which computer is the best VR3 or HS explorer ?

When I sell an explorer, I make up a laminated Cheat Sheet fro my customers...

That'd be useful... Alternatively, that is the reason I like the VR-3 with on-screen prompts.

Anyway, if the diver is using the computer all the time, it is a moot point. But I am glad we had the discussion since it reminded me how to do OC-bail-out on the VR-3...

I think you mentioned using it with integrated-sensor ?

AFAIK, the HS that I seen only has the cable coming out of the left side of the case. Which means you could only wear it on your left wrist -- just in case that's an issue to you.

The VR-3 screen could be rotated 360-degree in 90-degree increments.

Why so low fiO2 in the diluent ?

As thats the nicest heliair mix....you know just add the He then air top.....why worry abotu the o2 when I dive a CCR which injects o2 and I dont bail ever to the onboard dil.

No right or wrong answer!

In that case its the one you can find cheapest or who's customer service you best like the sound of.

or which deco alogo you prefer.....

Of course, I forgot that you carry a different mix stage for bail-out. Never mind...

Except just a little more difficult to compute in your head when doing diluent flushes, unless you carry a cheat-sheet like Joe.

I am confused now

what would I calculate in my head? Not sure what you mean but taking a stab - if I had a cell go I would check the milivolt outputs rather than doing a dil flush but if my onboard dil went tits up I would just switch my computer to using other dil.

Naaa, they're all pretty much the same anyway...

If in any doubt 1@9 and 9@6 for less than 45mtrs or double it as you go deeper.... Its all blackmagic a witchcraft anyway, so long as you've got something with pretty numbers on it to show the guys and gals on the boat they'll never know you're winging it, works for me <touch wood>

Why is it my buddies never want to dive with me a second time?

I can tell you a perfect case when cells "fail"high..

say you had one or two cells that had water droplets on the that you didnt see befoe you calibrated... now you calibrate all cells will have the same po2 value once calibrated.. now once the moisture drops off the cells tose two cells will be reading much higher than normal.. now lets assume your cll that is actually calibrated correctly was one that normally has a lower output say 40mv in oxygen, which is perfectly acceptable..

you would look at your sensors and see one is lower than the others and conclude its the bad one.. if all 3 cells are reading about the same hopefully you would conclude you screwed up with the calibration.. If you do a flush with a know mix at a specific depth it will at least tell you if the cells are operating where they are expected to at the depth you are at..

On the HH you dont have to calculate anything just select the fo2 function and it will tell you what the loop is expected to be on a flush, otherwise use a gas you can easily compute,memorize of carry a cheat sheet..

Fair enough, but I, as am I sure you Joe never calibrate my head with water on the cells!
