Ultrasound Bird Scare. Scarers of rodents, mice, moles

To protect the garden in the country, people acquire special devices for scaring away birds. Many models are also suitable for rodents. The devices differ in power, operating frequency and type of power source. Some scarers operate only on the 220 V network.

Parameter of the minimum frequency at them reaches 30 kHz. Power averages around 4 watts. The devices operate on the principle of ultrasonic radiation. For this purpose, the models have a compact resonator.

Devices for birds

Models for birds are usually made with a stand. The case is protected and is not afraid of bad weather. Power is provided by lithium batteries. Also it should be noted that in the market there are models with several speakers. Resonators are most often used for unipersetting type.
