  • 1-Foot HD Contours – Comprehensive precision 1-foot-contour coverage on the most-fished waterbodies in the state
  • Custom Color Depth Shading* – Custom color palettes allow highlighting fish-holding depths and hazard zones (16 color options; 10 customizable depth ranges). When displayed in a compatible* sonar/GPS unit, the maps on this card can be customized with Custom Color Depth Shading. Select from 16 colors to highlight as many as 10 customized depth ranges. You can set two separate custom-color depth palettes for every map. Fish-holding structure will be much more visible when set apart by Custom Color Depth Shading. Custom Color Depth Shading also enables adjustments to your map display to reflect high-water or low-water conditions that can affect the shape and edges of shorelines and submerged/partially submerged structure.
  • Satellite Imagery – Locate docks, piers and other man-made structures that attract fish. Transparency of satellite image can be adjusted to display more or less of the chart’s 1-foot contours overlaid atop the aerial image.
  • Fishing, Navigation & Safety POIs – POIs include: Fishing HotSpots waypoints (with lake-specific fishing tips); submerged fish-holding structure such as old road beds, creeks, ponds, bridges and building foundations; navigational aids such as channel markers, hazard areas, etc.
