UPDATE:
I dove with my new strobe (they replaced the head of my defective one) and I notice there is a big difference in the way the switch works between my new one and the other "old" one (bought in January).
The new one has distinct "clicks" at the off, on and test settings, where the old one just has a mushy feel to them and absolutely no click stops at all. I am guessing that something has changed in the manufacturing, or that something wasn't right on the batch I got. I am hoping that if the other one fails it does so in my warranty period. The newer one feels much more solid.
On the bright side, once I figure out how to get this rig to really work, I think it is going to let me take some really good pictures... that's MY learning curve, as long as the equipment is physically functioning all bad pictures are on ME, not it.
Yep, I know exactly what you mean. Being new to the UW camera scene, my last batch had a lot of overexposed pics. I found these tips on the Sealife site. Just thought I would share if you have not yet seen this.
