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. More >

I bought this unit thinking it was a good deal for a unit with a base map included. The map is a blur, and there is no definition once you scroll in. Be prepared to buy an additional sd card to get detailed map information like depth, markers, and even creeks.

The description leads one to believe it has a U.S. base map installed. Unless I'm doing something wrong it has no map what so ever. Be prepared to spend another $99 to upload any kind of map. Yes, it is of good quality. Installation is a snap. Most of us will only use the ground and hot wire. More advanced installation will provide you with leads to your radio and other communication devices. Ease of use is good, you will have to page through a lot to find what you want though. One thing I reall ... y don't like is once you mark your position you have to page forward twice to name it then scrolling through the alphabet characacters is like pulling teeth. Don't get me wrong. I will rate it good for value, just remember you get what you pay for. If I had to do it all over I would spend the extra money for a better model. More >
