Newer Maps from $19

These satellite maps only work on your Lowrance, Simrad B&G sounder. ( But not Hook or Eagle versions)

You can add as many maps as you like to your micro sd card whenever you like. Please view "installation" tab above for tutorials & instructions. Please also join our facebook page for tips & future map updates.

The general Satellite maps are better resolution so you can see what remote river or creek you are up as the waters usually uncharted by the big names marine chart makers.

The Red Low tide maps are more recent & more current for sandbar location but lower quality resolution.

Why "red"? because it contrasts the muddy water from the muddy sandbar.


For those with the big name brand map cards," just try" one general satellite map download of your favourite river system, I know you will be surprised. You can add more maps later.

Garmin & Humminbird users, I am sorry we cannot assist with maps for you. Different machine formats and locked in to subscription based maps.

About Top End Maps

The Imagery is made by someone who never wants to be stuck again on a sandbar 8kms from the Mouth of the Roper River NT late afternoon into the night for 5 hours with nothing but high tide tracks on the chart plotter all heading over shallow water & sandbars. For those that have been in that lonely situation, or stuck on a boat with a packet of chips & with your inbred Cuz's , you'll know the importance of the Lowrance Chart Plotter maps we have here on this website. They are not designed for Humminbird or Garmin Fish finders.
