The Azimuth is a very simple piece of equipment. It has been designed to use Nitrox 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 30 metres on the unit. The system works on a constant flow rate which means that the pre mixed Nitrox continually flows through a small oriface into the breathing loop. The diver simply decides the maximum dive depth, and then adjusts the metering valve 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 higher the flow rate 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 30 metres maximum depth, as the unit doesn't give sufficient dive duration below this depth. For shallow water diving it is ideal. In 20 metres of water, the SCR should give you over 2 hours of in water time, more than enough, and also good value from the inboard 4 litre Nitrox cylinder. For bailout it is fitted with another 4 litre 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 OC diving. The scrubber canister should give up to 3 hours duration, which is normally enough for a weekends diving. The training course mainly concentrates on swimming the unit on a variety of dives. Skills are very simple, mainly revolving around OC bailout, mouthpiece recovery, cleaning of the unit, and scrubber repacking.
