I find it works well to build a route of fishing spots in a specific area. For example, I have a route called North Slate Island which includes all my spots in the Slate Island area. Spot hopping becomes a cinch with this kind of information. Another good use from the fishing perspective is run the 20 or 25 contour on an off shore hump, placing icons denoting the layout of the structure as well as marking the spot on the spot. And believe me every structure has a spot on the spot, you can count on it.
Key points are the inside and outside turns, the extended points, and the sharp breaks.
Hazards Last but not least is using the GPS to mark hazards. Each time I visit a new area, I seek out the hazards and enter them into my Global Map 2000 as a waypoint. These areas are prominently displayed on my map screen and give me confidence to run safely in areas that I have limited experience in. I would offer that keeping off hazards is probably one of the most important uses of the GPS for me. Join Walleyes Inc .
