Dive Rite No Mount Tank BC question

[Ulfhedinn]

Looking for one that is $100 or less or an alternate option. I will not be doing tankless diving actually something for a instructor for his classes. Will post once I get it all dialed in.

Dive Rite - No Mount Tank BC

The No Mount Tank BC is designed to provide added buoyancy to heavy steel cylinders or other equipment underwater. The BC attaches to the cylinder via a center-mounted 1.5 inch cam strap (included). Each end is held in place with two adjustable 5/16 inch diameter bungee straps. The BC is...

Good luck in the $100 or less. Maybe you can find a used one but the SiTech Slide inflation valve is around $100 on its own. Add the OPV and the costs start adding up…

I'm gonna go with this (below) and a couple old cam bands (or stage bands if the tank is rigged that way) as worth a try:

Hog SMB Safety Sausage 36in

Choke the top of the SS under the upper band to keep it from flopping. Bring it down and under the lower band.
Fold the sausage up and attach the "bottom" at the neck using the d-ring.

Probably not enough for a water heater, but I imagine it would certainly handle a neutral(ly weighted) AL80 since you are only talking about about 6lbs negative max.

I'm guessing on the specs from similar items since it is not listed , but an An 18" long, 4" diameter cylinder is about 226ci, a gallon is 230ci - CEfGW (Close enough ...)
Gallon of water is about 8lbs so you have about 2lbs of buoyancy for the reg.

No push-button inflator, but easy enough to add a BC hose to the onboard reg for push-on-filling and it has an OPV for filling or surfacing safety.

Ghetto dive engineering.

Rig old wing with 1/4 bungee cord.

If you have slotted wing, could use tank straps.

Hell, you could do manifolded steel doubles with a wing and a beater plate.

I didn't even notice it used that. Good call... Makes me think there might be another way. At least a less expensive option.

@grantctobin Shared this idea.. Trying to keep is simple but that is never really the case in the end.

I built I rig with the deco sidemount bladder. Works ok for a pair of 72's or al80's in a 5mil. It is amazing with a pair of al40's. Like diving with nothing on.
