While I’ve only had my lx7 for less than a week, I wouldn’t trade it for anything. (well maybe panoptics) it took 5 minutes to learn how to use, and can do more than 90% of flashers on the market. I upgraded from an lx3tci so the possibilities are seemingly endless for the lx7. I thought about a Helix 7 but after doing my research, I went with the lx7. The only benifit to the Helix is the maps. Which I use navionics for anyway and navionics in my experiences is better and more accurate than lake master. Other than that, all benifits seem to lean towards Marcum so I went with the lx7.
I’ve already got about 20 hours of use with the unit and can tell you I have no issues seeing the screen in the sun. I ran the back light at 50% the entire time I was outside and had 0 issues seeing the screen. Granted I obviously didn’t set it so the sun was shining on it allowing it to give off any glare. As far as the depth jumping around, I had it happen once when there was 5+ fish halfway up the water column, but it straightened itself out. And if I was going to sit in the house, I’d turn it to manual dynamic to lock it in at tha depth and it worked flawlessly.
My only problem I’ve had is the carrying case is a little awkward. It works, but isn’t the best design. So I can either deal with it or grab a needle and thread and hand it to my girlfriend to fix it for me!
