Hello all, noob here with a new 597 DI on its way to me. I have been doing lots of reading online and the Humminbird manual for the 597 di. I am unclear how to interpret the Images below the bottom. It appears that when you see SI images next to DI images that it is showing you a what is to the side of your image on the bottom. Here is an example
http://forums.sideimagingsoft.com/index.php?topic=1617.0 you can see the ditches going down in the DI image but I am assuming its showing them going to the side.
So how do you interpret that? Is it showing one side or the other from your boat? I guess I am trying to figure out how you get some type of depth perception of the bottom. Where the traditional sonar shows you how hard the bottom is. This appears to let you see down and to the side also.
For example if you see a tree on your screen is the tree directly below you? If so when you see shadows on the bottom image below it. Is that to the right or left of your boat?
here is another example of something showing up on SI then the DI image it appears to show it on the bottom of the DI screen giving you a width to go with your depth? Not sure what terminology to use.
Also if this is the wrong place mods feel free to move it. Since there was no DI only forum I wasn't sure where to put it.
