Scarecrow – Comorant Deterrent
Don’t let your prawn farm profits fly away! Every day a single hungry Cormorant will eat 30-40 or more prawn. Left unchecked a flock of hungry Cormorant can quickly result in substantial farm loses. Solar panel powered and using a daylight photo eye to activate a digital sound recording the Scarecrow – Cormorant Deterrent is designed to automatically broadcast the sounds of predatory orca through underwater speaker(s) to stop birds diving the prawn or shrimp pond for food.
Each Scarecrow –Cormorant Deterrent will operate 1 or 2 underwater speakers with the required 12 volt DC power supplied from either a 50 or 100-watt solar panel. The IP65 rated outdoor enclosure is prewired with a voltage regulator that incorporates automatic low voltage shutoff to ensure best battery charge and maximum battery operating life. Additional attention to detail includes enclosure mounted cable strain relief fittings for sealed power and speaker wire entry, clearly marked screw terminals for wire connections, as well as full inline fuse protection of all system components. Operator adjustments include a volume control knob managing sound output levels for the chosen 1 or 2 underwater speakers as well as full adjustment to the daylight photo eye used to set automatic daylight start and dusk stop times.
