Ultrasonic Dog, Cat, and Animal Repeller in Keychain Form – an innovative compact device for humane and effective protection against unwanted contact with animals. Perfect for use in urban environments, outdoors, during walks, runs, cycling trips, and travels.
The principle of operation is based on generating a powerful ultrasonic signal with a frequency of 30,000 – 40,000 Hz. This sound range is well-perceived by animals (dogs, cats, rodents, and others), causing them strong discomfort and a desire to move away from the sound source, but it is absolutely inaudible and safe for humans. To activate the repeller, simply press the button — a directed ultrasonic impulse is immediately emitted from the miniature high-frequency speaker.
Effectiveness and Range:
- Maximum effectiveness is achieved at a distance of up to 1 meter.
- Working range — up to 2 meters, allowing you to stop approaching animals at a safe distance.
- Due to the signal directionality, you can target a specific animal without affecting others.
Main Applications of the Ultrasonic Keychain Repeller:
- Protection from aggressive or stray dogs – an essential accessory for pedestrians, runners, cyclists, postal workers, and couriers. Helps quickly and safely stop an animal without causing harm.
- Child protection – thanks to its ease of use (one button) and compact size, even older children can use the device to ensure their own safety during walks.
- Protection of pets – the repeller can be used to drive away aggressive animals from your dog during walks without causing discomfort to your own pet (when aimed correctly).
- Behavioral correction of pets – helps gently train your own cats or dogs to stop unwanted habits: for example, trying to jump on the table, chewing furniture, meowing or barking loudly at night, waking up too early.
- Repelling cats and other animals from private property, gardens, vegetable patches, garbage bins, cars, without causing them physical harm.
