1. 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.
- It already comes completely assembled. It is ready to be used straight out of the box.
- It comes with an easy-to-read display that will tell you about your oxygen levels. However, you can also make the necessary changes as needed.
- It is easy to make changes. Simply flip its level integrated on the unit’s mouthpiece and then switch to another regulator without having to disengage the brakes.
- Because it operates using MAV or Manual Add Valve, this rebreather allows the users to input more oxygen as needed to ensure that oxygen levels are within the recommended range.

- There is very little drag with this rebreather, contrary to popular belief.
- It operates quietly.
- You are also able to use less gas when diving.
- There aren’t a lot of negative reviews about this rebreather.
