Our laminated charts are placemat size (11x17) and fit perfectly in the radio box, or under the seat of most boats. They are very durable as we use a 5 mil laminate instead of the 3 mil found on other charts. They are colorful, to scale, and provide details such as water depths, Nautical Mile radiuses, and a compass radius which is offset for magnetic deviation. This safety feature allows the angler to do a 180 degree reverse in the event his electronics fail. Each chart features the fishing spots in both Loran TD's, and Lat/Lon. Depths, ranges, and bearings are calculated from that chart's port of departure (Sea Buoy). The fishing coordinates are separated into various types of structure. Each chart contains approx 100 spots - using local names in every case possible.
