thanks for posting this Lysie.. Interesting video.. I left a remark at his offering
My Josy was a trained cadaver dog and was good at underwater. She only did fresh water and was mostly used in streams
Her team out of Clyde ohio was the one that located the body of the little girl in Fla that was in the garbage bag several years ago. Josy was not along on that trip but talking to the other handlers it was a frustrating search as the dogs all knew where the body was but the sheriff in charge of the search would not let them go into the wooded areas as he said it had already been thoroughly searched. As it turned out the childs body was put there after the search was done in that area not too far from grandparents and mother’s home

IMO, never underestimate a dog's instinct.
