I didn't expect much for the price I paid, but was pleasently surprised. The screen is very easy to read, and the automatic features actually work without being fine tuned. Far and away the nicest feature about this unit is the dual beam transducer. It has great accuracy not only under the boat, but off to the sides. Lastly the option of mounting the transducer to the trolling motor without having to buy an adapter was icing on the cake.

This is a very good fishfinder and depth indicator. But despite the name....IT HAS NOTHING TO DO WITH GPS!

This is just a fishfinder.
