Looking at buying a GPS for the boat for the upcoming season. Hoping to get out on some new lakes and think it would be helpful. Was considering going the handhelp GPS route to save money since I already have a basic fishfinder. Any suggestions on which handheld units work the best for fishing? Looking for something that can plot points and keep me from losing track of the boat ramp. Also not looking to spend several hundred dollars. Definitely on a tight budget but have some gift cards that could lighten the blow. Thanks in advance.
