We still have our first boat, a 14' Sea Nymph and plan to start using it more often and looking at entry level fish finders like Garmin Striker 4, Raymarine, Lawrence 4, all about $100, mainly to check water depth in the canals and help friends and relatives to find fishing spots around Charlotte Harbor and just as a round about to the local water side restaurants and tourist hot spots. Any recommendations? I just don't a high end model and if folks get lost, they can call or use Google maps
