I have a Lowrance Elite 5TI with TotalScan. I purchased a dummy off Amazon (Plastic), drilled holes in it so it will fill with water and sunk it in around 4.5m of water.

Using the sidescan, I was hoping I'd be able to see an outline of the "body" in the Reefmaster Sonar Viewer/Reefmaster sidescan mosaic module but unfortunately, it does not appear to be visible. I've found a number of other objects, such as sunk boats, concrete blocks, trees etc - some of which are of a similar scale.

Does anyone have any suggestions? Is it because the dummy is fulled with water and does not represent a change of density from the ambient water or do I need a better sonar unit?


Any input is greatly appreciated!

Some plastics (PVC, etc.) have a similar density as water so they don't show up well on sonar. Try using a different material.

As mentioned, you need something that has a different density then water.

Using a (dead) pig is probably the best way to train personell for SAR with sonar. Might want to clear that with the local authorities first though, so they know what is going on when people start calling them saying there is «a man drowning pigs in the lake». ;)

Fill it with sand or pea gravel so it has some density to it

We filled our dummy with foam.

Did you see the dummy on your sidescan sonar. Is it is not there, then you'll never find it in Reefmaster.
