How much extra weight do you need to dive with your PFD? Do wear it over or under your BC? I noticed in your profile pic you are all suited up, within 10' of the water, and NO ONE is wearing thier PFD
If we were selling shirts side by side and for the same cause, who do you think would sell more shirts?
You have a point, but if you look closer, the one closest to the water is suited up while the gal and I are about at that 10' limit. The rest of the team are fine. Besides it was a controlled photo op and not training or an operation.
As far as selling the shirts it depends on which area you'd be in. People tend to support the "local" team.
