Mdemon good 'evenin

what makes you say a BOV will save lives? it didnt help the gentleman off malin 6 weeks back.

a bov gives the user plenty of chances to breathe the wrong mix in anger and if no mix is plumbed in at all then what will happen during a proper co2 hit (not the 'go semi closed' fantasy kind)

is an 'exstream' the ideal reg for a BOV what with the pressure on 'whoosh' hope KG has double cable ties to hold it on

why is the evo rated to 'only' 80metres

the pelagian BOV is $550 when ordered with a unit or $950 stand alone
cheers

Nice to see you here!

Don't know about the Malin thing - got more details?

Anyhow, to add to the answer given above, my (gut)feeling is that CO2 hits are the most significant form of gas problem, the most common and the most likely. I've met and spoken with enough people who have taken hits to know that swapping to OC bailout is often impossible. From there, I have assumed that if you take a CO2 hit AND don't/can't bail out then you will be in a world of hurt and need the odds on your side to survive.

So, if a BOV switches you to non-CO2-laden gas instantly then your chances are improved considerably, ergo a BOV will save lives. If someone doesn't plug the BOV in then it's Darwin time and I'm really more interested in thinking of the BOV when used as planned - I could fill my Classic with jam; would that be the unit's fault if I then went diving on it and came to a sticky end? (

I've actually met someone who has taken two CO2 hits, both nasty. The first, no BOV. Not able to bailout. Fortunately still on the shotline so able to ascend safely. The second was with a BOV and this was deployed. The hit was still nasty, but the message was that the hit was much easier to control and the bailout was instant. No shotline but a safe ascent was made and the diver is still around to tell the tale.

It's easier with a BOV in a CO2 situation and anything which makes the management of the situation easier is a good thing in my book. A BOV also has other uses, some of which are mentioned in the previous posts.

So that's why I think a BOV will save lives. And that is why any manufacturer who includes one as standard (choice of reg aside!) deserves credit in my book.

KISS and Sentinel then. Any others?
