I saw this on the other site. It looks very cool. I pre-ordered one this morning.

 HotMaps Explorer is the ultimate fishing trip planner that allows boaters to plan, save, download and transfer waypoint and route information between a personal computer and leading GPS plotters.

Derived from the best survey sources available today, these lakes are available in extremely accurate maps allowing boaters to explore bottom contours, structure, drop-offs, vegetation, boat ramps and marinas, to name a few, from the comfort of their home or office.

The lake maps are provided in a very intuitive PC application for viewing maps in 2D or 3D, printing, planning and more.

By studying structure, understanding transitions, exploring 3D views, marking and labeling key spots, and planning routes before going out, anglers of all ability levels can make the most of every fishing trip.

Navionics has geo-referenced all lake source data to provide the ultimate in positional precision, making its HotMaps line the most accurate charts on the market.
