Seal Shield is a Acoustic Harassment Device (AHD).
The Seal Shield produces a powerful signal, utilising intensity and frequency to deter marine mammals by causing discomfort to the approaching animal.
Seal Shield aims to reduce seal depredation by producing random high frequency sonar pulses during the hauling phase of fishing.
These pulses are specified to emit within the hearing range of seals. The pulses are not harmful, but are highly annoying.
They do really not like it.

sound

Our sound signals are regularly updated, so the animals will not adapt to the new circumstances.
