Can I get a bigger reflector? On a few occasions now I've gotten a false reading due to the fact that for whatever reason my laser has gotten slightly off track and is no longer hitting within the bounds of the (somewhat small) reflector target area. I'm not sure why this happens, because I have it mounted as tightly and securely as possible. I think it just gets slightly off over time, with the daily movement of the door, vibration, maybe even temperature changes, etc.
So I'd like that reflector area to be about twice as large. It would still serve the same purpose but with less false readings, correct? Is this something I can order? Or is that same reflective material (or something similar that would work) commonly available in stores? (Home Depot, Lowes, etc?)
