Hey guys im looking at getting a new fishfinder and was wanting one that you can hook up a handheld GPS to. I dont have a lot of money to throw at it so somewhere less than 300 dollar range is where im at. I asked humminbird about the 561 an they said you can hook up gps to it but i cant find anywhere on there sight or anywhere else for that matter that says you can. Just wondering if anyone on here has done it before, or has any suggestions.
thanks in advance for the help
