How about yall start a new thread since these lengthy descriptions are hi-jacking the purpose of this thread....

On your topic... Just use the split screen feature of the Lowrance HDS or the Humminbird SI unit so you can see DI, SI, and 2D all at one time. If you are seeing the same fish in 2D and DI then they are pretty much under the boat if in shallow water or inside the cone degree of the 2D. Then look at your SI to tell which side of the boat.. It is that easy...

Now back to posting Side Imaging Pictures!!!!!!!
