I started a series of Side Image and Down Image scans on my Blog to try and teach you what you should be looking for while scanning with your Side Image and Down Image. This one will be of a Flat in the back of a major creek. Hope this help your understand these expensive units.
Take a look at this photo before you scan down to the image below and see what you can find in this Side Image screen shot.
This screen shot side image was scanned in the fall of the year and as you can see there is a lot to be found in the image.
Hope you find these photos useful.
