. Clothing and shade are the best ways to protect the youngest children.

There are many products that have a small amount of SPF included in them and these may be okay for short trips out in the sunshine.

Many after-shave lotions and moisturisers have an in-built SPF factor but it will be a low number and cannot do the job of a proper sunscreen.

There are also some water resistant sunscreens that are great if you are at the beach and going in and out of the water without washing off your body.

These water resistant variations can be great if you are playing sports on a hot day as they won’t drip and run when you sweat the way normal sunscreens do. However, they may not be suitable for every day use as tend to be stickier and also don’t work well with makeup.

[su_youtube_advanced url="https://www.youtube.com/watch?v=-185_opq6aU" width="700" controls="no" autohide="yes" showinfo="no" rel="no"]

How much to use?

The general advice is that you need around a shot glass full of sunscreen to apply an effective layer – around 1 ounce.  Studies have shown that a lot of people use only around a quarter of this so they aren’t getting the full benefits of the SPF.

During the average day at the beach, one person should use between one-quarter and one-half of an 8oz. bottle, being applied 30 minutes before exposure starts and reapplied every two hours.

EltaMD SPF 50 UV Sport Waterproof Sunscreen, 3 Fluid Ounce	50	3oz	4.7 / 5	$$$

Sunscreen for Sensitive Skin

While the importance of sunscreen is clear, if you have sensitive body then the normal products may cause as many problems as they solve due to their irritation of the body. However, the Food and Drug Administration (FDA) have come up with some tips about what types of sunscreen ingredients will work for different types of skins.

Children

As mentioned before, children under 6 months old should not have sunscreen applied to them but for older children, sunscreens that contain zinc oxide and titanium dioxide have been shown to provoke less skin reactions.

Often sunscreens for kids come in bright colours and fancy packaging to convince the children to use them and this can be a good tactic while spray sunscreens can be an easy option.

However, it is recommended not to spray them directly onto children’s faces but put onto hands then onto faces to avoid problems.

Allergies and acne

If you are very prone to allergies or suffer with body conditions such as acne or rosacea than keep away from products that have preservatives in them as well as any that are fragranced. Also avoid anything containing PABA or oxybenzone as these are the most often shown to cause body reactions.

For those with conditions like acne, also avoid any products that have alcohol in them, though some gel based products containing alcohol have been found by some people to be less irritant.

Avoid ‘cream’ as these will make your skin even greasier unless you are using topical acne medication, in which case a light lotion or cream may combat the dryness caused by the medication.

Older people

Older people will have accumulated radiation exposure over the course of their years but using sunscreen is still important.  There is no age limit to the development of cancers and the sun can still have an aging effect on older skin.  Spray sunscreens can be a good bet for people with decreased mobility who cannot manage to apply a lotion to awkward spots.

Organic Sunscreens

Some people prefer organic products for a range of reasons; whether because it is what they believe in or they find that the lack of chemicals is beneficial to their body. Whatever the reason, there are plenty of sunscreens and sun protection products available that are organic.

One of the main names in this area is Badger, who have produced a range of sunscreens including a sports version, baby and kids products and even a face stick.

They are made from organic products, are sold at a reasonable price and offer a good level of SPF.  They also produce an after sun balm that is great to soothe the body after sunshine exposure.

[su_button url="#" target="blank" background="#ee4a03" size="12" wide="yes" center="yes" radius="0" icon="icon: arrow-circle-right" rel="nofollow" title=""]Check The Best Price[/su_button]

Lip Protection

If you have ever seen sports people with strange colors lips and wondered what they are doing, it is likely that they are using some type of lip protection.

This is because the skin on lips is particularly sensitive and can easily burn or get blisters on it that will be very painful and even lead to an infection.  For this reason, there are whole ranges of special lip protection products.

These products comes in a range of different types but the most common, and perhaps easiest to use, is one that look like a lip balm or lipstick and is applied in a similar way.

There are some that are water-resistant that can be used when swimming without constantly reapplying, though they will need to be replied similarly to sunscreen.

Some variations also use natural ingredients such as mint or berry flavouring to help mask the smell when it is so close to your noise.

After sun

After sun products work in tandem with sunscreens and are a great product to help combat the damage caused by the UVA rays – the type that sunscreens don’t combat.

These are the rays that age skin and damage cells and while after sun cannot stop this, it can help ease some of the damage this does.

The other main job that an after sun product does is helps to rehydrate the body. Sunshine dries out the body and while some sunscreens have moisturisers in them, it never hurts to add extra moisturisation and many after sun products are idea for this.

Some also feature ingredients such as chamomile and calendula that are great for reducing redness in the skin while those containing vegetable oils and shea butter can help to nourish the skin and avoid it peeling.

Therefore, after sun has a range of benefits that mean it is always worth applying after a day in the sunshine, regardless of what type of product you have used during the day.

Best VR Technology Sentinel CCR Review 2017

Best VR Technology Sentinel has realized that budget is a concern for customers. Now it is possible to order a standard Sentinel LSS (Life Support System) and upgrade the system as your budget allows.

The standard model does not have a CO2 monitor gauge, off-board gas blocks, or breathing hose covers, but is equipped standard with a BOV, on-board decompression, and a back plate.

This device – Optocons Complete is equipped with BOV, Deco software, Wing and Harness, 2 liter cylinders & constant electronics with backup display.

If you are looking for a Sentinel rebreather, then you can choose from their different packages with the necessary upgrades.

Choosing a Rebreather: Why Sentinel?

There are many quality rebreathers available with proper safety measures, but they all have different features. What’s important is to find the features which suit you most, not what someone else recommends.

If you need help figuring it all out, check for a retailer where you can easily compare all the possible units, then narrow your selection down to the unit that you want.

Already know what you want? Browse the units listed by manufacturer below. VR Technology’s has all the unique features and all the units you want in it, and surely will meet your all needs.

Unlike traditional design, this device includes a single back-mounted counterlung. This means you are once again equipped with a clear chest for stages, cameras and just squeezing through tight gaps.

Both a diver (with vibrating alarm) and buddy HUD mean that everyone is getting information of the state of your device, which is an useful feature when team diving. A passive back-up display provides an alternative source for monitoring PO2 in the loop.

[su_button url="#" target="blank" background="#ee4a03" size="12" wide="yes" center="yes" radius="0" icon="icon: arrow-circle-right" rel="nofollow" title=""]Check The Best Price[/su_button]

Some Features:

Let’s see how the features of the VR Technology make it unique from the others. Some of the unique features are:

• It is an electronics-driven, fully closed circuit PO2 design (eCCR) that provides a smart and easy to use life-support system (LSS)
• It has a unique, single 4.8 liter back-mounted counterlung (BCL) attached via an easy-disconnect system to the canister head
• It has a bail-out valve (BOV), and is totally removable
• It has the most intelligently-programmed integrated software for a rebreather on the market, with electronics designed for smart monitoring.
• The electronics head holds the battery compartment and the three oxygen sensors
• Any PO2 drop triggers an auto turn-on with the detection of breathing or at greater than 1.6 atm. absolute pressure
• It has diver- and back-mounted Heads-Up Displays (HUDs) that are configured for color blind and highly stressed divers through positioning and flashing or solid state. There is an alarm with vibration on diver HUD
• It is integrated with highly reliable Poseidon Xtreme first-stage regulators
• To fit the contours of the outer case, a lightweight stainless steel backplate is included
• It is rechargeable
• Depth: Maximum depth 100m/330ft
• Weight: 31kg/68lbs without cylinders
• It is available with optional CO2 monitor, VGM, Hose Covers, 5mm backplate, and Off Board Whip Kit.

Some Pros and Cons

[su_note note_color="#fef5c4" radius="0"]

The LLS is the first life support unit which is loaded with state-of-the-art technology not found on any other rebreather. The latest version, the “Expedition Optocon,” is supplied with a gaseous CO2 monitor built into the breathing loop, providing live CO2Mb readings. Some frequently-encountered difficulties that users are facing when using this device include:

• The sentinel holding negative when the ADV slider is shut, but not when the slider is open
• Negative failing via the mouthpiece
• Negative failing via the ADV diaphragm
• Diagnostic positive checks failing

[/su_note]

Recommendation

The unit automatically calibrates in air. One also needs to calibrate the CO2 sensor so the scrubber is activated by a trigger mechanism into a special seal in the canister.

In the past and with other brands, the spring base previously used to seal the canister caused many safety issues because the seal did not hold. However, the Sentinel has an automated process using a self adjusting triple lip seal.

“Unscrewing” the canister needs some force. Electrical wire is replaced by fiber optics. When in a dark room, the Sentinel looks like a Christmas tree.

There are flashing lights all over the place: the two HUD’s, the tow pressure sensors, the O2 sensors, and the temp sticks (to measure the temperature of the scrubber).

However, many people have died as a result of forgetting to turn their units on, and it is very hard to forget this step with a unit that lights up so brightly.

KISS vs. Poseidon Comparison Review 2017

KISS is a manually operated closed circuit diving rebreather. This device is a long-lasting machine, which has been designed for both entertainment and scientific diving.

There are a number of fanatics who dive using this brand, and their diving satisfaction has brought KISS into the mainstream. It is especially popular among technical, deep and cave-diving enthusiasts.

The KISS Rebreather unit is fully closed and uses a fresh, metered orifice and a first-stage regulator to bring in oxygen at a specific rate that suits the estimated metabolic rate of the diver. By using an override injection control, the diver can manually adjust any differences on a dive.

Poseidon is world’s first recreational rebreather for divers. The Poseidon MKVI is an entirely closed and ¬automated unit that will make you see diving in a different light.

The recreational unit is specially designed for divers who do not want to be technically challenged. It is easy to use and it is designed to assist the divers in the easiest possible ways.

The BOV is very simple to operate. There is only one receiver to stare at and nothing needs to be programmed; no set spots are inputted by the diver.

It is an ideal unit for a 40m max depth. No recreational diver wants to spend lots of time worrying about the arrangement and setting up of their photographic master piece while worrying about how to operate the rebreather unit.

Features

The Explorer system comes with full 13 cu ft aluminum cylinders, full scrubber, crotch belt, harness with 6 SS d-ring sets & SS clutch.

The traditional weight is 59 lb (26.7 kg) and sizes are 21 in x 14 in x 8 in. It has a buffered manual control system to add oxygen.

The oxygen is added in two ways: continuous flow and manually. The Explorer oxygen monitoring consists of three autonomous backlit PPO2 displays. Each display has its own lodging, battery and sensor, which make the system completely redundant.

The Explorer scrubber canister has an axial flow design. It is a robust, easy to fill canister that contains around 6 pounds of absorbent.

The gas flows down the center of the scrubber cylinder and then comes up through the scrubber objects, where the carbon dioxide is scrubbed out.

The structure of Poseidon contains a breathing loop such as mouthpiece, hoses, counter lungs and backpack with associated electronics module and two autonomous gas cylinders.

[su_button url="#" target="blank" background="#ee4a03" size="12" wide="yes" center="yes" radius="0" icon="icon: arrow-circle-right" rel="nofollow" title=""]Check The Best Price[/su_button]

One cylinder contains 100% compressed oxygen and the second cylinder usually contains compressed air “diluents” to balance for compression. This device has also a back¬up system to contain enough breathable gas to allow the diver to float up in case of an emergency.

The Poseidon Rebreathers have two immense advantages – they can triple actual dive time and are far less disturbing to marine life as compared to open circuit rebreathers. Poseidon’s recreational unit has four additional advantages: they are safer and easier to use, lighter and smaller, require no decompression stops and also warm breathing gas.

[su_box title="KISS's PROS" box_color="#00bf08" radius="0"]

[su_list icon="icon: arrow-circle-right" icon_color="#4b6982"]

• Closed-circuit rebreather
• Diving with a KISS is simple and stress-free
• Simple structure, easy to repair, few failure points and cheap
• Natural safety of manual CCR, a vigilant CCR diver and a safe CCR diver
• Back-mounted counter lungs are good for cave diving (no chest clutter)
• Good after-market HUD (head up display) and displays available
• Proven deep and tech diving record, excellent safety record
• Automatic diluents addition and an integrated open-circuit bail-out mouthpiece

[/su_list]

[su_box title="KISS's CONS" box_color="#bf000a" radius="0"]

[su_list icon="icon: times-circle" icon_color="#bf000a"]

• Restricted scrubber life
• Scrubber cover can catch during saturation
• Counter lungs tricky to access
• Handsets not popular, no HUD
• Essential to monitor oxygen displays

[/su_list]

[/su_box]

[su_box title="Poseidon CONS" box_color="#bf000a" radius="0"]

[su_list icon="icon: times-circle" icon_color="#bf000a"]

• Less weight – need a bit of weight to get down
• No exact scrubber duration timer
• No manual control
• Uses only two oxygen cells, more common is three

[/su_list]

[/su_box]

Recommendation

It is quite difficult to recommend one rebreather between these two rebreathers, because both of them have particular features that they offer to different kinds of divers.

But I would like to say one thing very clearly: most technical divers will prefer KISS brand for diving, while Poseidon models are better for recreational drivers.

The KISS Rebreather is the best choice for technical divers. Their philosophy is to keep it super simple. The CCR is controlled manually by the diver. Oxygen control on this product is best explained as manually controlled with backup protections.

On the other hand, Poseidon has adopted a very different approach to build a very different models. The Poseidon is better for recreational divers.

They did not want to build a rebreather that would demand technical knowledge, but instead they wanted to build it that appealed to recreational divers who just want to get into the water and enjoy a safe and enjoyable experience.

Best TEK Rebreather Review 2017

A CCR is an artificial lung (aqualung) by which the diver’s exhaled breath is partially cleanedand filtered of carbon dioxide, mixed with additional oxygen, and then breathed again by the diver.

Hence the name “rebreather.” The TEK system comes in a variety of models with a variety of features all suitable for your advanced scuba diving needs.

Why would anyone use a CCR? Most divers who try and use rebreathers do so in order to get closer to marine life. The pressure waves and noise caused by exhaled bubbles can be a huge obstruction when interacting with marine life at close range.

Different types of CCR- here!

Moist air in CCRs also stop dry mouth occurrence and lessen the factors of diver exhaustion.

Divers using equipment benefit and enjoy a greater freedom of movement made possible by lightweight, one-piece breathing units. There are a number of semi-closed systems that, when completely configured and ready to dive, weigh less than a standard 80-cubic-foot cylinder.

[su_button url="#" target="blank" background="#ee4a03" size="12" wide="yes" center="yes" radius="0" icon="icon: arrow-circle-right" rel="nofollow" title=""]Check The Best Price[/su_button]

Features

They are fundamentally complex items of equipment anddo come with a variety of advanced features, designs and system varietiessuch as semi-closed circuits and fully closed-circuit systems, also called diversification series.

Some models come with extensive sets of features such as software and electronics designed for intelligent monitoring, vibrating alarms, quick-disconnect systems, and even heads-up-displays.

Some models may even offer enhanced features of convenience. For instance, to be ready to dive, the Prism2 TEK gear diver needs only to add a supply of cylinders.

The Prism 2 model conveniently accepts a very wide range of aluminum or steel cylinder sizes, available from your diving gear supplier.

The TEK Gear Sentinel Scuba model, for instance, offers an electronics-driven fully closed-circuit constant PO2 design rebreather (eCCR) that provides an intelligent and easy-to-use life-support system (LSS).

[su_box title="PROS" box_color="#00bf08" radius="0"]

[su_list icon="icon: arrow-circle-right" icon_color="#4b6982"]

• More proficient use of gas: Gas is only used when this device needs and requires it, employing purely mechanical methods.
• Optimized decompression characteristics: By improving the proportion of inert gases in the breathing mix, this device minimizes the decompression requirements of the diver.
• Almost-silent operation: Your diving experience will become more rewarding, pleasant and enjoyable, allowing you concentrate on the visual aspects of scuba diving such as underwater photography or videography.
• Increase of bottom time: Your diving freedom can grow by using a rebreather; the bottom time can in many cases be more than doubled by doing a decompression stop of less than 10 minutes.
• Lightweight: Because of the lower weight, divers enjoy the freedom of movement made possible by modern, lightweight, one-piece breathing units.

[/su_list]

[/su_box]

[su_box title="CONS" box_color="#bf000a" radius="0"]

[su_list icon="icon: times-circle" icon_color="#bf000a"]

• Higher Costs: Obviously, because of the complexity of the design, the cost element is higher than with simple open-circuit gears. Even low-end designs may cost several thousands of dollars plus the cost for additional training.
• Risks of failure and human handling errors: They have an innately higher risk of mechanical failure as an obvious result of their design complexity. However,this can largely be offset by good a design that incorporates redundancy and by carrying adequate alternative gas sources (i.e. ‘open-circuit bailout’) in the event of a system letdown.

[/su_list]

[/su_box]

There are a few disadvantages that come along with rebreathers because of the complexity of gears. They demand a diver’s discipline to be higher and may in fact require some special training, resulting in extra efforts and expenditure.

While rebreather diving may sound scary, accidents may further be reduced by:

• Specialized Diver Training:Learn how to use the equipment and follow the procedures of using a particular design in order to minimize the chances of human-machine interaction errors.
• Higher Learning Curve: Because of the somewhat increased complexity of equipment, divers have to accept a slightly increased learning curve.

Recommendation

When you compare rebreathers on the market, consider that the TEK Gear Rebreathers are some of the most sought after scuba diving items today.

Expect and consider,though,that all models may have certain advantages and disadvantages over others. Unfortunately, a “try and dive with it first” attitude may not make you aware of minor shortcomings of a particular model right away.

This is why it is imperative to discuss with your diving instructor what type of diving gear you are presently using, as well as your goals with the equipment over the next three to five years.

Using Best TEK Rebreathers will nevertheless give you confidence that you have made a wise and technically sound choice, enhancing and maximizing your diving freedom and aquatic recreational experience.

Best Prism 2 Experience Rebreather Review 2017

Best Prism 2 Experience Rebreather is a piece of breathing equipment that is specifically designed to help a person breath where oxygen is limited, and it also absorbs carbon dioxide.

This technology is used in space, toxic environments, underwater atmospheres, mine fields, and places where harmful gases may be present.

It is a new eCCR that has already proven itself to be an outstanding model in this field of technology. It has recently been released after many years of research and production studies.

Divers choose the Prism 2 Electronic Closed Circuit as their trusted partner to explore the underwater world. Here you’ll find our opinion of its main features, pros, cons, and our overall recommendation.

Features

There are many new features included in the new 2nd model, and these added features are extremely useful and quite different from other rebreathers you can find on the market today.

[su_note note_color="#fef5c4" radius="0"]

The new version of Prism makes breathing very easy with features like these:

• Electronic CCR technology
• Primary Heads-Down Display (HDD): a battery driven LED for uninterrupted, hands free monitoring
• Over-the-shoulder counterlungs for easier breathing
• Selectable PO2 set points for pre-dive users
• Lower resistive breathing exertion and more proficient scrubber use through radial scrubber design
• Electronics located on the outside of the breathing loop
• O2 supply lines and solenoid are external from the breathing loop as well, and O2 is safely vented, removing the risk of O2 spikes due to connection leaks
• 40 hour battery life (in 70°F water temperature) with the standard 9V alkaline battery
• Sluice drains at the base of each counterlung
• Waterproof magnetic slide on/off switch included
• 3 redundant O2 sensors for reliable O2 management

[/su_note]

[su_box title="PROS" box_color="#00bf08" radius="0"]

[su_list icon="icon: arrow-circle-right" icon_color="#4b6982"]

The new Prism 2 supplies very comfortable, warm gas for breathing while diving at any depth. It never extends decompression time and allows both new and veteran divers to take advantage of its more efficient gas use.

It is made from ABS (Acrylonitrile Butadiene Styrene), providing for an improved scrubber and head instead of stainless steel versions that other models typically use.

This is a positive enhancement because ABS has less thermal conductivity compared to aluminum and stainless steel. It also reduces dusting and channeling by dampening vibration and providing continuous compression.

Another positive feature of the Prism 2 is its DSV barrel and brass-nickel-coated nuts attaching the hoses. The DSV is extremely comfortable because the DSV hover stays at eye level instead of floating up over the user’s head after removing the loop.

This product is made on reliable and flexible custom swivel regulators that provide very clean and streamlined hose steering. There are two regulators with an OPV (Over Pressure Valve) and an SPG (Submersible Pressure Gauge). All fittings and spares are US standard and designed to ensure maximum usefulness to the diver while under water.

[/su_list]

[/su_box]

[su_box title="CONS" box_color="#bf000a" radius="0"]

[su_list icon="icon: times-circle" icon_color="#bf000a"]

This device has various advantages, and people get many uses from this product, but there are some drawbacks to this product. However, these are not as significant as its advantages.

It features an easy-to-remove scrubber, but there is no removable O2 tank in the Prism 2. Most divers found this missing element to be a bit annoying, but not overwhelmingly so.

There is no stand for any unit, and it causes the unit to sit on valves as it is unable to stand up on its own. There is the potential to the valves by doing this, but they are sturdy enough to hold up to careful, repeated use.

This model gives a diver three hours in 4°C water, but it is not an excessively large scrubber at 2.5kg.

You cannot enjoy your dive as much if you use a Tech Rebreather and use the explorer. When a diver uses the explorer, there is little he or she can do.

Many users see over-the-shoulder counterlungs as a disadvantage, but it also gives the appropriate counterlung position.

[/su_list]

[/su_box]

Recommendation

This rdevice was created from a lot of experiments in engineering and design concepts. It’s creative, innovative, and reliable in the sea or any freshwater atmosphere.

People who have used the Hollis have said that they would definitely trust the model to dive with this device again, especially in an ocean environment or any other aquatic place to dive for an even longer period of time. If you think you want to buy a new product from the Hollis Prism series, you can visit their website or Amazon.

Best Hollis Rebreather Review 2017

The Best Hollis Rebreather is an electronic fully-closed circuit(eCCR), making it an ideal unit for any kind of diving, including diving in caves and wrecks. It is designed for both automatic and manual operation. Manual operation allows the diver to control the PO2 loop.

One needs only to add cylinders to be ready to dive. The unit itself has an airline-approved hardshell transport case, and without cylinders weighs only 50lb or 22.7kg, making it easy to transport by air.

Training for how to use the equipment is of the utmost importance. According to statistics, there is 5 to 10 times more risk of experiencing an incident while diving with this kind of equipment, than when using open-circuit equipment.

[su_list icon="icon: times-circle" icon_color="#bf000a"]

• Expensive, even though much cheaper than competitors
• Heads up display (HUD) can be difficult to use in the beginning
• Automatic Diluent Valve (ADV) shut-off not available
• Refilling scrubber can be a dirty job
• General maintenance tends to take longer than that of open-circuit equipment

[/su_list]

Reviews of this system are generally positive. Most divers are more than satisfied with this unit and what it delivers. The workmanship is of good quality.

The Prism 2 can be used at a wide range of depths. It can safely be used at all sports depths. This unit has been tested at much greater depths also, but diving deeper than normal sports depths brings various factors into play.

Gas volume does is not a limiting factor when it comes to diving time. It is possible to refill the Prism 2 using gas supplies from an external source.

Recommendation

The Hollis Prism 2 is a high-quality piece of equipment. It offers various advantages over normal open-circuit equipment. It does what it was designed to do.

This unit is not perfect. This by no means implies that it is not a very good rebreather. There will always be some complaints, but in the case of the Prism 2 most of these are negligible or due to personal preference.

The fact that the Hollis Prism 2 is manufactured by a well-known and stable manufacturer counts heavily in its favor. The price is also a positive point. The Prism 2 weighs in at about $9,000, which is quite hefty but is still much cheaper than many of the other eCCR’s.

The main factor in deciding for against the Hollis Prism 2 rebreather will be whether you dive enough to justify the expense. Remember that you will also have to factor in the maintenance, training, traveling and accommodation expenses. But if you have a spare $9,000 and like to get wet, this might be the rebreather for you.
