Tips on starting diving doubles

[SouthernSharktoothDiver]

@SelfDiver As of the moment, nothing much. My dive buddy's been dragging his feet and I haven't had the time to go somewhere safe enough for a solo test (because if I'm testing a new configuration alone, I'm looking for shallow, still water with at least a few feet of vis and no potential problems, and I haven't been near that lately). So, at the moment, the gear's just sitting in my closet. Which is fine, not like it expires, but ideally I'd take it for a spin before the summer's out and try some different configurations.

are quite comfortable

Especially with that OMS 32lb single tank wing

Are those EU only tanks? I've only seen the LP 50s in the US. Was hoping for some HP 5.5" tanks of similar size to get better buoyancy characteristics and more gas, but they seem not to exist

It's 2 yoke connections, tightened with a wrench (knot hand tight on a knob). Plenty secure if you take the few minutes to assemble correctly. Not exactly "a multitude of failure points."
Granted, not as solid as a modern isolation manifold or solid bar manifold, but has 2 advantages... The ability to mix and match tanks without emptying them, and at the low cost of borrowing (free) let's him try double 72s in the water with gear he already has.

Do you mean that you can use 2 cylinders of different capacities using this contraption, e.g. a steel 133 with a steel 120?

Conceivably yes, but I meant more in terms of taking two partial fills (leftovers from single tank dives) to pair up and get another dive out of.

Thanks for your quick reply. Where can this be ordered here in the US? What's it called?
