It is a laser RPM reader. You stick a piece of reflective tape to the platter and point the laser at it and you will get an accurate reading. It cost something like $15 shipped. I've since just leave the tape on the platter, so I can check the speed from time to time. FrankC

It's very important that the strobe is battery operated and thus is not affected by drift of the frequency of your house AC. Furthermore, the KB disc is large in diameter relative to most, which makes for superior accuracy. Cost is $100, more than the cheapest and less than many. You have to go up to the Sutherland Timeline for superior accuracy, at ~$400. Cell phone apps are unreliable, according to scuttlebutt.
