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

My second Garmin. I use this to find reefs in the Fla Keys, with its preloaded maps, it shows almost all the reefs and wrecks. I've used this at night as well, and when it showed a channel marker it was right on the money. Very important for night navigation(lol). I would definitely recommend this product. I use this at least 2 times a month year round in south Florida, and usually go about 15 miles or so offshore every time. I previously had the Garmin 431s, but for a few extra bucks, the 441s has the offshore maps preloaded. Good luck

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.
