Question BOV for Choptima?

[Heat Miser]

What happens if you cannot plug into your off-board gas? Do you have a primary regulator attached to the cylinder?

There is an onboard O2 tank not shown that sits under the scrubber cannister at the bottom of the unit the dil is offboarded.

The QC6 female plug shown in photo, means you have to replace the low pressure inflater hose on the off-board dil, (whether backmounted, staged or sidemounted) with a QC6 male plug. This means if diving in mixed teams you can't necessarily swap stages etc and I know some people that carry a QC6 to LPI adapter in their pockets if this is a concern.

The reason you are unable to locate a specific recommendation is that there is not a recommended one for the Choptima.

I would ask why you feel like one is necessary?
(Please don’t actually answer that as there is not enough time for the BOV/DSV argument.)

Well for one reason (without getting into the BOV vs DSV argument) is that the ADV on the Dvesoft BOV is better than the stock standard one provided on the Choptima.

OP is asking about what BOVs fit onto their rebreather in question. The answer is, pretty much any good BOV is likely to work.

Not for much longer ;-)

I think one misconception about BOVs is that they "add complexity" or are "too bulky."

You already need some open circuit regulators on your rig. Why not put one of them right where your mouth is?

Have you ever considered bungeeing a backup/bailout reg around your neck? A BOV is simpler and less bulky than that.

But you can't donate a BOV. You will still need a reg on a 5(+) foot hose to do that.

Another misconception is that it is not a DSV.

A BOV is also a DSV. Unplug it from a BO gas and wow look, a DSV. Proceed per DSV operations.

Perhaps the biggest safety advantage that few admit is that with a proper working BOV, we are far more likely to decide to breathe a safe OC gas sooner, for any reason that might come up. Because there is zero effort or clutter. Turn knob, figure yourself out, then finish your dive however appropriate. Necklaced regs can almost reach that level of convenience--almost.

OK we will discuss in Oct when you Boom me and my rEvo at Marc's

This is not my unit, but this is a photo of a local guy's Choptima that is set up with the same divesoft BOV and DiveRite MAV i.e. I copied.... bizarrely same photo as @lostsheep so Richard's I guess? Regards Greg

I can say with 100% confidence that pic on the right is not Richard’s chop, unequivocally, that is mine.

What you call a misconception I call the literal definitions of the words complexity and bulky.

I gave it the good old college try so I’m not misconceiving anything. There are more components and a BOV is physically larger.

The BOV is physically larger than a DSV yes

A DSV plus a necklaced BO reg is physically larger still

ding ding ding. we have a winner. Unfortunately I see alot of CCR divers with no necklaced reg. Still lots of people that are convinced they are such superior specimens that they can always locate a reg on a bottle, pull it, and get it in their mouths during a CO2 hit as fast as they can flip a bov or switch to the necklace. Because of course, they have never ever accdidentally manipulated a bottle and the reg get out of its "normal" stowed orientation.

I keep a bungeed reg no matter how I’m diving. Probably not necessary with a BOV, but one benefit of the chop is using the EXACT same configuration as when I’m diving OC.
