Backup Computer?

[Bubbletrubble]

no worries, you'll likely one day be one of those people standing in line on a mutual trip asking me if you can borrow some of my spare parts/gear...program your computer.....try out my new toy.....help you configure your gear...get gear recommendations....and you can be the newest member of my 'he saved my bacon' fan club!

Honestly, I have no issues with you bringing along an extra reg setup, spare parts, etc. I also think it's wonderfully magnanimous of you to be so helpful to others. I was just poking a little fun at your comment about carrying 3 computers (sometimes) on a recreational dive.

Perhaps you just have something against Men At Work.

I use two Suuntos on every dive, but very different models. I have my back-up on my console and my primary on my wrist. I monitor both during the dive to make sure they are both similar.

I don't even bother with a bottom timer anymore.

I seriously doubt it. I suspect I have been diving longer than you and just might have more bottom time, too.

Lol, I also use two Suuntos on (most) dives. They stay in gauge mode, though (functioning as bottom timers). I think computers are fine (if you understand what they're telling you), but as others have mentioned, they're hardly necessary.

Using tables doesn't have to mean limiting bottom time based on max depth...

I'll bite. So if you use tables and depth averaging to regain the lost bottom time, are you not then loosing the added safety/ultra conservatism of the tables?

 

[Rainer]

Of course. That's exactly the reason I (and others) use average depth in lieu of max depth. The reality is, you still end up inside the normal curve of "safe enough", just like those that use computers in lieu of tables based on max depth. In both cases, you give up some conservatism (while staying conservative enough to avoid [even subclinical] DCS), while maximizing bottom time.

I suspect you are building in conservatism by doing a staged ascent. That's rather different than the 60 fpm direct ascent the tables assume.

 

[Rainer]

There's plenty more to it that just average depth and ascent strategies, but that's a matter for a different discussion (e.g. gas choice, shaping of bottom depth relative to dive time, surface intervals, modifications for repetitive dives, etc). The larger point is simply that one can safely dive bottom times comparable to computers without having to actually dive one.

...using Sunntos probably isn't helping your bottom time stats.....
