This is an inspection/ salvage dive on a sunk barge in the Tennessee River. I am using an AGA mask (Interspiro) with OTS comms, a ScubaPro semi-dry, the ubiquitous USD Super Rockets and a bunch of weight. Water temp 50 F., depth never exceeded 15 FFW and was completed on 40% EANx. Oh, and vis was -1 foot (eyeball refelctions).
