I have one of these with two sensors. It works like it is supposed to.

I'm not a fan. I own six sets IIRC.
Two 9 volt batteries. Always dead unless you tape the switch in the off position. Even if you case em in foam surround with a little slot for the switch, you got me how... somehow
One of the two batteries is not in a proper holder inside, just wedged between the side and a circuit board. A battery often bumps itself loose, mashing things around inside.
The screens are only glued on, not other fastener. If left in sunlight (on top of an amp rack outside) or near heat (in an amp rack drawer sitting on top of an amp chassis, lets say) the screen glue looses and drops the screen inside.
I also don't want to bad mouth them over something I can't remember exactly (its been four or five years) but I guess I will get it all out. Once when I called the service number about some other issue, I learned that the accuracy was not as close as I had assumed. Especially when you go through the effort to make a prediction shooting 300' with a Martin rig. I wish I could remember the tolerance but I was not impressed. Maybe someone here knows exactly.
Sorry for all the slander. I would be happy for you to have had a great experience with them and prove me wrong about all of it. I would give ours another chance.
