Differences amongst sonar units
 

The target in the image (a small boat off Lockes Island) shows the difference of image quality between my Humminbird 1197 and the Edgetech 4125. If you know much about sonar you will know a comparison based on capability is absurd. But the difference is telling nonetheless. Same wreck, same direction of scan.

All of the vessels I have found in Winni on side scan sonar until recently were done with the Humminbird 1197 so it still delivers and I wouldn't be without it.

Absolutely Remarkable
 

I am totally impressed with the quality of the images produced by your "new toy".

Try zooming in-mouse click or whatever you need to do to zoom and blow up the image. It's pretty useful too.

That's absolutely incredible. It's like going from a little 1950's, black and white television. To a 2013 HD 3D TV! I bet the price wasn't 1950's either :)
