GSS CO2 sensor increases diver safety

Recreational diving is enjoyed by people around the world, and diving with rebreather equipment is booming. Rebreather technology recirculates the air, removes the CO2 and tops up the oxygen level. As a result, a small tank of air and a small tank of oxygen is all that's needed, rather than big tanks of compressed air.
