Off with the BOV

After a reasonable time diving my Meg with the Golem Shrimp BOV, I have decided to dive with out it for a while.

I acquired the Shrimp after fumbling while looking to find my bail out reg at depth. I reasoned that I would have been in trouble had I really needed it. Since then I have put about 100 hours on the Shrimp and have few complaints as it is well built and not hard to service. Mind, I have had to service the the oc bit on the side of the road.

But, it is not as comfy as the DSV. When scootering the BOV feels huge. Today's dive with the DSV was a delight and it felt that the breathing was easier. Getting ready to dive and general tank handling was a breeze. The HUD is in a better spot for viewing.

One of my principle reasons for the switch is that it is time for some deeper dives. I am not at all attracted to switch blocks and slider shut offs. I played a bit with them, but prefer a simple and robust system with the fewest moving, or serviceable, parts.

I have also determined that I will not have something in my mouth that I cannot breath. When I have plugged and unplugged the QC6 while diving I have found this to be difficult at best. Yes my rig is run as an O2 breather in the shallows, but what would be the point of having a BOV plugged in to a hypoxic mix at the surface?

Ironically my dive partner was today breaking in a brand new Shrimp on his rEvo.

I was once with someone who had a CO2 hit. However I don't feel that it was undeserved. I feel that there are many things that are more likely to go wrong.

Has anyone else gone this way?

I like the BOV but also because I have a FFM and therefore it's not heavy for me, I can switch gases by closing the valve, so no switchblocks and always a breathable gas.

I tried the shrimp and the ISC bov before buying and settled with the ISC one. Better in breathing. I have also added a gag strap and that takes the weight away. So great combo for me....

I sold my ap bov to fund buying a shrimp, so Fridays dive was with the standard ap dsv. It was pleasant to use, didn't restrict my view and uses a softer breathing hose unlike the bov does....
Now not sure whether to get the shrimp or not.
 
I used to have a BOV (shrimp) on my Kiss Classic. But on the rEvo I just have the DSV. I like it as it is lighter, simpler and makes me look fearless LOL (joke).

I'll be running a reg (off onboard dil) on a neck bungee soon and using that as an intermediate step to bigger BO tanks.
 
Like OP, I like clean, and as little moving parts as possible to fiddle with. I dive a Meg eccr as stripped down as it can be. BMCL's, DSV, and MAV's, no ADV. I have a shut off on the DIL MAV but rarely use it. Bail out is necklaced. Clean and uncomplicated.

I'm amazed at some of the plumbing configurations folks use. But, c'est la vie, I guess.

No BOV and No ADV but a slide shutoff on dil MAV? So you have 2 ways of turning off one failure point? If you had to turn off the MAV why would you still need the dil tank on with no other means of using it?

That's why I rarely use the slider it's an artifact from a previous configuration. You're right, in the interest of cleaning up it needs to come off. Thanks for pointing it out, I'll get rid of that failure point right quick like!

You are free to leave it on there it was just a question. Whatever works for you.

Of course I'm free to leave it, I'm just glad to have it pointed out. I was being sincere. Unfortunately text doesn't adequately convey tone or nuance.

I have dived my rEvo with the standard DSV since new. Nearly a year ago I bought a Shrimp & it is still sat unfitted in it's box !

Hi Colin,

I wonder if rEvo divers have less to fear?

I see the main reason for a BOV is CO2. Given that the rEvo has split scrubbers, I assume that the chance of breakthrough is much reduced.

On the other hand, i might be entirely wrong?!
 
Hi Andrew
Hope your keeping well. I was stupid enough to have a Co2 hit on my Vision. Having switched to the rEvo I must admit my feeling is that if I am stupid/unlucky enough to have packed 2 scrubber cans wrong & not recognised any warning signs then probably nothing could have helped me that day !
Hopefully see you mid July .
 
Absolutely..... To each their own.... There are many high value reasons to have a BOV. Many more than just a CO2 issue... Some people dive with bailout.... Some choose not to.... Over the last 12+ years I have been diving a CCR, I have had to "bailout in anger" as I like to put it a number of times. With out a doubt it is saver and easier to do it with a BOV of some type....

Saying "I don't and or have have stopped using my BOV because I have not had an issue to use one" is like saying, I have not had a car accident so I don't think I need to put my seat belt on... :poke:
 
Peter,

I have gone the same route replacing the BOV with the ISC DSV & ADV on OSCL since completing MOD2

A BOV (Shrimp) is intrinsic in my bail out plans to either OC or SCC as it is fed by multiple gasses on demand and is supplied by useful quantities. Frankly, I've never subscribed to the premise of "a couple of sanity breaths". Great in practice but in a major situation and in a task loaded environment I want gas, plenty of it and now. If my BOV goes belly up, I just nose breathe the same bail out gasses from the TX100 which I can do at any stage, on demand. My JJ CCR CE DSV is usually included in my dive spares but only as a dive saver should the Shrimp play up, which reminds me that its overdue a service...

I wouldn't like to partially flood one to test that...
