Mapster

Satellite overlays for Lowrance fish finders

See the whole dam before you cast.

Mapster brings satellite imagery of your dam directly to your compatible Lowrance fishfinder. Simply load the map onto a microSD card, insert it into your unit, and see your boat's live GPS position overlaid on the imagery - helping you explore the dam and plan your next cast.

What is Mapster?

The dam itself, on your chart

On most fish finders, our dams show up as little more than a blue outline with nothing inside it. A Mapster map fills that outline with high-resolution satellite imagery of the actual dam, prepared as a chart overlay for your Lowrance. The points, bays, inlets and shoreline you'd see from the air are right there on your screen, and your boat's GPS position moves across the picture as you fish.

The map lives on a microSD card in your unit, so it works without cell signal out on the water. Download it and copy it onto a card of your own, or add our SD card at checkout and we'll post it to you with every map on your order already loaded.

How it works

From your basket to your Lowrance in four steps

  1. 1

    Choose your dams

    Add as many maps as you like to your basket, at R750 each. For water we haven't mapped, send a custom map request.

  2. 2

    Pay on PayFast

    You pay in rand on PayFast's secure page, so we never see your card details.

  3. 3

    Get your download links

    Once PayFast confirms your payment, we email a download link for each map. If you added the SD card, we post that too.

  4. 4

    Load it onto your unit

    Copy the map onto a microSD card, put it in your Lowrance and choose the map from the chart menu. Menu names vary between models.
