Based on technology developed by the USGA, the Field
Scout TruFirm Turf Firmness Meter is used to measure the
firmness of sports playing surfaces, especially golf greens,
fairways and bunkers. The device consists of an impact
plunger and a rotary position sensor. Once motion of the
plunger is detected the electronics will collect and process
the signal and send a measurement to an LCD display.
The measurement may also be streamed to a handheld
device via a wireless communications protocol using a
Bluetooth accessory (items 6490S, 6491S).
