BOV Use Poll

**Robert Landreth** · 1st December 2007, 00:10

Bailing off a DSV to standard reg is just a matter of training, and should not be the problem some people make it out to be. I am not dissing BOV but my preference is separate modular systems.

Tell you what mate, jump in with an empty scrubber and test the theory.

(Let me know when and where so I can come along for a laugh. I've watched one happen so I'm fairly sure it will be a giggle.)

hi robert, if you ever had a serious CO2 hit, you would not say that!
I had one on my IDA, years ago, and I did not baill off: I could not, my mind was twisted: I could not miss that 'breathing' for 1 second. So I went straight to surface for fresh air (lucky only at 36m...)

I won't say I'm the best trained... but I have some experience

regards
paul

hi paul
o what tank do you connect you bov?
the dil tank ? 3 lt ?
How long could last a dil tank after a co2 hit with a huge co2 hit ?
in my opinion after switching to oc with you bov you would have sucked the dil in 2 minutes, I am not sure that you would have recovered a normal breathing rate.
after one sucked the dil tank what should one do ?
is there a possibility to switch the bov...
using quick connectors or switch blocks is it possible under a co2 hit ?
how many hoses will we need to be able to suck the dil tanks and then a deco tank a travel or whatever ?
imho it is gear for fear, nothing else
a co2hit is a big s t but the only methode of avoiding it is to make everything we can to avoid it.
fresh sorb...no repacking, correct packing, no effort, no stress and oc bail out if any doubt occurs, if any feeling of dread occurs....
I tend to think that if it happends....deep ...with deco....bye bye...
a bov in maybe one part of the solution , but certainely to the perfect co2 hit parachute.

jeanmi, if I use a bov, it is the OC stage, mounted on the right side of my panorama FFM, so I can nose breath if I want

in a few months, i will perhaps use my own OC/BOV :-)

it is never mounted on the internal, but on a side mounted
only using it now on one tank, but will put QC6 on so I can switch

as you see, I mostly dive withouth BOV at the moment

regards

gerstl_ossi · 1st December 2007, 17:43

A other advantage of the BOV is, that it helps to go off the loop much easier before things went wrong. I mean not the operation of changing from the loop to OC, but the mental attitude of Rebreather diver to stay on the loop. A RB-diver will make the decision to go off the loop sooner with a BOV than going on the stage tank, that I'm sure. So if there is really a problem, You start to solve it before it becomes a biger problem. So the procedure is to change to the BOV if You feel something is different than normal, check what the problem can be, or what can be wrong on the RB and make the decision to come back to the loop because all is OK or to bail out OC. My diving is not that deep, so I have the 4L 300 Bar (always full on start) on board on the BOV and a 80cuf stage with separate regulator. That works fine for me. For deeper dives the stage on the BOV would be better.

I do pactice comming of the loop a lot because I dont have a BOV but the new APD BOV is small and light the best I'v seen so far.

Hi paul
the trouble with the bov is that is a diver under co2 hit is just able to breathe and breathe at high rate , do you think he will be able to switch the CQ's ?
I remember 9 years ago , I was diving scr with 3 gases, even without any problem is was a pain in the neck to find the hoses to disconnect the bottom gas and connect the travel etc....think a little bit if you are out of breathless...
for me either the bov is connected to all the bail out tanks so that the diver can change gasses very easily, or it is useless for co2 hits.
and if we have to connect the bov to the dil, the travel and the deco the Rebreather will look like a spaghetti plate, and one won't be able to pass his stag to a buddy in case it is necessary...
bov is a new fashion.
regards
jean mi

Stephane · 1st December 2007, 21:06

Hello Jean-Mi,

I think that Paul means that he has a QC connector on each bailout regulator so he can change gas without going off the loop.
The BOV is connected on the bottom bailout tank so it can be activated in one second.
I have a similar setup and I hope I will never have to use it!

hi stephan
I caugth what paul said
I think a diver under co2 hit won't be able to change the oc's
if he is it means he is able to switch from cc to oc without a bov
