nitrox downsides

[Boarderguy]

Narcosis is not the major problem of diving deeper 40 m without He. Has density is. It may all work out fine until the one time you have a problem on the bottom, need to do higher physical effort, CO2 combined with gas density may prove to be fatal. You are off course free to do it but personally I would not dive below 40m without trimix. If not available or not affordable, I would enjoy the large amount of things to see shallower. I hope new divers get good information about breaking standards and the risks they incur.

I'm aware of that. At 190fsw you can feel the air and wob is for sure more difficult. But, with training (repetitive dives for greater duration and deeper depths) you build up a tolerance and understanding to it. It isn't for everyone and o don't recommend it, but I dive that way and means I can drop almost anywhere in the sound within 70m and use my standard double 100s.

I'm not a new diver (24 years) and plan these dives well imo.

Thread closed until we can get around to cleaning it up. This is basic, guys, not a place to be discussing 60 Meter air dives.

I almost always get free air fills, but only occasionally get free nitrox. So, that’s a downside. I tend to shore dive air and boat dive nitrox, cause that’s how the NDL depths generally line up around Monterey

if you own your tanks and your LDS won't bank premix, it can be annoying having to o2 clean your tanks
