Swing Speed Radar Sensor with Tempo Timer - Like New

Measures clubhead swing speed and tempo time to help golfers optimize their swing to increase distance and improve swing consistency. Work on tempo for full swing - 3:1 and tempo for short game - 2:1. Can hit real balls, a whiffle ball, Birdie Ball, sponge ball or equivalent to simulate a real ball, but must swing at a ball replica to release the club properly. Just swinging does not record. Immediate feedback provides you a basis for determining swing improvements. Range of speed measurement from 40 MPH to over 200 MPH. Actual swing Tempo Time, from the start of the club takeaway to ball impact is measured to one hundredth of a second. Use it at home in the backyard, indoors or outdoors in a hitting cage, at the driving range. Storage bag, new batteries, and manual are included. No wear and tear evident--like new.
