I just recently upgraded from a flx18 to a 28. I used it for the first time this weekend but only fished in less than 10 feet. So far I'm not really liking it too much, my bait looked so huge on the screen and the gain was at 0. I played with all the settings, I really could not figure out how to make it any smaller. The other thing was the digital depth read out. It showed up and then the depth kept jumping by 1 or 2 feet. Sometimes it was consistent jumping and really i couldn't tell what the actual depth was. It was only my first time using it, I'll give it another shot before I decided to keep it or return it. I'd just like to get another opinion from somebody else that may have it and what is thier expierence so far.
