WHAT IS THE ​ERT 300 COMPUTER?

The ERT300 tennis computer is a microprocessor-controlled measuring device that determines the string and playing characteristics of your tennis racket precisely and quickly. It makes the technology of world-class players accessible to every dedicated tennis player, stringer and coach - all in a small compact format. It is the only microprocessor worldwide for automatic measurement of string bed stiffness, as well as playing characteristics of any tennis racket.

WHAT IS THE DT OPTIMAL VALUE

Every player has his individual optimal DT value.
Playing strengths are roughly divided into 4 DT ranges, these can also overlap
-LO: DT 28 - 34 Defensive play, mostly from the baseline
-MID: DT 35 - 41 Dymamic offensive play
-HI: DT 42 - 46 Powerful, aggressive play
-HI+: DT 47 - 54 Very fast, aggressive play.

what does dynamic tension dt value mean?

The DT value defines the playing characteristics power and control.
A soft-strung racket with a low DT value generates more power through ball acceleration.
A hard-strung racket with a higher DT value offers more control.
Every player has their own optimal DT value.

what influences the dt value?

The DT value is influenced by the following factors:
-Stringing weight ( reference tension set on the machine ).
-Accuracy and condition of the stringing machine
-Technique of the stringer
-Material and diameter of the string
-Head size and stringing pattern of the racket
