I do a lot of side-scan sonar work using actual side-scan not humming bird.
The frequency and range look decent but I'm not sure how good the unit is. The truth is usually in the transducer. For a few grand it is a lot cheaper than standard mapping side-scan

Side scan itself is not 'true color' it shows the texture and hardness of the bottom or structures on the bottom by bouncing sound waves off. The color is just a scale of intensity. We work in a yellow brown scheme, others are black-white, blue-purple etc...

Look at the side-scan enhanced images and App. D for some examples.
