Technology
The DOG | CAT REPELLER PRO incorporates technological
innovations and is developed with components
manufactured under strict RADARCAN® specifications for
the greatest reliability and effectiveness.
INSonuerit 4.0
Our own advanced technology based on the use of specific
ultrasound frequencies studied to find a natural method of
protection against dogs and cats.
Ultrasound consists of high-frequency sound waves which
are perceived by dogs and cats, but inaudible to humans.
The ultrasound waves fan out the DOG | CAT REPELLER
PRO uni-directionally like fluorescent light. Hard substances
(walls,ceilings, furniture, glass, etc.) promote better spreading
outof the sound waves, as they bounce off these surfaces,
whereas soft materials (cardboard, curtains, carpeting, etc.)
absorb the sound waves.
