Grad Ultra 3D is the most powerful rodent repeller in GRAD product family. It is equally effective in both large and small areas. Due to 4 ultrasound transducers with the newest operation algorithm and a unique system of light exposure it scares away all rodents (mice, rats, hamsters, etc.) in the shortest possible time. It can operate silently and can be used in living areas.

Operates effectively even in extremely large rooms The device is a great solution for protecting both largest areas and small ones. Its high power will scare pests away even faster, if used in small areas. In addition, the power of the ultrasonic signal can be adjusted, if it is excessive or interferes with people nearby. The repeller is recommended for use in bakeries, kitchens, in cafes / restaurants, industrial premises / warehouses, country houses, storerooms, sheds, cellars, etc. |

Powerful ultrasonic signal with an innovative pattern A unique pattern of ultrasound generated by 4 transducers is modulated with low frequency. As a result, efficiency of the repeller increases, because the frequency of ultrasonic waves coincides with the frequency of some vital biorhythms of rodents and causes them to feel anxiety, fright and fear. Transducers work in pairs at different frequencies that leads to an increase in the power of the repelling signal and the possibility of obtaining a more complex vibration pattern. |

Equipped with blue-violet LEDs. Light flashes operate according to a specially developed algorithm, causing severe irritation of the optic nerves of rodents, general weakness, distribution of sleep and preventing their reproduction. |
