Garmin GPSMAP 421 4-Inch Waterproof Marine GPS and Chartplotter Reviews

If you are looking for a compact, user friendly GPS Chartplotter/Sounder; buy this one. Garmin is the best, most fairly priced plotter/sounders available. My only regret was not buying the 541s. That 1 inch make a difference. I've been on the water ny whole life and for the money the 441s and 541s are the best plotters available. Amazon has the best prices on them too. WOuld have recieved 5 stars but add and tech infor doesn't state how long the transducer wire is. I took a chance and it fit with some room to spare. Transducer wire is 25-30 ft long. I also recommend buying the transducer with speed and water temp.
