Meridian Zero Humm Line

Scare birds off moored boats
● Stretch tightly between two supports and even a gentle breeze will cause Humm Line to vibrate, giving off a sound that birds cannot tolerate and stopping them from fouling decks and cockpits.
● Secure the tape to the forestay about 1 metre above the deck and stretch tightly to the shrouds and backstay.
● 30m of 5mm line
● No harm is caused to the birds.
