I purchased a hooka afew years ago. Bought a used 16' maritime skiff with 70hp yamaha. I have soo much fun with this rig. Found quite a bit of gold hitting popular bay areas and taking 1 week trips once a year to lakes. I don't go any deeper than 10' underwater. I use the hookamax 12v 2x50 which is 12v 2 divers 50' hose each. I bring 2 big deepcycle batteries but never had to switch over as 1 lasts about 3 hrs. I use an Excal for salt water, at pro, and detector pro underwater for fresh water.
