Costumer 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.
Not bad just a little hard to set up the different screens on it.
But with nothing added right out of the box you can do quite a few things it has a tracking thing it has a speedometer and charts of where you are going and where you have been it has a chart plotter a man over board maker a track marker quite a lot and it does quite a bit without adding the transducer or antenna or any of the other add-on's it is easy to wire up to the boat there are a lot of wires when you open it up and it scared the crap out of me they were maybe 20 or 30 wires but do not worry you only need couple of them A Positive and a ground and thats pretty much it for the basic operation and like I said you really get a lot in my opinion..
