This is a true breakthrough!

Rebreathers have been around since the early 1900s however, a good simple, reliable, scrubber duration warning system has proved elusive - until now.

The display shows you not only what is happening in the scrubber, reflecting the diving conditions, but also warns you before CO2 becomes an issue. Unlike a CO2 sensor which warns you when CO2 is coming through (which is too late when you are deep) the Vision’s Scrubber Monitor warns you in advance of CO2.

Depth, work rate and water temperature are the three major factors affecting a scrubber’s duration and the APD Scrubber Monitor considers all three factors simultaneously – even working for partially used Sofnolime.
