VR3 Bailout question

***Beanie*** · 12th May 2006, 09:16

Your PPO2 won't vary that much and surely the VR3 won't react instantly so would smooth the peak and troughs out anyway?

Those were my thoughts too.

So, for those lucky enough to have 4th cell monitoring which works, we can avoid the nightmare which is switching to each OC gas on the VR£, and instead just concentrate on getting home.

And a BOV will make this easier. A BOV you can switch gases to will make it easier still.

(Beanie, seems like your 4th cell holder is well-timed...

Program the SCR gas with a lower FO2 than the actual 'OC' gas you are using.

This I believe is part of a CCR trimix course - at least it was part of mine

[sorry forgot - nothing to learn on ccr trimix course right

]

No its not part of the trimix course and no it wasn't part of mine.

Don't confuse the trimix course as laid down by TDI / IANTD with the personal add ons that individual instructors decide to throw in for good measure.

I suspected you had a differing opinion and thats why I thought to ask you. I've never bothered to work out a bail plan with the upward journey using SCR.

Brent.

This would be my position as well. I carry OC bailout I know how to use it and Ill use it if i can no longer reliably get my PP02 from the unit.

SCR would only ever be a stop gap to get organised or a method used if I have gone past the limits of my OC bailout.

I've been thinking about adding a 4th cell connected to a VR3, but it will create even more clutter. Three cables going from the head, 2 for the HH and 1 for the VR3, is a bit too much.

hmm I'm not sure whether to have my VR3 attached to my handset, if not the cable will just spiral down my arm in a similar fashion to a hand mouonted torch head.

What's clutter? Just the price you pay for adding extra functionality... A small price, IMHO.

I wrap my cable round my arm. Doesn't get in the way once fitted. I don't use it for deco though - the option is there if I need it.

I am toying with mounting it on the handset, however when I dived last week with a computer on the handset, I missed having the convenience of looking at my wrist.

Maybe if I get a backup VR£ I'll stick it on a handset. Do you have an umbilical torch?

I already have 2 rather big HH controllers with cables on my arms.

Dammit man! That's the front end of a truck you've got there!

And you're worried about a little cable...?!!!

(And before anyone else says it, I'm well aware that I have the other half of that truck on my back...
