Guardian Golf Cart Alarms attach to the undercarriage of your cart to deter thieves with no need for complicated wiring. Mounted under the vehicle, the alarm monitors vibrations and when alerted produces an ear piercing alarm. Waterproof, shockproof, and the only alarm shielded from the elements, Guardian Golf Cart Alarms can take a beating from the everyday conditions you find beneath your cart. Every unit comes with directions on how and where to best install your alarm, as well as a 'Guardian Alarm' sticker to let thieves know it's not worth messing with your vehicle.
