Pocket Radar is a small quality tool.

Used the Ball Coach Pocket Radar at practice tonight with academy students and found it a productive tool!

One has to stand back a little to capture the ball properly and from a good angle in order to achieve better accuracy. I use a long tripod/selfie stick with attachment for a phone to measure the serve. For Forehand or Backhand readings one can use a regular tripod with phone mount (these come with all selfie sticks....and you can use the other part of the selfie stick for this: https://www.facebook.com/545400872300223/photos/rpp.545400872300223/553332614840382/?type=3

This is a great tech. tool that can be used very productively in teaching tennis. Also see a previous post on this page for additional info. Feel free to contact me for more information.
