Maptech offers boaters and fishermen a handy waterproof chart that features GPS lat/lons for most major aids to navigation, so you can merely "plug in" a destination and head for it. Also included are launch ramp locations, wrecks, fishing hot spots, course and distance calculations. The "flip-fold" format allows you to spread it out full size (24" x 36") or keep it folded and flip to your favorite area. Over 90 charts from Maine to the Pacific Northwest are available (see their website for exact coverage), and they are priced at under $20 each. Maptech, Amesbury, MA; (888) 839-5551; www.maptech.com.
