Deeper Diving equipment

[Doppler]

Am beginning to work with a tec diver instructor on some go/no-go laminated check list cards. If it is not 100% then take the time to make it right before going into the water. If any anything on the list is a no=go then the dive is delayed or canceled until it is fixed.

Checklists are a good start, Curtis... when they are used.

An equally good habit to develop when using one is to work through them using CHALLENGE & RESPONSE... As in: Deco Regulator wet pre-breathe?! CHECK!

However, do understand that a checklist is just one part of the system.

Dive safe, mate.

Rebreather complacency kills...

As does open-circuit complacency... nothing special there.

Any recommendations for a dive computer for trimix?

No need, friend. Save your $$

I am gathering from this thread that you are just starting tech training. If so, then you really don't want to be thinking about this.

The first thing you need to do is pick out an agency and instructor. You will then learn what that agency/instructor think about this topic.

Some agencies/instructors never, ever use computers for any of these dives.

Most of the agencies/instructors that do use computers for these dives often do not use them for the first stages of of training. When you have gone through all the basic decompression training, then you can start thinking along these lines. By the time you get there, the market for trimix computers will be very different from what it is today.

Don't look for a trimx computer until you know for sure you are going to use it.

YEP, Your brain... learn the curve and get several mix dives under your belt and then consider if your diving warrants you spending $1400 on a computer. Otherwise invest in deco software and learn what decompression is, 'cos a personal dive computer is not gonna tell you.

Read John's post above a couple of times and try to understand where he is coming from.... this thread started out with you asking about regs for 500 foot dives and now you want advice from a bunch of punters on the internet on how to part with more than a thousand bucks... you don't know us from a hole in the wall. Go get some diving in... then tell US what you've learned.

Going along with what Doppler just said, there's no use buying a computer until you decide what you want to run on it. "Deco for Divers" would be a good place to start.

I learned that my computers have always failed at the most risky times, and that I don't actually trust them.

If my life (or ability to walk and/or not pee into a bag) is on the line, I want a depth gauge, timer and printed plan and a buddy I trust.

Nothing says "Oh Crap." like being at a hundred and something feet and seeing "Signal Lost" or "E6" or a blank screen or a test pattern.

Always struck me that pre-dive inspections will show up the faults and pending failure of a lot of pieces of kit... but never a computer. As you say, they fail according to their own agenda.

Curtis if I have read your previous posts correctly you were just certified 4 months ago I think you need to slow down and do some realistic diving and forget about 500 feet,tri-mix computers etc.etc..

There is a LOT to learn and accomplish before considering what you have eluded to.
