Introduction

KISS is a manually operated closed circuit diving rebreather. The KISS Rebreather is a long-lasting machine, which has been designed for both entertainment and scientific diving. There are a number of fanatics who dive using the KISS, and their diving satisfaction has brought KISS into the mainstream. The KISS 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. The rebreather 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 KISS Explorer Rebreather 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. The KISS Rebreather has a buffered manual control system to add oxygen. The oxygen is added in two ways: continuous flow and manually. The KISS 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 KISS 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. One cylinder contains 100% compressed oxygen and the second cylinder usually contains compressed air “diluents” to balance for compression. The rebreather 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.

Pros

KISS Rebreathers are:

  • 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

Poseidon Rebreathers are:

  • Very easy to set up and use
  • Pre-packed canister
  • Use of extend air cartridges saves time and effort
  • Pre-dive checks are concluded by design
  • Closed-circuit, automated rebreather (eCCR): The Poseidon Se7en Rebreather

Cons

KISS Rebreathers are:

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

Poseidon Rebreathers are:

  • 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

Recommendation

It is quite difficult to recommend one rebreather between the two rebreathers, KISS and Poseidon, 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 Rebreathers for diving, while Poseidon Rebreathers are better for recreational drivers.

The KISS Rebreather is the best choice for technical divers. The KISS philosophy is to keep it super simple. The KISS CCR is controlled manually by the diver. Oxygen control on the KISS Rebreather 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 rebreather. The Poseidon Rebreather is better for recreational divers. They did not want to build a rebreather that would demand technical knowledge, but instead they wanted to build a rebreather that appealed to recreational divers who just want to get into the water and enjoy a safe and enjoyable experience.
