Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

Hi Ginti,

Thank you for your input. I agree that if you stretch things, you may be able to achieve Mod 2 level in under $20K which should enable you to dive to 60m on trimix. If you want to stretch things, I have no problem with that.

Let me clarify - 20k is the cost WITHOUT stretching. It's really the maximum (maybe only the GUE route could be sligymore expensive, and not much).

If one wants to stretch things, it's going to be less most likely

Obviously rebreather divers have the option for either; OC divers have no other choice than OC.

yup. I will not spend the money to learn CCR. Money is not my issue. Now as for deep dives on air.. yes this was normal with BSAC in the 1980's and these were deco planned dives. It's uncommon for me to do deep dives on air nowadays as it's not really in recreational diving. There are some dives I do in Indonesia that are to 50m on air with light back gas deco. I seem to be fortunate that I might be in that 20% of divers who don't get narced so easily. I'm also better on gas consumption than most other divers.

I am not Trimix trained. Try getting that mix anyway in some parts of Indonesia. It's hard enough getting Nitrox.

I definitely won’t be spending 20k and 2 years training to make dives I’m already making for 50 euro including fuel. People should just stop comparing narcosis to drinking alcohol, either they have no experience of narcosis or they need to get out more.

Ok boomer.

As a boomer, allow me to ask what the letters F O mean to you? You can make fun of us boomers all you want, but at least we could have sex without being wrapped in a inner tube.

Point is a moderate number of dives with $200 fills will add up faster than you think it will,

50 trimix dives may be a moderate number to you, years worth to others. My last dive partner and I tried several times to figure out the cost effectiveness of a rebreather. Couldn't make it work for us at the time. Of course, although we occasionally did, neither of us really wanted to spend more than 3 hours in the water.

From the sounds of it, it was a single test. If you have ever been narced, you will realize it isn't 100% repeatable.

I can attest that for me, this is true. We did a lot of "deep" air diving because it was all that was around. The theory at the time (1975-77) was that you built up resistance to narcosis. I don't think you had any resistance, but by repetition, you just kinda got used to it. Never got used to freezing my ass off doing air deco.

I am not a proponent of "deep" air diving, whatever that means to you. I still believe that, for the occasional deeper dive, trimix is relatively cheap.

You want a rebreather, hell, go and buy 2, you probably will anyhow when a newer model comes out. If you believe they are safer, then they are. Whatever puts you in the water with the most confidence and comfort, is fine with me.
