Cressi Back-jac bc

[red hook]

Hey Guys....
I just purchased a cressi back-jac bc and a catalina aluminum tank, aftre soaking the
tank strap on the bc, and tightening as much as possible, I still seem to have problem with my tank slipping in the strap....any suggestions?

Double check the way that the strap is threaded through the buckle; sometimes they aren't threaded the right way at the factory. Also, if the end of the strap goes through the end of the buckle, give the strap a sharp tug and hold it while you close the buckle. The buckle should make the tank ring when you close it (at least in my world). I've never soaked my BC before putting a tank on and never had a tank come loose on a dive
