C-MAP, a leader in digital marine cartography and cloud-based mapping, announced today the release of the second offering in its series of digital fishing map cards, Precision Contour HD Tennessee.

After an extensive survey campaign by C-MAP staff, the new card features highly detailed 1-foot contours, high-resolution satellite imagery and C-MAP's one-of-a-kind Custom Color Depth Shading, as well as fishing and navigational Points Of Interest. The card is exclusive to chartplotters in the Navico portfolio of brands (Lowrance, Simrad and B&G).

The C-MAP survey fleet includes shallow-draft boats with surface-drive motors, enabling comprehensive coverage of every popular and important fishery in each state covered. Surveyed coverage includes most of the skinniest distant creek arms and shallowest backwaters, as well as key, fish-holding offshore structure like humps and holes, reefs and shoals, ledges and breaklines, sunken islands and points.

Precision Contour HD charts also feature C-MAP's Custom Color Depth Shading* functionality, which enables anglers to highlight specific areas of interest, including current fish-holding depths and potential hazard areas. Custom Color Depth Shading also enables adjustments to the chart display to reflect high- or low-water conditions that can affect the shape and edges of shorelines and submerged or partially submerged structures. Additional map-display features include four pre-set, depth-shading palettes, including Safety Shading.
