2 x Solar powered card ejector - Ultrasonic device

2 x solar-powered card ejector - sonic alarm

Sonic alarm for chasing away cards and field rodents, powered by solar batteries.
For continuous operation even at night, the dog remover includes a rechargeable battery that charges during the day. Aluminum tube with high resistance and excellent sound propagation properties.
Efficient system for generating disturbing sounds.
The device against cards is simple to use, does not require maintenance, just bury the Anti-Card device in the center of the affected surface.
How it works:

The device vibrates, like a mobile phone that alerts you when you receive a call. These vibrations propagate through the earth, being felt by the animals we want to combat up to a distance of approximately 625 square meters.

The vibrations are emitted at regular time intervals, to simulate ground movements, which are perceived and interpreted by the pests as a potential danger and they will leave the area covered by the device. In addition to vibrations, the device also emits through a speaker and sounds, to increase the efficiency of the device.

This model is powered by a photovoltaic panel directly from the Sun. Therefore, it does not require periodic checking and changing of the batteries, increasing the comfort in operation and maintenance. The built-in accumulators will store the energy accumulated during the day, to power the device during the night as well.

Installation:

The device has the shape of a mushroom, and is composed of two parts. The lower part has the shape of a tarus, it is made of aluminum, it is inserted into the ground and contains the mechanism that emits the vibrations and sounds. The upper part, made of green plastic material, contains the photovoltaic panel and the power supply system, and will remain above the ground, exposed to the light of the Sun.

Connect the two parts, upper and lower (see photo), then insert the device into the ground about 3/4, so that water does not enter inside the device.

Attention: The covered surface can be affected by the nature of the soil, as well as by objects or relief. A loose or boggy soil will not propagate vibrations as well as a well-compacted and dry one. Also, tree roots, foundations, stones in the ground can affect the propagation of waves. Keep these observations in mind when you install the devices.

Applicability:

It can be used in gardens, agricultural lands and other outdoor areas where rodents live.

Advantages:

It does not produce smoke, does not use toxic substances, does not affect domestic, pet or farm animals, such as dogs, cats, birds, pigs, chickens, etc. Also, it doesn't kill pests, it just drives them away, thus eliminating their decomposition in your gardens.

The vibrations emitted are not perceived by humans, so the device can also be used at night, without the risk of disturbing the neighbors.
