As part of our ongoing product enhancement efforts, we've just released another 28 lakes in South Dakota. This means even more places for South Dakota anglers to find new fishing spots and start reeling in big walleye, monster muskies, toothy northerns and colorful trout bass!
Most South Dakota lakes, including Oahe and Francis Case are already mapped! In fact, any lake can be charted in 1 ft HD contours. Whenever our customers submit sonar logs, either by uploading directly or while creating their own maps in real time with SonarChart™ Live on plotter or mobile, we process that data to generate newly detailed SonarChart™. All Navionics products include one year of daily updates so our customers can always have the most current charts!
Customers with an expired chart updates subscription can renew it online for as little as $99 and download the new content. Otherwise, any compatible chart card, from Navionics as well as other brands such as C-MAP, Fishing HotSpots, Garmin, LakeMaster, Lowrance, Magellan or TrakMaps, can be used to activate Navionics Updates card.
