I am way behind the times when it comes to technology. My idea of a waypoint is lining up the willow tree on one shore with the brown boathouse on the other...good luck on a foggy day! This summer I discovered what a great tool a GPS can be. While navigating at night on a foreign lake, my buddies hand held unit got us where we needed to go. To rely on eyesight was impossible. No way could you see where channels were between islands. Anyways, after a lengthy search, and lots of input from folks here I have decided to go with the Lowrance Elite 5. Basically a money motivated decision as its a "lower" cost unit, but from what I've heard, a decent unit. Thanks to all for your input, and especially scugog who has answered all my rookie questions without frustration.
