Still not seeing much other than the fish in the water column. Even though when going over a known school they show up perfectly in the water column but no matter what setting I use or color, they don't show up in the lake bottom section. I didn't try the 800mhz but from others posted pictures and the numbers of crappie that was on this suspended pipe I was fishing.... I should be easily seeing them... but I'm not. Even zoomed in to 45 feet only fish in the water column. Not real happy with this 'bird so far.
