A device for practicing putting a golf ball, with an audible feedback signal that indicates that a golf ball has successfully hit the device. The device has a flat circular base with a printed circuit board attached, and a sensor or array of sensors contacting the entire outer rim of the base. An elastomeric membrane covers the device and the circular sensor, and transmits shock to the sensor when a golf ball impacts the device. The sensor or array of sensors produces a trigger signal upon impact of the ball, but is not activated by shaking, tipping, or pressure which might be associated with travel or handling. The audible feedback sound is stored in digital format.
