Hey guys,
I bought a used Marcum Lx-5 several years ago. It came with 2 batteries. Been working great with no issues. Then the other night I took it out and after 45 min it started acting weird. It was working fine when I got there, but then I switched holes and all of a sudden there was a lot of interference and the screen looked like there were weeds. But no weeds. And there was no red showing the bottom. I knew how deep it was and it was showing no red there. It was hard to see my jig and over time it would seem to fade out with less and less color even if I turned the gain up. Eventually all color faded to just a small yellow line where my jig was. Then even that disappeared. I tried playing with the gain and moved it back to the hole it was working on when I first got there but that didn't help.
I know the battery was fully charged when I went out there. But when I got home I started thinking the last couple times I charged it, it took a LONG time to get it back to full charge.
I always just assumed when the battery died, it would just shut off. But now I am thinking the battery issue might be causing what I was seeing the other night.
What do you guys think? Could this have been a battery issue causing the unit to act weird?
