The new Pieps Micro beacon is the first of its kind to feature motion-sensing technology that automatically switches from send to search. This beacon also features the all-new haptic feedback functionality that vibrates when it picks up a signal. The Pieps Mico is also the smallest three-antenna beacon available to-date. It's perfect for side country and light backcountry where weight and bulk are a concern. Keeping your beacon's firmware up to date has never been easier than now. With built-in Bluetooth technology, you can wirelessly send the latest updates from your Bluetooth enabled mobile device. The Micro's advanced features allow you to focus more on the search and less on the device.
