The LakeMaster® brand was purchased by Johnson Outdoors in 2011 and LakeMaster® Digital GPS Maps are now only compatable with Humminbird® products.     See videos on our various cartography products on our youTube channel.

Beginning in 2011 some of our color combo products in the 300 and 500 Series products are also compatiable. 

Humminbird® products are not compatible with older/existing Lowrance or Garmin maps.
