Heck, if I had those images to fish with I'd be happy! Can't wait to get the Helix mega 10 on boat but I'll have to stick to the old 998c to show me what's down there! My pontoon has the HDS 7 structure scan and it's pretty good if you are willing to fool around with the settings. But it's done it's job and I hate to mess with it once you get what you think is the best readings. Thanks for sharing your findings.
Keep us informed!
