Vibra-phone 280 is for you. No tools needed. Just clip it on to your detector and plug it in to the headphone jack in place of your headphones.
Vibra-phone 280 vibrates to indicate your target. Vibra-Phone 280 uses a standard 9V battery. There are two adjustments. One sets the sensitivity or level when the unit will start vibrating. The other adjustment provides a shot pulse of vibration to a long pulse to match the tones normally provided by your detector. Set it once to match your detector. Vibra-Phone 280 works with all common detector models except for Minelab and Fisher detectors.
