My PACT Club TImer III lasted about 6 years and stopped working today at the range. Sensor no longer picks up any shots, but par time function still works.
PACT offers a repair service for $20, or I was thinking about trying out a new brand. Opinions? I generally liked the PACT timer for its simplicity as I could clip it to my pants pocket and run both shot timer mode and par time mode easily with a single hand.
