I Own the Lx 6, got it for x-mas. It worked perfect for about 8 outings with v3.17, then one day my jig started fading in an out only time you could see it was when you moved it. That night I went home frustrated and found the new upgrade v4.07 was available. I downloaded and it helped with my fading jig, but developed all types of different problems which everyone else has mentioned plus this. I now have target displayed on the dial all the time, which I discovered is ducer offset. It goes away when I do a factory reset , but comes back. I also contacted Marcum and sent them pictures and I was told to try the the same things. open water mode. ducer high in the center of hole.They also emailed me the old v3.17 version. I’m surprised I found all these complaints, when Marcum told me they had over 2000 downloads for V4.07 and not many complaints. I’m addicted to the unit now. but don’t Know if the problem is with my unit or the firmware? They should run these new versions for awhile and work out the bugs before releasing them. I guess were the test team without benefits. When I spoke with them on the Phone You can Tell there frustration from all the call volume. I still think I have a problem because my headache started with v3.17. Still not giving up on Marcum its a great unit when working properly lets go Marcum Makes us Happy!

I have an LX7 and I’ve been fishing a shallow water Bluegill factory all winter that is 4.5 – 5.5′ of water. The way I set my unit up is I run the transducer just barely in the water. I run it in the 10′ mode,8 degree cone angle,& open water setting. Sens at 3 & Target at 1. I can see my jig up to the 3′ mark and we have about 13-14″ of ice a little less in some areas but nothing less than 10″. I run the flasher dial and Zoom bar on the right. You would think with the 8 degree cone angle the gills would never have much separation when near your bait with only a 7″ foot print but the zoom bar definitely proves otherwise. Hope this helps.

Thanks Glen, I own an LX 6 and having the same problem, but mine worked great for about 8 uses in ice fishing mode, then suddenly my jig which was a bros bloodworm started disapering, that night I researched and found the new firmware upgrade V4.07 I uploaded and tried it out in 9 fow and the problem got worse. I called Marcum and they told me to try the open water setting like you mentioned here, they also sent me the old V3.17 Firmware for if I like to switch back. I Just Don’t understand why it worked perfect for 8 trips out and then I’m pulling my Hair out. Is there a problem with my unit or is everyone experiencing similar problems with there LX 6 ,7 or 9 units.
