Fish-N-Map Company underwater topography maps are printed on a
waterproof, tear-resistant material and are folded to 9" x 4". When opened, each map is approximately
3' x 2' in size and is printed on both sides. These maps feature waterproof plastic "paper"; underwater
depth contours; fish locations; latitude and longitude for GPS; often multiple lakes on one map; boat
ramps; recreational facilities; and much more.
