Something I wish I had done when I first started diving and bought my first set of gear is rent some of the different styles of the big ticket items. For instance I probably never would have bought a jacket style BCD had I rented and tried out a wing first. Same for my reg. set and computer. On the plus side after upgrading and replacing key items I have started to assemble a complete second set of gear for back up and/or for taking a buddy who doesn’t have their own.
