ERT 300 Tenniscomputer (Model #AERT)

New technology! This machine displays current string bed stiffness (dynamic tension). It also indicates the power and aggressiveness of play, and alerts when it is time to restring. It provides highly precise measurement through an electronic simulation of the ball impact. Pocket-sized, cordless, and easy-to-use. This works with any racquet and string type. It is microprocessor controlled and battery operated.

PLEASE NOTE: We can ship this machine to other countries. Please email us for more information or add this machine to the shopping cart to find out what the shipping cost will be to your country.
