reason for two computers??

[Keysdrifter454]

Is there a good reason to have two dive computers?

No reason not to have them.

Wearing them, however, is the result of paranoia.

If you don't trust your computer, get one that you can.

I just kept forgetting whether I was at my stop for 8 minutes or was it six. Now, I just reset each time I change to the next stop and I don't have to rely on my memory or write it down.

Yes, well when you get older you get "CRAF", and I'm sure I don't have to define that one!!!

OK - tell me - you're on a dive, and you look down at your wrist to check your depth. One computer says 88 feet, the other says 109 feet.

What are you checking as a reference to figure out which one right?

This is the exact senarios that I have TWO (2) computers and ONE (1) dive watch with depth guage http://www.campmor.com/webapp/wcs/s...mberId=12500226

The two computers with diff brand name, to compare the NDT limit and that is why I chose two diff type of computers to make sure that they should be pretty closed to each other. Some deviation will be expected but should not be more than a few minutes.
If one computer dies because of water leak/battery/whatever, then I still have 2 devices to check for my depth.

OK - tell me - you're on a dive, and you look down at your wrist to check your depth. Your single computer/depth gauge says 88 feet. How do you know that your computer isn't wrong and you're actually at 109 feet?

In my opinion, more information is always better than less.

A question. . .
Do you know what your bottom depth is to begin with?
If you know what your bottom is, then you'd know which gauge is wrong.

True, but taking that line of thinking to it's logical conclusion means you don't need a depth gauge at all. And what if you are diving an 800m wall?

I can't believe you fellas haven't figured out how to tell how deep you are at recreational depths without relying on a depth gauge.

Here's an earlier thread on how computers and depth gauges rot yer brain. :banana:

The relevant section starts around post #10.

No reason not to have them (two computers).

Wearing them, however, is the result of paranoia.

You have to remember: "Just because you are paranoid, it does not mean that they are not out to get you!"

I wear one wet-computer plugged into my Inspiration. I have the exact same computer strapped on to my arm.

I still carry a device to show me depth and time, and back-up tables to use with it. It is obviously less precise, but still safe enough should all else fail.

Cheers!

P.S.---Please folks, keep in mind:

(1) Ascents are ALWAYS part of the decompression algorithm. SLOW ascents are ALWAYS better (unless you are just absolutely desparate for breathing gas)!

(2) Computers do NOT rot your brain! Lack of USE rots your brain!

"Get the right tool for the job, kids!" as Mr. Natural would say (including your gourd)!!!

They probably can, sire, unless they are flying on the end of an anchor, as you have so aptly demonstrated!
