Abstract
An alarm system is provided for alerting a golfer about a forgotten club. A divot tool incorporates a radio transmitter powered by a rechargeable power source for transmitting a coded transmission. A radio receiver tuned to receive the coded transmission includes logic circuitry that generates an alarm signal whenever power associated with the coded transmission drops below a threshold level. One or more alarm devices are coupled to the logic circuitry to generate alarm(s) when the alarm signal is supplied thereto. A power source is coupled to the radio receiver for supplying power thereto and for supplying a charging current for the rechargeable power source via an electrical coupling. When a golfer places a club or other accessory on the ground, the divot tool is placed near the club. As long as the golfer remains within a prescribed range, no alarm will be activated. However, if the golfer moves further from the divot tool than the prescribed range, an alarm is produced. Alerted to his forgetfulness before leaving the vicinity, the golfer then simply retrieves the club and divot tool.
