Any coaches using radar to gun pitchers at tryouts or perhaps to measure bat speed?

Personally I think the early use of radar is likely to cause injuries. Only mention it because I've heard nutty reports last year of several coaches bringing a gun to even the first day of tryouts. Also conveys the utterly wrong idea that speed is important in selecting 9th grade pitchers.

Same thing could be said, I guess, about stop watches to time 60s the first day or two.

I've never seen that at a HS tryout. I can't even think of why that would be necessary?
