I just bought a Minn Kota Powerdrive autopilot/co-pilot trolling motor and have heard that a portable gps can be used to gauge speed while trolling. I have a Lowrance console gps unit but don't want to have to change the mount then turn around to see it. Buying new gps for the front or the i-pilot is out of the question right now. Can somebody recommend an inexpensive hand-held gps that will serve my purpose? Thanks.
