How to Use
Fasten the bracket to any sturdy loop, strap, or luggage handle. Grip the exterior tab firmly and pull straight out to arm the system. Move freely; the unit enters standby mode after a brief thirty-five-second calibration. Resume automatic tracking once the countdown finishes. Silence the alarm by pressing the tab back into its resting position until it locks flat.

You walk through crowded terminals or dim sidewalks knowing backup is attached directly to your belongings.

Engineered for solo college students, independent seniors, school-age children, freelance professionals, and night-shift employees who rely on fast visual and auditory warnings.
5 Frequently Asked Questions
Does the alarm work outdoors? Yes, the sealed interior tracks genuine human movement reliably while walking dogs, waiting at transit hubs, or setting up temporary outdoor stations.
Can I lower the volume? No, the internal amplifier maintains one continuous maximum-output channel to guarantee immediate crowd dispersal.
How often must I replace the power source? The ultra-low drain circuit maximizes standby longevity, though replacement frequency scales with daily activation habits.
