New Digital RF Technology
It is the latest Digital RF technology. When the distance between Master and Slave is over 6~15m (Short distance) or 15~25m(Long distance), a high beep alarm is triggered on Maste(95dB) and Slave(95dB), thereby alerting you to check your valuables.

(As battery life decreases, the alarm volume decreases.)

Smart Detection
The working distance between Master & slave is 0~120m at line of sight.  The closer to Slave, the more LEDs light and the rapider melody beeps.  There is also a low battery alarm for low power detection.  (Terrain and other environmental factors can affect the range.)

The Slimmest!!
The thickness of Slave is the slimmest (2.8 mm only). The Slave can be  easily put into a wallet or a luggage tag.

Sleeping Mode
It can be switched to ¡°Sleeping Mode¡± when the alarm function is not needed.
