These are going fast.   They are die cut reflective dots at a fraction of what you can buy from the manufacturer.  Best material.  Die Cut with tabs.   Strips of 123 are going for an introductory price of $15, but here, you get two strips for $25  Also have sheets of 1000 if you are interested in another auction.  Just search Quad dots.   These work fine on Quad or HMT or GC3 or Hawk  for motion capture to look at angle of attack with hi-speed cam.

NOTE AND WARNING:  BEWARE OF. THE COPYCAT SELLERS ON EBAY.  You will see that they try to copy everything I've done and undercut price.  You can find me in Facebook as the founder and moderator of the largest group on the web focusing on technical aspects of launch monitors.   I personally test the materials utilizing multiple launch monitors running concurrently.  MANY have reported that the copycat products ARE UNRELIABLE.   Order those at your own risk.   When they don't work, come back here.   Thanks for listening.
