Abstract: What has been disclosed is a golf bag alarm system which actuates an alarm when a thief attempts to remove the golf bag without authorization. In a weight sensitive embodiment of the invention, even the attempt to remove a golf club from the bag will cause the alarm to be sounded. A second embodiment of the invention, sensitive to movement of the bag, will actuate an alarm when the bag is moved from its nominal resting position. The alarm system is portable and may be housed within the golf bag itself or within an associated golf cart. The battery which powers the golf cart may be utilized as the power source for the alarm system carried by the golf cart.
