Ultrasonic dog and cat repeller 

Sititek Grom 250M


•    Two ultrasonic generators with operating range of up to 20 m. The level of sound pressure produced by them is 2 times higher than the sound pressure level of the GROM-250M’s predecessor and much higher than other repellers. The sound pressure level is enough to frighten even the most furious dog away.

•    Frightening effect is forced by stroboscopic flashes. 0.5W LED designed to produce flashes can be used as a mini torch when it’s switched to the permanent lighting mode.
•    Built-in buzzer is able to frighten not only dogs but hooligans as well. The device is equipped with a function to produce heavy sounds of the human hearing range. The buzzer can be used for raising a red flag when you are in the field or attacked by hooligans for example.     

 Unique anti-theft mode. The anti-theft mode is intended to protect your stuff and prevent theft while staying at airports or train stations or other places where your stuff can be stolen. The device is equipped with a specially designed signal cable you need to pass through the handle of a bag and connect to the repeller. As a result you will get a simple but reliable security system.

•    The device is absolutely harmless for animals. Dog repeller influences the hearing of animals only, frightening them by ultrasound. High frequency ultrasounds are out of human hearing range, and using the device causes no discomfort for human at all.
•    The device is ergonomic and easy-to-use. It’s powered by lithium battery and requires no special maintenance. It’s very easy to operate the device, all you have to do is to choose the mode you want to use and press the button. The repeller will do the rest.

SITITEK's GROM-250M Ultrasonic Dog Repeller provides effective protection from dogs 

It’s easy to operate the dog repeller, so it can be used by children and adults to protect themselves from stand-alone animals and packs of dogs. The key benefit of this model is that there are two ultrasonic radiators that produce the sound pressure of 125 dB each. The ultrasound’s frequency and volume have been chosen in such a way as to frighten the dogs of all breeds.

Ultrasonic Dog Repeller can be used for dogs training and uprooting bad habits of your pets as well. For example, you can discourage the cat from sharpening its claws on sofa influencing it by ultrasound of reduced power. You don’t harm the pet by doing so, but you will form the stable conditioned reflex not to sharpen its claws on your sofa.


GROM-250M Ultrasonic Dog Repeller’s design 

The device has an ergonomical enclosure in the shape of ribby box that’s designed in such a manner as to lie comfortably in your hand and not to slip out. Electronics are protected from damages by solid plastics. Even in the case of heavy stocking or falling from low heights, your repeller is protected securely.

There are holes for radiators at one of the end faces of the case. At that face end the ultrasonic radiators and LEDs are located and by that face end the repeller should be directed to the dogs.  The opposite face end is equipped with a special plastics loop for passing through the strap supplied that is intended to carry the repeller on a hand.

In the upper panel of the case the start button is located, and the function switch is in the side panel. To activate repeller just press and hold the start button. You can easily do it with one hand, but at the same time accidental pressing is impossible because the button is recessed into the case.


GROM-250M Ultrasonic Dog Repeller is easy-to-use  

The operating principle of the device is emitting ultrasound at 25 kHz that produces a sound pressure of 125 dB at 1 m distance.  It’s enough to frighten even a very furious dog away.

To frighten activate the frightening mode and next press and hold the big round button on the top panel. After the device faces the dog with emitter’s side and it starts emitting ultrasound coupled with bright LED flashes. You can change the repeller’s direction to maximize the effect; as a result a dog will start moving back and then run away.

As practice has shown, the more aggressive a dog is, the more effective it will be influenced by ultrasound. For GROM-250M Ultrasonic Dog Repeller the maximum range of frightening is record-breaking 20 m.


Mini torch may be useful outdoors and on a trip

GROM-250M can be used as a mini torch. To switch the torch on, you should set the function switch to the permanent lighting mode. After it 0.5W LED stops flashing as while frightening and starts to light permanently. Its brightness is enough to illuminate a dark road, stairs of a ladder or a keyhole.

GROM-250M Ultrasonic Dog Repeller is effective against hooligans

The device is fitted with a special security mode, in that by pressing the button "Fire" a noisy buzzer starts. It will be useful in critical situations, if you are attacked by hooligans for example, compelling them to retreat.


GROM-250M  Dog Repeller can be used as an Anti-theft Security system 

The device comes with a specially designed signal cable that is connected to the charging jack. To protect your bag you need to pass the signal cable through the handle of a bag and connect to the charging jack. If anybody tries to steal the bag the cable will jump out of the jack and the buzzer will be started by breaking the circuit. It will not stop as long as it will be switched off on the repeller.


SITITEK GROM-250M is powered by built-in 250 mA/h lithium battery you can charge from 220V mains. It makes it easier to operate the product and drastically reduces operation costs.

GROM-250M Ultrasonic Dog Repeller is completely safe to use!
