Spin, speed and
contact point.

A 6.2 g sensor that clamps into the throat of your racket and samples the frame 1 000 times a second. It logs every shot you hit — rpm, head speed, and where on the string bed you made contact — and exports the lot as CSV, FIT or JSON.

It clamps into the throat

The triangular gap between the two arms of the frame, below the string bed. Sit it in, turn the collar a quarter turn, and the jaws pull against the inside of the frame. Nothing is glued and nothing threads through the strings.

The TRACQUET ONE tracker clamped in the throat of a tennis racket, below the string bed

Most trackers read your wrist. This one reads the frame.

A wrist sensor infers the shot from how your arm moved. TRACQUET is clamped to the frame, so it measures the collision directly: spin in rpm, head speed in mph, and contact point in millimetres from centre.

Seven parts: a spring, a shaft and a 9-axis sensor in a sealed aluminium barrel.

TRACQUET ONE laid out as its seven components

Chrome-silicon wire at a variable pitch, 26 rising to 34 N/mm. It suspends the sensor and, because its rate is known, turns contact into a number.

Records offline. Syncs on the dock.

Sessions are written to onboard storage, so nothing needs to be paired courtside. Set the tracker on the magnetic dock and it charges while it uploads — about forty minutes to full.
