I just bought a Riffe C-0S today (impulse buy) and when I came home and was looking at the Riffe site it looks like it should include 3 power bands. Am I right? Mine came with two 9/16" X 15 bands. Where would you clip on the third band? Does anyone have experience with the gun. I do most of my diving around the Channel Islands here in Southern California (kelp and rocks) so this gun looked right for my situation and I've always heard good things about Riffe guns. Thanks!
