two divers, one computer?

[jeckyll]

For someone to come away from a class at any level not knowing that each diver must be self-sufficient and cannot ever share life support equipment is inexcusable. If a diver doesn't have a computer, then he/she MUST be diving using a set of tables and a bottom timer. Should have that even with a computer in case the computer fails.


Might as well just have one tank between you - heck your buddy has an octo that they never use and without a tank you'll be faster.

Computers really are not life support equipment. If you dive tables you should be able to live, no? Is it ok to share tables?

Seriously, as has been pointed out, the issue is repetitive dives. Doing a single dive limited to 60 fsw (given that we're in the new divers forum) for less than 50 minutes the computer isn't doing very much. Most new divers won't get 50 minutes on a single 80 anyways.

Repetitive dives are a different story of course. But treating the computer as the end all is a mistake IMO. There was a very good thread a while back that showed the large difference that different computer models have. They are only a tool, and knowing how they work and where they fall regarding conservatism is essential.

Hopefully new divers ... strike that, any divers(!) are not pushing the computers to the limit without fully understanding how the particular computer calculates NDL's, it's level of conservatism, adjustments for the conditions (i.e. cold water) etc.

Just my $0.02.

We are in agreement. My point was that each diver must be capable independently of peforming their own deco calculations. To go diving without that capability, especially as you point out in repetitive situations invites a hit, and depending on how bad and where you are can make some form of calculations life support.

I like to have my own computer.

Please use something though... I have dove with a couple of people that didn't use tables or a computer. They where new and I don't know where they where trained.

ONE diver, ONE BT/computer/table.

Else don't do it. Dont get tight ($) on these things. If you want to do the sport/hobby... pay for the minimum goods.

You should always do your deco or even non deco computations yourself. You shouldnt rely on anyone else to do it for you. The fact is if you both do the same dive one will go deeper, stay longer, or chase more fish than the other.

If your life is worth $50 worth of tables and timers or a $200 computer I guess you wouldnt have much of a need to ask questions on here. That being said listen to the other posters get a computer for each of you or dive the tables but whatever you do keep track of your own deco status because in the end its your life.

It's my turn ####it!...Noooooo, it's MY TURN ###hole....You used it last! Did not...Did too...Did not...Did too, Did too, Did tooo....LET GO Dip###...No Yoooou let go...Look at what you did now...You broke our only computer...Did not...Did too........

.... what about buying 1 PDC and 2 transmiters ???

That not a good idea two divers sharing one computer, you buddy need a DT and backup dive table

Was only being sarcastic .... :14:

Just don't know why someone would ask such a question ....

Could next thread be : " Can 2 divers dive on 1 bottle of air ? " or " If I have a hangover, is it safe to dive ? "

OK, now that everybody has gone ooooh and aaaaah about how horrible a thing this is, explain to me why "non-computer-wearing buddy stays shallower than the one with the computer" sort of plan is worse than diving tables.

In both cases, you have some restrictions on allowable depths. When sharing a computer, you just have the additional one of "not deeper than the guy with computer" (and of course, in real life if you dip a bit deeper for a minute or two, you just make sure you are at least the equal amount shallower for a while).

Sharing a computer isn't ideal, but I don't see it as the horribly dangerous sin that others seem to think.
