HotMaps® Premium
More than 17,000 total lake maps with complete fishing information for your GPS, plus over 1,000 high-definition lake maps featuring exclusive 1' contours from Navionics own on-the-water surveys.
Choose from 5 huge regions
throughout the US and Canada on a media card compatible with your chartplotter.
CF and MicroSD media cards are pre-programmed and ready to use with today's leading chartplotters… just plug-and-play
The Gold Maps are more for offshore.
