Ultrasonic dog repeller: which is better

Ultrasonic repeller is a device that does not harm dogs, but at the same time reliably protects a person, maintaining a distance between him and the dog. To find out what their principle of action is, which of them are the best and what you need to pay attention to when choosing a model, you need to pay attention to the main characteristics and parameters.

Varieties

Now on sale are two types of ultrasonic repellers: stationary and portable.

Stationary They are large devices, the purpose of which is to ensure the absence of dogs in a rather large territory (yard, private possessions, territory near shops and offices, spaces of kindergartens or recreation centers, etc.)

They are designed to simultaneously protect everyone who is on the territory, therefore they have a very large capacity. When choosing such an apparatus, one must take into account the radius to which the ultrasonic waves propagate. For the operation of these devices, an electrical connection is required, but some models are powered by solar panels. The cost of fixed installations is usually very high, but cheaper Chinese models can also be found.

Portable or pocket repellers are characterized by very small dimensions and light weight, so they are convenient to carry with you in your purse, briefcase or pocket. They are universal, because everyone can use them, regardless of age. Power is supplied by batteries. It is this type of repellers that is most in demand, as it provides individual protection of a person anywhere.

Operating principle

The mechanism is based on the fact that the hearing of dogs has a greater range than human. If the human ear perceives a sound wavelength of up to 20 kHz, then in dogs this figure is twice as high - up to 40 kHz.

Ultrasonic scare devices differ in power, and this is the most important parameter. The higher it is, the louder and more unpleasant the sound for the animal. At low power, the dog simply may not respond, and the radius in which the sound waves propagate will be too small, that is, the attacking animal may come too close to the person.

Specialists warn that ultrasonic repellers with very high power can cause side effects in the person who uses them. They appear in a headache or pain in the ears.

Selection options

Ultrasonic repellers operate in a range inaccessible to the human ear, and their power is measured only by special sensitive devices. It is practically impossible to double-check whether the declared characteristics correspond to the actual ones, therefore unscrupulous manufacturers may not adhere to them. For this reason, it is very important to buy similar products from trusted companies about which you can find real reviews.

Another important parameter is the effective range. It indicates at what distance the dog will experience the most discomfort from the emitted ultrasonic waves. In most cases, it ranges from 5-15 m.
