OUR TOP PICK

Summary

As a general rule, rebreathers are not known for being affordable but if you do want something that’s a little bit more catered towards a lower budget, then the Kiss Rebreathers Orca Spirit mCCR OW Package could be a good choice for you. This is somewhat different from the other option because it doesn’t come with the normal twin tank setup that you tend to see on rebreather packages. Instead, it comes with an oxygen cylinder that you find at the base of the rebreather. The Diluent then comes from an off board cylinder. You can mount the rebreather either on your left or on your right.

The rebreather is through a hose fitting that diluent gas travels to the spirit. Essentially, you won’t need two cylinders as a result because one cylinder alone will function as the bailout and the diluent at once. As a result of this, it’s not as heavy as a normal rebreather setup.

Pros

  • The rebreather features a much smaller and thus more compact profile. This is ideal for any divers that want an option that is more lightweight and a little less clunky. It only measures 13.5 inches in width and it’s 23 inches tall, so it’s certainly one of the slimmest options out there. It also only weighs 9.5kg without the tanks.

  • There are fewer tanks which means there isn’t as much maintenance work required.

  • The device already comes totally assembled, so it can be used right out of the box

  • Comes with a display that’s easy to read and will tell you about your oxygen levels. You can also make changes to your liking as necessary

  • It’s Simple to make changes, and all you need to do is flip its level integrates onto the units mouthpiece and then switch onto another regulator without needing to disengage the brakes

  • It works by using the MAV or Manual Add Valve, so the rebreather actually lets the users add more oxygen as is needed to make sure that the oxygen levels remain in the range recommended.

  • The tank can last as long as four hours which means that you have plenty of time to dive in one day

  • The rebreather doesn’t have a lot of drag

  • Quiet operation

  • Requires less gas when diving

Cons

  • There aren’t many negative reviews for this rebreather

Summary

The Kiss Rebreathers Classic Explorer package is pretty similar to the standard setup that you will find in most rebreathers that are currently sold on the market. Sure, it does lack some of the more creative features that are in the other products we explore on this ranking, but the simple functionality make this a truly fantastic choice. It’s very easy to understand the controls and mechanism. 

The rebreather has a tank like build due to the counterlung case that will give the support to the counterlungs. This also makes installation a lot easier and it’s much more simple to maintain because you can get access from the top. One thing that is a little bit different with this product is also the scrubber, which features an axial flow that essentially gets rid of the used gas through a center tube, and this travels to the back of the scrubber to properly get rid of carbon dioxide. It is very easy to carry around and it is impervious to channeling.

Pros

  • The functions are simple and straightforward. Its user friendly nature makes it one of the best rebreathers for beginners

  • It’s one of the most durable rebreathers on the market. It works well even in some of the harshest water conditions. It’s also possible to use it for cave diving because it comes with systems that are suitable for deep cave diving. The materials are also election grade

  • The BOV has dual functions, and this allows you to quickly remove the breathing loop even when you are switching to an open circuit system. All you need to do is twist its knob that is included and you can use it. The BOV is also a particularly handy tool when it comes to preventing panics.

  • Because it is back mounted it gets rid of any obstructions in the chest area

Cons

  • It doesn’t come with all of the extra features that a lot of divers may prioritize

Summary

One of the most talked about rebreathers on the market right now is the Hollis Prism 2 Rebreather. This rebreather has either front mounted or back mounted counterlungs. The front mounted counterlungs are handy for any divers that want to get top quality displacement, as it has a reservoir that copies the displacement of the volume of your actual lungs. This then lowers down hydrostatic loading. It also has a manual and an automatic gas addition system, which means you can get control over the rebreather.

You can even back mount the rebreatherm so it’s possible to free up the chest area if you want to bring extra tanks with you, or if you have a few more accessories that you want to take under water. The back mounting capabilities also means that you can reduce drag.

This is by far one of the most dependable scuba rebreathers on the market with the ADV Upstream Valve it sports, a feature that means that it is impervious to free flow. As a result, this will help with adding diluent gas. It has T pieces that trap the water and it also stops water from getting inside of the breathing loop. It’s also a lot easier to drain extra water.

Pros

  • It can either be back or front mounted, which means it can suit a range of different divers. This also gives more flexibility because you will be able to alter your setup to exactly what you need

  • The device comes with the Dive Surface Valve, or DSV, but the manufacturer will give users an option of customizing their breather to their own needs. With this one in particular, you will have the ability to get a Bailout Valve or BOV. This is a little bit more lightweight in comparison to a DSV. 

  • The HUD or Heads Up Display is designed well, coming with 3 LED colors that will show you the rebreather’s status. This will show you what your oxygen levels are through the built in sensors. As it is eye level, you are able to easily see if there are any changes. 

  • It comes with the Shearwater Petrel computer system. This is certainly one of the most advanced today, especially as far as CCR operations are concerned

  • The rebreather is more lightweight than a lot of other rebreathers on the market. It only weighs 47 lbs, so it’s a great choice for anyone that doesn’t want to carry a lot of weight

  • You can find the power switch externally, so it’s simple to turn it on and off

  • It comes along with an O2 calibration system that is simple to use and it works just by touching a button

  • The battery life is long, lasting for as long as 40 hours for seamless scuba enjoyment
