C-MAP Insight Pro ($99) and Lake Insight HD ($169) combine chart detail, content and C-MAP cartography with data from GoFree Lake Insight charts. Data from the Insight Genesis Social Map provide views of underwater contours and lake-bed features. Insight Pro shows high-definition, 1-to-3-foot depth contours for lakes and other bodies of water, plus a custom color palette for depth ranges, state fish and wildlife regulations, and lake-specific fishing tips. Offered initially for Lowrance, Simrad and B&G displays, the cartography will be available to Raymarine and Furuno users. C-MAP, (800) 424-2627. c-map.com
