Morning all.

I am new to rebreathers and as such I am still wallowing around happlily in the 20metre range practicing drills and just getting used to my Inspiration Vision.

However my personal problem or concern is that I dont feel that the scrubber is working as well as it should. Having dived on the weekend the scrubber was up to 3hrs and 15 minutes. The Temp Stick was in the middle of the range. set point was at 1.3 and only using air as dil. Water here in Sydney is about 18C BUT... I dont feel as though my breath is being quenched. I certainly am not working hard.

Last month I ran the unit and the scrubber time got up to 5hrs and 10 min and again the temp stick still showed that the scrubber had ample life. 25 minutes into a dive however I recognised the obvious signs of a CO2 hit instigated a series of loop flushes and returned to the boat to live and dive another day. That little gem gave me a migrane until Monday Night...! But regardless of the calibration of the temp stick I have set a marker to replace sorb at or just after 3 hours from now on.

I have never run the scruber to the temp stick warning and so my question is how reliable are these temp sticks as an indicator of scrubber life? and is 3 hours being a little too conservative?
