Gamma String Tension Tester

Calibration is trust. Without it, numbers are guesses. A tester shows what the bed is actually doing after the string sits.

Check the customer's racket before it leaves the shop. Check your own between sessions.

Measured Accuracy: Reads stringbed stiffness on the spot. No guesswork about how the tension settled.

Durability: Clean mechanical build. No batteries, no electronics to fail.

Fast Read: Press, read, done. Usable between warm-ups, practice, and match play.

Who It Is For: Coaches and stringers who want the proof in hand, not just on the ticket.

Gamma Quality: Built to the standard that has defined Gamma equipment for decades. Trusted by players who compete.

Tension is not a feeling. It is a number.
