BOV Use Poll

Solitude Diver

Not sure how to vote at this point. I suspect after researching a bit longer I might be swayed, so I voted for future use.

I do agree with the idea about breathing out of your nose to reduce the CO2 in the loop, but as others have mentioned, the diluent bottle may not last long enough for your breathing to comeback to a level in which you can go to bailout. I like some of the ideas of being able to connect bailout cylinders to BOV.

I am pretty green with my unit, but want to plan for future deep/wreck diving. The risk for O2 breakthrough seems higher in that field due to the depth and likely added work load, and I am thinking I might want to be more protected.

One thing I would like to know (as a newbie), when diving my unit I feel a pretty good pull on my mouthpiece with the normal loop, that makes my jaws pretty tired after an hour or more of diving, to the point the mouth piece at times almost slips out of my mouth (and has for a split second on occasion). Not sure if an adjustment will cure or not, but am pretty certain the added weight of the BOV might just add to that problem. Maybe I just need more time to get used to it? I’ve only got about 30 hrs in on it.

Thoughts or suggestions to cure the pull?

With Golem BOV, and completely relaxed jaws, mouthpeice stays firmly in place.

If rapid removal is needed, easily done.

The only time there is pull is when hanging in a stiff current and looking downstream. Lost a mouthpeice once like that. Good thing I had the extra 2nd stage on the B/O tank.

I used to have hose covers, but took those off cuz they tended to pull the mouthpeice out. May need to re-consider this when I move to the colder climes.

I would consider cutting a couple of inches from each hose. This will reduce the big loop coming from the t-piece. If you do this, you may not need weights at all. From there it is a matter of adjusting the hoses so that the DSV doesn't pull up or down. You can also angle your t-pieces outward a bit which will pull the DSV toward your mouth. You shouldn't have tired jaws at all.

any idea when it will be available ?

Thanks

I checked it out. Thanks. It might help. Even if not for the fatigue, I do like the thought of it staying in mouth in case of unconsciousness.

Thanks, this is more along the lines that I was thinking. There must be a way to adjust, as it does not seem normal. I really have to bite hard to keep it in place.

My buddy and I got two of your BOV's and we absolutely love them.

From what I heard the APD BOV is undergoing testing now and looks like a April release...please dont quote me or send nasty grams in 5 months.

Now to add to this debate from an uneducated standpoint...

Assuming you have adequate off-board bailout with a reg attached, I think the BOV is worth it.

As already stated, I like it that if the caca hits the fan you can switch to it immediately, know your breathing life sustaining gas, compose yourself and then switch to your off-board. I realize there are many options with off-board/ plugged in etc..but you get the idea.

With that CO2 hit video most of us have seen, a BOV would not have helped this guy. I always thought that once switched to OC that the affects of CO2 would go away in time for you to abort the dive...but this is just not the case. Even those his buddies were slow in their responses they saved his arse.

I think the post that hit the money was the one that said...if you have a caustic cocktail you have to get off the loop BOV or not...so what is the harm in the BOV?? And yes the negatives were listed, but I think its hard to turn a cheek to a quick and easy way to get a breath off the loop.

Not had time to read every reply so, sorry if I repeat earlier comments.

I dive with a Jetsam KISS BOV and one real advantage I see that I don't hear talked about much over a standard DSV is that you can get a breath off it at any time. So if your on the surface and it gets rough, you can stick it in your mouth and breath, no lever movement or twisting needed. Once you've got that breath you've bought time to switch to CCR.

Great if your taking your unit off to get into a RIB, or if you were to slip and fall in.

Had the same problem, so when I fitted my BOV, I reduced the hose length until I had a comfortable fit. It made a big difference; there is almost no pull now.

Personally I'm going to pass on the BOV.

It onlty takes about 3 seconds to do a dil flush, and then maybe another 5 to go OC. IF you don't trust the loop you should stay off of the loop. Besides the BOV's currently offered are heavy, increase jaw fatigue on long dives and they tend to have a higher WOB.

If you maintain your equippment, do a pre dive check list and proper gas management there should never be a reason to use a BOV....

Just my thought, but to each their own.
