    ADV functionality from modified BOV

    wondering if anyone has experimented with poking a hole in a BOV barrel so that when in closed circuit, neg pressure would still trigger the BOV's 2nd stage?

    I know Poseidon's BOV is designed to do this, but with some proprietary gadgetry.

    I guess the risk would be also allowing your exhale to escape through the 2nd stage exhaust, but if the physics worked out with loop positioning, this would be a feasible, yes?

    I think your "hole" would need some sort of directional check valve to only allow gas to flow into the loop but not be able to vent.

    You could simulate this by slightly cracking open the BOV. What you will likely find happens is the BOV freeflows into the loop continuously and you vanish in an upwards direction.

    somewhere out there, I recall a few BOVs doing this. I know the Poseidon has this feature, and the Apoc claimed this also.

    There was another unit, but I dont recall which....any guesses?
