Cueball speed measurement device

My first post in years!!
I was wondering: I was at Valley Forge this year and saw at the Predator booth a device that consisted of two little blocks containing lasers. Each block went on either side of the table, so that it created two beams about 10 inches apart going across the table. The idea is that there is a timing device that can measure the time taken for the cueball to break each beam, and since you know the distance between them it can calculate the speed of the cueball. It is a much more accurate system than a radar gun (I think?). Anyway, I was wondering if anyone knows where a rig like this could be purchased (or built?). Thanks for any info.

I think that a similar system was in the Pool & Billiard booth at the BCA Trade Show about ten years ago, and the designer was selling the thing. Maybe he still has one. P&B should know how to contact him.

I've built similar devices, and have a pretty good idea of their cost. The problem is I have no idea how much a device like this might be worth ... so I'll just ask ... what do you think this should sell for ? The device would likely have the ability to measure speeds from say 10mph to 30mph with a resolution of say 0.1mph ... how are those spec's ?

I'd maybe bump the spec up to 10-40 mph, just for those rare individuals who can hit 30+.
I picture a setup like this costing a couple of hundred dollars. I have little to base this on. I suppose I should say that I would be willing to pay a couple of hundred dollars.

It is doable for a couple hundred dollars. PM me if you want to pursue this.

I saw that set up. I have been thinking about that. Does that devide automatically adjust the position of which the breaker breaks from, or is the difference considered insignificant?

The actual distance travelled by the cue ball between the two dots is almost always longer than the actual distance between the dots. Also, will the readings be interferred by the cue tip moving right behind the cue ball?

I know that a radar gun will produce error such as the angle of elevation, but if I can place it at table level, I wonder which method is more accurate?

I've been kinda curious about radar guns over the last few weeks and I've been doing some searching around the net. As far as radar guns go, I'd have to put my money here...

I haven't found anything related to laser beams on speed sensors, but obviously they exist. I'm kinda new to the technology involved here, so take my suggestions FWIW. :)
 
i used some measurement equipment in a physics lab and calculated my cue ball speed for a cost of 10 minutes. Calculations had to be performed manually. And the carpet was extremely nappy. Knowing the cueball speed didnt help my game much though.
