Working in fast moving water

PSD?

One other thing I may need is rebreather training to keep from spooking fish as much.  Hookah would be another option.  Some of the programs will be out in the boonies of Alaska, so scuba air will be scarce.  And I'll probably have to worry about bears as well.  Don't want to be grabbed by a bear thinking I'm a salmon.
