I just got a new Lowrance HDS5 so I now have for sale my 2007 Humminbird 747c. This is a very nice unit that is color, 4000 watts power and has the weather sense monitor included. The only reason I am selling this unit is because it is not true GPS. It is GPS capable, meaning you can get a reciever but as a track plotter only. Basically it will show your speed, trail to and from and waypoints. If someone wants it with GPS it would be perfect for river fishing. With the weather sense monitor, I have over $500 invested, asking $350 or best offer. Thanks for taking a look. If interested send me a PM.
