LakeMaster Contour Elite is a PC compatible software that allows you to pre-fish your lake while in the comfort of your own home or office. It is a great companion tool to the digital GPS map. You can create, import, or export waypoint information to compatible GPS units, backup your critical waypoint information, keep detailed fishing logs, view your lake in 3D, print your custom maps, and let Contour Elite search out specific fishing locations for you.
