Course Overview
The Drager system works on a constant flow rate which means that the pre mixed Nitrox continually flows through a small jet into the breathing loop. The diver simply decides the maximum dive depth, and then selects the jet size to give enough gas to breathe at the target depth. The diver then cross-references a look up chart to determine what the final 02% will be in the loop, and then plans the dive. The deeper the dive, the bigger the jet will need to be to give enough gas, so therefore the available duration will naturally decrease with deeper dives. This is the reason why we recommend a 30m maximum depth, as the unit doesn't give sufficient dive duration below this depth. For shallow water diving it is ideal. In 20m of water, the SCR should give you nearly 2 hours of in water time, more than enough, and also good value from the inboard 4 litre EANx cylinder. For bailout you can fit an external 3 litre pony cylinder which for no decompression dives is ideal. There are no electronics to monitor, and the diver simply concentrates on the dive, and monitors a standard contents gauge as per normal Open circuit diving. The scrubber canister should give up to 3 hours duration, which is about enough for a weekends diving.

What will I need
The Dräger is a very simple piece of equipment. It has been designed to use EANx mixtures in a pre-mixed cylinder to maximize the duration of recreational dives. It is not intended, nor designed to handle decompression dives, and we personally recommend a depth limit of 30m for divers wishing to use the Dräger.

How long will it take
The training course is 2/ 3 days long and concentrates mainly swimming the unit on a variety of dives. Skills are very simple, mainly revolving around Open circuit bailout drills and mouthpiece recovery. The theory is completed in our classroom and doesn't hinder the enjoyment of the diving.
