Ultrasonic repellers omit ultrasonic frequencies
and or predatory sounds deterring animals from
settling within a designated area based on repeller distance length. Deck-Guard has been specifically designed to emit frequencies at 30kHz to 55kHz,
the level of frequency that deters birds of all sizes.
These frequencies (aside from predatory units) are completely undetectable by most humans, dogs, and even cats.
Ultrasonic repellers have been used by the military
since the early 70’s and have been proven to work effectively. Today, commercial grade repeller's are used on bridges, high rises and public buildings
in successfully repelling birds from destruction and noise in a humane friendly way. Deck-Guard uses the same technology, but designed for the needs
of the recreational marine industry.
Deck-Guard has been successfully tested on the following:
Albatrosses Anhinga Razorbill Shearwaters
Auklets Boobies Skimmer Skuas
Cormorants Dovekie Terns Tropicbirds
Frigatebird Fulmar Ducks Geese
