Guys I've been detecting 12years now the last five underwater (scuba), I've used a Garrett Infinium,Whites beach hunter,Fisher cz,and current Garrett Sea Hunter.Ive dived with them all been neck deep in the ocean,waist deep,they all handled the water well but they all looked old and beaten up after a while,even after every use I rinsed them all.I also own a SDC would I take that in the salt water NEVER.
