Summary: This unit seemed to have the best standard lake shoreline maps compared to Garmin and Magellan units I've tried. It is great on batteries and meets nearly all our needs. I'd love to be able to upload waypoints, but none of the inexpensive handhelds allow that.
Summary: I am a newbie to GPS and there is definitely a learning curve. The Lowrance manual that comes with the unit is excellent to getting you started quickly, but you absolutely must get the advanced manual, available on-line at lowrance.com, to really enjoy the features.
