1. Hollis Prism 2 Rebreather
One of the much-talked about rebreathers today is Hollis’ Prism 2 Rebreather. It has either front mounted or back mounted counterlungs. The front mounted counterlungs is beneficial for divers looking to get top-notch displacement. That is because it has a reservoir that mimics the displacement of the volume of your own lungs. This feature lowers down hydrostatic loading. With the addition of a manual and an automatic gas addition system, you can get control over your rebreather.
It can also be back-mounted, so you can free up your chest area in case you want to bring additional tanks, or you have more accessories to lug under water. Back mounting also reduces drag.
The Prism 2 is one of the most reliable scuba rebreathers out there with its ADV Upstream Valve that is impervious to free flow. This will, in turn, help in adding diluent gas. It features T-pieces that trap water and prevent water from getting inside the breathing loop. Draining excess water is also easier.

A standard in your purchase is the Dive Surface Valve or DSV but the manufacturer gives users the option of customizing their rebreather to their specific needs. With this one, you have the option of getting a Bailout Valve or BOV. This is a more lightweight option compared t DSV. A
The HUD or Heads-Up Display is well-designed. It comes with 3 LED colors that will tell you the status of your rebreather. This will let you know your oxygen levels through its built-in sensors. Since it is eye level, you can easily see if there are changes.

2. Kiss Rebreathers Orca Spirit mCCR OW Package
Rebreathers aren’t exactly known for their affordability but if you are looking for a slightly more affordable choice, this shouldn’t disappoint. This is different from the others because this is missing the usual twin tank setup. What this has is one oxygen cylinder found at the base of the rebreather. The Diluent comes from a separate off-board cylinder. You can choose to mount it either on your right or left.
It is through a hose fitting that diluent gas travels to the Spirit. It eliminates the need for two cylinders as just one cylinder functions as both the bailout and the diluent at the same time. As a result, it reduces the usual heft that can be experienced from a typical rebreather setup.
This rebreather has a smaller and more compact profile, great for divers who want something more lightweight and less clunky. It is only 13.5 inches in width and is 23 inches tall, so it is one of the slimmest profiles out there. Without the tanks, it only weighs 9.5 kg.
Fewer parts mean fewer maintenance work.
