Backmount

This list is meant to give you a head start on getting what you need to do dives in a backmount doubles rig I’m pretty sure I remembered everything, but when you’re getting your rig together, ask lots of questions!
I know there seems to be lots of “small parts”. Not to worry! One of the things we do in the Discover Tech or Tec 45 class is put it all together… together.
