Free GPS Guidance

We got a call recently from someone wondering whether he would be able to use the existing transducer that came with his boat with new GPS fishfinder combination.  That opened a conversation about compatibility.  Not all brands of ducers will be compatible with all brands of GPS fishfinder combination.  You really want to do your homework on that one to be sure that you have the correct match.  Also, his old fishfinder was set into his boat, permanently affixed; and he wanted to be able to drop his new model into the same slot.  We did the homework and found the GPS fishfinders that would meet all his criteria.  That was an interesting exploration, but we found some great options that would fit perfectly.  During that search it brought out the fact that, although some GPS fishfinders will work permanently affixed to the boat, some will actually get much better reception and give you better screen visibility if they are on a swivel mount which gives clearance all around.  These are all important things to consider when shopping for a replacement GPS fishfinder combo for your boat to give you the best fishing possible.  Happy fishing, and I hope you catch the Big One!
