Discover the industry's premier freshwater fishing maps, Garmin® LakeVu® G3® Ultra Maps Data Cards. These Garmin map cards set the standard in coverage, clarity, and detail for more than 17,000 lakes with up to 1' contours. Integrated Garmin and Navionics® data with Auto Guidance use your desired depth and overhead clearance to calculate routes and show a suggested path to follow. High-resolution relief shading combines color and shadow to give you an easy-to-interpret, clearer view of bottom structure than contour lines alone. Depth Range Shading provides up to 10 depth ranges, letting you view your target depth at a glance. Shallow-Water Shading allows you to use shading to designate the shallow-water depths you need to avoid. Dynamic Lake Level lets you adjust your maps to the lake's current water level to have a better idea of spots accessible or too shallow to explore. Unique 3D views including MarinerEye and FishEye provide additional perspective above and below the waterline. Garmin LakeVu G3 Ultra Maps Data Card steps up your boating like never before, so you can enjoy the water like never before.
