I upgraded from my FL18 to a Marcum LX7. WOW is all I got for it, I like being able to fine tune it to my liking. I was fishing perch last weekend and could tweek it so I would be able to see on the screen if my minnow head got snatched!
On the other hand I did buy the new digital depth/battery gauge attachment for my FL18, my wife or daughter uses it when they tag along.
