Aqua Lung back pack help

[Chris Hipp]

I'm having trouble figuring out the rigging on this back pack. It is the same one that the guy in this video is using YouTube - vintage dive at the Sea Tiger

I know I am missing the strap that goes between the legs, but something else feels missing. Does anyone else have this back pack, and if so could you post a picture of how it all connects in the front?

thanks

Here is the catalog view of this US Divers Bac-pac. If you don't get it from here, ask again and I can get some real time photos.

Ok, I see how the crotch strap feeds though. Looks like everything else is there, I just had it rigged up wrong.

Thanks again.

I thought the video was funny. A guy with a double hose and no BC with perfect buoyancy and trim and divers in the background with BC's struggling with buoyancy and trim, hand swimming and pedaling a bike.

I had one of those USD backpacks in the 1970s. I did not like the plastic strap, as it kept sliding off my shoulder.

Note that I'm wearing me weight belt outside the harness; do this by putting the weight belt on last. That way it can be ditched. I say that as the diver in You Tube video had the weight belt under the harness, Sea Hunt style. This is not a good safety practice, and was only done on Sea Hunt because they were constantly changing cylinders underwater during a shooting session (from what I've read). You also need to use the military harness quick release on the D-rings. You get this by threading the end back through the D-rings to form a loop, which can be released very quickly by pulling the end. This is discussed on this thread at the VSS website:

PS--I also enjoyed seeing the vintage diver in perfect balance, and the BC boys struggling.
