SeaGuard 2-Channel Seal Deterrent

The Gael Force Marine Technology SeaGuard Seal Deterrent is a proven industry ‘must have’. Using the renowned Airmar DB+ II projector which has been modified and redesigned with approval, performance and lower power consumption.


The SeaGuard does not use sound alone to deter (and keep deterred) seals. It uses physiological techniques rather than psychological scaring. This is used to create an acoustic barrier or fence around each cage and the site.

The improved performance of the DB+II projector comes from our modification and redesign on the control system, now 50% more efficient in power consumption.

Approved and tested by Airmar themselves, the SeaGuard system works perfectly with existing projectors so sites can, if required, upgrade to the new control box.

The flexibility of the new Control System combined with the existing projectors moves the Seal Deterrent to a new level. Not only will it protect sites but it also assists ADD’s to become more cetacean friendly. Having the ability to start at a low level will ensure wildlife know it is there and prevent the “shock” of a detector based system firing when the wildlife is close.

  • Multiple programmable and random firing patterns.
  • Cetacean friendly.
  • Improved Airmar DB+II Projector.

 Power Supply

28v DC, 48v DC and 90v – 240v AC versions available.

 Power Consumption

50% more efficient than the DB11.

 Multiple Settings

The SeaGuard System offers multiple and random firing patterns.

 Multiple Pulses

As well as varying the firing pattern, the SeaGuard Deterrent can vary the length and breaks of the firing pulses further preventing the seal from learning when to attack.

 Fault Indicators

Extremely bright colour changing LED fault indicators for each channel. A single LED for each channel will display for power, soft start, projector firing and projector failures. The operator will see quite clearly that all projectors are firing or of any potential faults.

 Soft Start

The SeaGuard Unit has a soft start system to protect wildlife when the system is switched on and off.
