The Theory Is Real
Surveillance-Pigeon Whistle

Surveillance-Pigeon Whistle

Three-tone brass whistle. Interrupts pigeon-type drones without alerting real birds.

$31.00

A brass whistle tuned to three specific frequencies that are demonstrated to destabilize the gyroscopic hover of pigeon-type surveillance units at a range of up to 6 meters. The same frequencies are outside the alarm range of biological pigeons, crows, and songbirds, so you can deploy in public without starting a flock panic.

The whistle is loud enough to be noticed by humans in the immediate area. We recommend carrying it with a printed card explaining it is for personal use; we have included one in the box.

Lanyard included. Do not blow directly at a child.
