I just got mine a week ago. Haven't had it on the ice yet and I have a battery/charger problem.. After 24 hours I never saw a green light and only showed 11.6V.... I ran it dry and then tried charging it to see if it would fix the problem.. Now the charger blinks red and the unit won't turn on. I emailed them about it and bought 2 extra batteries. We will see if that fixes the problem...I think it's a good unit overall and being able to upgrade it wil eventually cure the bugs
My LX-7 jumps around "with my jig" when I have it in dynamic mode but if I set it manually everything is fine. I am running the 3.1 software which was installed when I purchased in December.
Do the upgrade it will solve the jump and allows you to use the dynamic depth
