Lab Radar Problem

Has anybody that has a Lab Radar had any problems with it. I have had mine for a little over a year and have probably used it 4 or 5 times. Of course the warranty has run out. Last week I had it out and it worked fine for 10 series of 10 shots. On the 11th series, it picked up 8 out of the 10 shots, on the 12th series, it picked up 8 out of 15 shots, on the 13th series, it picked up 7 out of 15 shots, then it would not pick up any at all. These were 9mm and 45. From the getgo it never has picked up any shots from a 22 when I have tried to use it.
    I had it out again yesterday and it worked fine for the first 5 series and then I started getting irregular readings. According to it, I had one 9mm shot that read out at 3450 fps. I think I would have noticed that. I also had reading that would display nothing at the muzzle, but I would get readings at different ranges down range. I would get mixed readings of anywhere from 450 to 1100fps from the same ammo. Raises hell with the stats!
   I use a USB power source. I have also noticed that there is a thump from inside if I give it a gentle shake.  I also have noticed that the transmit power never goes above two bars. This is with fresh batteries or a fully charged USB power source. Am I doing something wrong?

Is it coming out of alignment on the target as you shoot?  My next guess is interference of some kind.  Either wave bonce back or electrical.  New security system in the area?  High tension wires?  Buzzing transformer?

I'd call LabRadar they are great to work with.  I was in conversations with them before their product came to market and bought one before they were actually in production - no problems with mine.

Hi Dave.....You are actually the person that I hoped would respond. Alignment Is rock solid with the target and there are none of the things that you mentioned in the area at all. Does yours have a thump when you gently shake it. Mine sounds like something is loose inside....Paul

No noise rock solid, doesn't sound good for your system .

If it were mine I'd open it up to see if I could pop whatever is loose back in place BUT I have done a ton of work on electronics over the years.  Best bet is to give LabRadar a call.  Please post whatever the fix is.

I'd almost bet a heat sink may have come loose.  I say that because it doesn't start to fail until you have been running it a while.

Thanks Dave......I'll give them a call Monday and see what they have to say. I imagine that I should call the Wichita, KS number.....Paul
