In general does the OTU count keep you out of the water before you would be able to make 7-8 hours of diving in one day (i.e PPO2 @1.3 2 1/2 hours around 200 OTU's).
So run a lower set point like 1.2

In other words extremely deep diving for an extremely long requires a large scrubber. How common is multiple hours diving multiple times a day?
Extreemly deep? is that past 30 or past 100m? It depends on the perspective of the diver i supose. If its more like 100 to you then get a Vision.
I am aware of a diver who runs his Evo to 6 hours and hapily does a deep dive in the morning (60 -80m) and a shalow dive in the afternoon (max 30-40m). He is still alive but personaly after any dive to 60-70m+ I change the scrubber. Its £7.50 so wy risk it?
