THE SAFETY OVERRIDE
A whistle that cuts through wind, traffic, and distraction.
Frequency Sweep (4kHz - 12kHz): A rising tone is evolutionarily harder to ignore than a static tone. This sweep triggers the "Orientation Reflex" in the canine brainstem.
NEXUS INTEGRATION
Remote Activation: The "Nexus Collar" contains a cellular chip. If your dog escapes, you press this button in the app. The collar (miles away) emits this sound at 90dB, signaling the dog to stop or return.
