Learn how to:
1. mark a waypoint,
2. page to the map view so you can see the mark, and
3. zoom in and out.

When you get these simple operations under control, you've mastered the single most valuable GPS technique--returning to brushpiles in blind locations. Everything else is gravy.

After getting comfortable with the handheld unit, you're going to discover that Garmin's "base map" for this product sux. It has far too little detail. After a few months, I bought the "Topo U.S." map CD. I would have gotten the marine product, but it included very few of the small lakes I fish often. Topo, on the other hand, provided good detail about the back roads leading to obscure destinations.
