Did you by chance compare 800khz to the MEGA? There is definitely a big difference in the 455 and MEGA. The right side of the MEGA image begins to darken about mid way across and would tend to look like a downward slope when compared with the G1 image.
Just thinking out loud. The others do look much better than the green. You def don't see the same behavior with the green shots in 455. The amber on the first page are def the best shots so far. Either way they are all better than anything else on the market right now, but anything can always be better. Never stop pushing or they will stop improving.
Examples with a different pallet than green. These may just be shallow to deep shots with sensitivity too low? I'm just hoping for a little more range with the mega. These are from Bill Carson on Lanier. Def not the quality images we are used to seeing from him
My friend Bill Carson got these cool shots yesterday of dolphins by the boat and redfish by a bridge while we were in Destin, FL for the Bass Pro Shops associate training seminars with the new Humminbird Helix Mega Imaging. #flipper
