A device powered by solar energy, making use of sound waves to repel harmful rodents(moles, voles, etc.)
By emitting sound waves, the Solar Mole Repeller drives away underground rodents very effectively. The sound waves will irritate them, simulate danger, and repel them away from the irradiated area. Transmitting sound waves every 40 seconds or so, the Solar Mole Repeller is effective within an area of 650 square meters.
The Solar Mole Repeller radiates in all directions. Avoid any obstruction and let the sound waves be emitted freely. To make the best use of the product, we strongly recommend an installation of 2 devices at every 30 meters for ground areas frequented by rodents.
The Solar Mole Repeller’s power is supplied by a solar cell, a rechargeable accumulator collecting power for operation at night. When the accumulator is fully charged, it can supply enough power for the dark hours, thus ensuring a continuous around-the-clock operation.

technical data:

Please note:
first,check the ground surface before using it.frozen soil ,irrigated or waterlogged ground is not suitable .Dig a hole into  solid earth place the device.The density of the soil will greatly affect the effectiveness of the device. The more solid the earth, the better the device will be functioning.
No hammer should be used in installation.
Installation:
1.Connect the cable with socket at head, tighten can not depart easily (refer to below photo).
2.Fix the bar and the top together.
3.Insert the bar into the earth, be careful not to use excessive force lest the device be damaged, or bump into any obstruction.

Technical update:
The device use computerized inching control technology, it is combine the signal output with DC charge function. So the socket (refer to above photo) is not only signal output socket, but also is DC charger. this new technology apply is more convenient to customers operate and bring the additional value to this models.

Warning:
1.The base of the top shall be exposed to the outside, according to the terrain varies ensure the water does not exceed the save line (note illustration).
2.Before first use,you’d better insolate the solar panel for two days,then connect the cable 2 and insert into the earth,so it will have a better effective.
