Bounty Hunter Pioneer 505, Teknetics Gamma 6000, DetectorPro PiratePro, Fisher F-75 LTD2, Berkut-5 (a russian detector) and a good ole original Garrett Propointer that is still going strong.
I have loaded many cargo ships like that in my time. Used to see dolphins in the Mississippi river gulf outlet (MRGO) a lot. They are really smart and fun to watch. Thanks for sharing them.
