When scanning the lake bottom with your Side Image unit regardless of what brand or model you have to get the best images requires the correct angle you scan from. In the images below I have images of a side scan with a Humminbird unit at different angles to show you what I mean.
In the image above the boat is on the right side of my boat and I’m heading up river. And as you see that I almost ran over the top of the boat by looking at the top left corner of the boat with my boat.
In the image above you can see that I took my boat over the very top of the sunken boat with part of the boat on the right and the left sides of the scan. By the way can you see the Bluegill beds in the sunken boat.
In the above image you can see I got the correct angle of the sunken boat and you can see the entire boat and the details of the boat.
Look at the above image and you can see I got the angle wrong.
Here I have the boat and chart speed wrong for the best scanning image.
Now in this image you can see it all came together with the correct boat speed, correct chart speed and the correct angle. I’m on the inside shallow side of the boat scanning up river at a slight angle to the boat to get the best scan of the boat.
So the next time you are on your lake and spot something, try scanning it from different angle and speeds to get the very best image of what you are looking at. This all takes time on the water with your units and playing with the settings.
