Blackfire Anti Dog Ultrasonic Max Dog Repeller

A device that generates ultrasonic waves at a frequency that is deterring to dogs, but inaudible to humans. It also has a training mode, emitting gentler ultrasound waves to aid training, and an integrated LED torch built into the casing. Powered by a built-in battery.

Thanks to the use of durable and lightweight plastic, the device is lightweight. Its small size and included lanyard make it easy to carry.

The device includes 3 sound emitters operated by four buttons placed at the top of the casing, easy to use. On the left side, there is a switch that allows selecting a constant frequency, variable frequency, or lock. The constant frequency is 25 KHz, and the variable frequency ranges from 25 to 30 KHz.

• The first button activates high-frequency ultrasound and the torch in strobe mode. The maximum runtime is 80 minutes for constant frequency and 90 minutes for variable frequency.
• The second button is responsible for emitting ultrasonic waves inaudible to humans. The maximum runtime is 90 minutes for constant frequency and 102 minutes for variable frequency.
• The third button operates frequencies audible to humans. The maximum runtime is 15 h.
• The fourth button allows choosing torch modes. The maximum runtime is 7 h.

The device has an LED. The appropriately marked button at the top changes the light modes: pressing once activates continuous mode, and pressing twice activates strobe mode.

The emitted ultrasonic waves are harmless to humans and animals. The sounds in deterrent mode are perceived by animals from a distance of up to 7 metres. Although humans can hear them, it is not as loud as for animals.

The device is powered by a built-in battery with a capacity of 1600 mAh, charged via a USB-C port. Below the buttons is an LED indicating the battery charge status; green light means readiness for operation, and red indicates low battery.

Survival and outdoor: ideal during hikes in wild areas, on camping trips, or during long treks, effectively protecting against encountering stray dogs. Ultrasound does not disturb the natural environment, being inaudible to humans.

Camping: the device provides protection around the tent, trailer, or camper, guarding against unknown or aggressive dogs. Its compact size means it does not take up much space.

Sport and physical activity: practical during running, cycling, or Nordic walking when threatened by an aggressive dog. Its small size allows for easy carrying in a pocket, waist bag, or on a belt, always within reach.
