Poseidon MK6 Rebreather

The Poseidon MK6 Discovery was the world’s first rebreather for recreational divers and the first to be approved by PADI as a Type-R recreational rebreather for PADI Rebreather courses. It’s a fully ­closed, fully ­automated unit that will make you see diving in a different light.

The Poseidon Discover MKVI is so simple and safe to operate that it can be used for entry level rebreather diver training, right out of the box. Because the unit has an open circuit (traditional scuba) alternate air system, PADI have set the minimum prerequisite of a qualified entry level diver with some open circuit diving experience.

When you are ready to further your rebreather diving the Poseidon MK6 can be upgraded to a 60m technical rebreather and is on the PADI Type-T register for Tec 40 CCR and Tec 60 CCR

Kiwidiver provides training on the Poseidon MK6 from beginner level to Instructor.

Poseidon MK6 Size

Poseidon Discovery MK6 Recreational Rebreather’s Extreme compactness at only 15 kg / 33 lbs ”ready to dive” and 8 kg / 17,5 lbs “travel weight” the MkVI Discovery is one of the world’s smallest rebreathers. Take it as carry-on baggage when flying. Enjoy the freedom.

Yet it is not “lightweight” in terms of performance – you get three depth-independent hours of near-silent diving.

Auto Calibrating

Poseidon Discovery MK6 Recreational Rebreather had the first truly auto-calibrating and autovalidating rebreather. The MkVI Discovery
uses a patent-pending automated method to verify that the oxygen sensors are working properly at all times – both before and during a dive.

On your Poseidon Discovery MK6 PADI Recreational Rebreather Course in Phuket, Thailand you will see just how much time this saves you and how safe and convenient the Poseidon rebreather is.

Poseidon Discovery Intelligent Battery

The Poseidon Discovery has an intelligent battery – it’s your personal power and data storage system. Plug it in and the system knows it’s you, as well as your dive history, including repetitive dive information.

Remove the modular battery, put it in your shirt pocket, and take it home to recharge it. When you are ready to dive, take the battery from the charger and plug it into the MK6 rebreather.

Technical diving – All you need is a new battery
Upgrading the Poseidon MKVI is easy. It is only a battery change away. The 40M Yellow Battery allows dives to 40 metres with decompression. The 48M Blue Battery allows dives to 48 metres with decompression and also allows the use of trimix.

Poseidon Scrubber

Poseidon Discovery MKIV Recreational Rebreather uses true plug-and-play carbon dioxide absorbent cartridges. Simple and fast to use. Pre-packed axial cartridges of SofnoDive® 797 absorbent give you 3 hours minimum diving range and can be changed-out and replaced in seconds.

These are readily available from Kiwidiver in Phuket.

Poseidon Discovery MK6 Switchable mouthpiece

In a significant new patent-pending design, the Mk6 Discovery gives you the ability to switch from closed-circuit to open-circuit operation in one easy motion, without the need to search for a spare mouthpiece in an emergency.

The ultra-compact switchable mouthpiece is lightweight and easy to breathe, giving you high performance in both open-circuit and closed-circuit modes.

The Mk6 Discovery mouthpiece also combines in the same housing a pressure balanced“ Automatic Diluent Addition Valve” (ADV) that compensates for breathing volume in closed-circuit mode, so that you will never run short of a full breath during a dive.

Rebreather Interface

The Mk6 Discovery contains five separate warning and advisory systems so that you get the information you need to manage your dive without the task-loading normally associated with rebreathers. The main Mk6 Discovery data interface is a large format flat screen panel that displays all you need to know about consumables management – cylinder pressures, dive time, depth, oxygen level, and it incorporates a sophisticated resource algorithm that monitors all systems for you and tells you when its time to head up.

 

If things are not going correctly for whatever reason, the MkVI Discovery has audible, tactile, and visual warning systems to get your attention, and to advise your diving partner of your status.

Maintainance

Easy maintenance of Poseidon MK6 allows the entire rebreather to break down rapidly for washing, drying, and storage. No tools needed. New software releases can be downloaded and installed over the internet

The PADI Recreational Rebreather course teaches you how to break down and maintain the Poseidon Mk6. It teaches you what components are user serviceable and which need to be returned to the shop for maintenance.

Firmware upgrades are free, equipped with the latest sensor calibration and validation algorithms and makes the MKVI more stable in varying temperatures in different environments in all kind of waters. No other rebreather on the market has as sophisticated systems as the Poseidon MKVI to determine whether a sensor is reliable or not. This is achieved through the patented O2 sensor calibration and validation routines.
