KISS Classic


Training through our Recreational or Technical path

The Classic KISS is best known as the ‘manual oxygen' controlled rebreather. There is no electronic controlled Set Point which tracks and controls the partial pressure of oxygen in the breathing loop. What it does have is a constant flow orifice that continually allows a small amount of oxygen into the loop and supported by manual addition oxygen valve which the diver uses to maintain their own Set Point.

This system demands a certain amount of attention by the diver, as there are no alarms, lights or any other type of signaling device to alert the diver. This means the diver is not relying or trusting on anything other than themselves and the skills they have learnt during their training.

RAID training is demanding with a simple philosophy - Train Hard and Dive Easy
