Take Control of Predator Attacks

INTELLIGENT

ACOUSTIC DETERRENT

This is an intelligent acoustic deterrent system designed to deter seals and sea lions from fisheries. It’s proven effective worldwide, with more than 600 systems deployed since 2014 to protect sites in Scotland, Chile, Finland and Russia.

SealFence uses a unique soundwave delivered through a network of projectors placed around each site. These work together to create an acoustic fence of protection that often completely eliminates seal and sea lion attacks.

Many of OTAQ’s innovative technologies are incorporated into Sealfence, including Active Condition Monitoring (ACM). This constantly monitors and records performance, with full control available via a touchscreen located on a barge or boat.

Despite integrating incredibly advanced technology, Sealfence is also tough and has been designed to cope with permanent installation on even the most exposed fisheries. You can trust in SealFence: it’s proven reliable with a negligible breakdown record backed up by industry-leading levels of support from OTAQ.
