Developed in a marina, this gull scarer was designed as a seagull deterrent for use on boats to give protection without causing any problems of excess noise.
These units produce a high level of high frequency sound which has been proven to be an effective deterrent against birds.
In addition, they use a mimimal amount (4/5 short soundings per hour) of audible gull distress cries which is designed to blend in with the environment so as not to cause a nuisance noise effect, together they create a high level of protection against seagulls.
The bird scarer emits ultrasonic sound constantly to offer protection around the clock, whilst the audible sounds are automatically stopped at dusk and restarted at dawn, however, this can be overridden to work 24/7 if so required.
The device is designed with low power consumption in mind and will work for weeks on a 70 Ah battery should mains not be available.
Placement with good line of sight of the problem area is essential for best results with ultrasonic sound as it cannot penetrate any objects in its path.
Marine gull scarers can be supplied with a mains psu and a battery lead for situations where a mains supply is not available.
If using a battery to power the bird scarer, then use a 12V car or leisure type, either will work but leisure batteries are more suited to this kind of use, and whilst any size of battery will work, consider using a 70ah or greater capacity, this is particularly important if using a solar charger.
