I am a golfer and recently purchased an Optic Range Finder for use in measuring distance. The unit that I purchased is the "Newcon Optik LRM 1500 SPD". This range finder not only measures distance in Yards and Meters; it also measures speed in MPH and KMH !!!
It's a very nice hand-held device for around $350.
In any case, I wondered if I could use it to set off my RADAR/LASER detector? IT CERTAINLY DID !!!
I found it useful for testing the range of my LASER detector, as well as useful for my original intended purpose of purchase (golf).
For More Info:
P.S. I do not work for these guys, nor am I attempting to promote their organization in any way, shape, or form. I did discover an overlap that might be useful for some of you guys with RADAR/LASER detectors out there.
