Same here! 0.8 is overkilling the safety margin!NDL dives 1.4 or 1.5
Tech dives 1.4 for bottom mix and 1.6 for deco
When the oxygen set-point was raised to 1.4 atm, there was no DCS in 17 no-decompression dives to 100 fsw for 40 min and 1.7% DCS in 58 decompression dives to 100 and 150 fsw for 60 min. At an oxygen set-point of 1.6 atm, there was no DCS or oxygen toxicity during 13 no-decompression dives to 150 fsw for 10 min, but an oxygen convulsion occurred after 40 min during a single dive to 100 fsw (40% F1O2). The diver had exercised underwater at a measured oxygen consumption of 1.6 Lpm and noted high breathing resistance that was confirmed during post-dive tests.
or the inverseYou are fine with 1.6 - although the standard is 1.4
The idea is that if you use 1.4 and you dive a little deeper on accident you still have 0.2 as a buffer. But if your responsible and pay attention you can use 1.6 as a hard MOD. Some even push past 1.6 but that's not smart.
When filling out the MOD info on the label at the dive shop, which MOD do you use PO2 1.4 or 1.6? I've been reading different messages and most say they use PO2 of 1.4 where my instructor said to use 1.6.
Any thoughts?
