looking to get a fishfinder for the yak this spring. not looking to spend a load of cash on it. have narrowed my choices down to the humminbird piranhamax series. my question is... do i go with a portable that has a suction cup transducer or do i mount the transducer in the hull. i mainly use the yak in the ocean. my worry with the portable is wires over the side and getting in the way and potentially damaging suction cup transducer when landing yak on the beach.... your positive/negative thoughts & comments are welcome and appreciated...
