Differences between 'Boris and Sentinel?

ccr_ada

i was told it was going to be an option on the sentinel not to have the new BOV and you could up the spec on the hoses to the nice green ones

Well, see, I'm not actually quite sure, see.....

But I just checked the Jetsam site there the BOV afaik is listed as standard.
The pelagian I cannot be sure of - I cant tell from their site. But I know its app. 1000 bucks to get it for a rEvo

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

Hi mark good to see you on the board,

I believe having a BOV is defiantly better than not having one at all especially when looking at dealing with unconscious divers or to provide you with a quick fix while you bailout fully, I have seen on several occasions divers fix a problem using this tool were it could have become quite an issue had they not had one( hypoxic issue on a Meg)


I have ordered a sentinel without the BOV for this very reason, I have several extremes and would not like one as a BOV. I am interested to know why this has been chosen. I hope to adapt my ffm with apeks second stage to it same like Boris this is defiantly the way to go.

Cannot afford not to buy it as an upgrade at that price when you buy the unit.

Cheers

BOVs are standard on both KISSes. its been one of their fundamental differences for many years.

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?

PS The choice of reg is an interesting one. I guess the Poseidon will give you gas at depth which is more than most(/all?) of the standard regs which come with a BOV. The crappy one which comes with the Divematics got swapped for an XTX50 on mine. Shouldn't have to swap out the reg, so interesting again to see the Sentinel's choice. The AP reg is supposed to outperform everything so again it will be interesting to see what depth rating that is given using trimix.

Sentinel uses xstream 1st stages so its a logical choice to use xstream 2nd stages.


I cant think of a better breathing reg at depth than the xstream.


IMO low WOB should be the no.1 priority when choosing a BOV. Its physical size should be wayyyyy down on the list of priorities because when you need it, when you really need it, a high WOB could hinder or even prevent recovery.

With the xstream you get both low WOB and small size. I used them for a while on my inspiration.

Be interesting to see it develop

Aside from getting way off track from the Boris - Sentinel discussion,
you can order the Divematics with or for just about any 2nd stage you want.
I've seen them with Poseidon Xtreme, Jetstream and Cyclon, Apeks ATX100
and TX50, Atomic M1 and B2 and Oceanic Omega 2. Am quite sure there have
been and will be others.

Anyway, time to get the thread back on track, there's a forum for DSV/BOV issues.

Differences between 'Boris and Sentinel, anyone?

Long shot, but whats the weight of the Sentinel?

I'd be guessing, but comparing it it other breathers it looks as if it would be under 23kg to fly with whereas the Boris is what 32kg odd?

Current airline baggage limits, could make that a little different to travel with...
