Navionics, on the other hand, works with many different brands of sonar units on the market, which is a plus for any angler who doesn’t use Humminbird sonar units. This might be due to some agreement between the two companies, but with Humminbird being one of the top, if not the #1 sonar unit brand used, it works for Lakemaster. Lakemaster map cards are only compatible with Humminbird units.
The compatibility between both Navionics and Lakemaster is quite different.
