I'm still getting use to this Helix Mega and I don't use the DI a whole lot. I was in a deep area on the river and wanted to check out the drop offs to see what if anything was holding on the bottom so to DI I swapped. I personally don't see any fish on the screen, but I could be wrong but I was blown away by the definition this unit shows.

Also, the image was much clearer on the screen than it shows in this picture. I forgot and left my SD card stuck in my laptop at home and had to resort to taking a picture of the screen with my phone.
