Install this audio device on your boat and watch how winged pests vanish.Designed to scare birds away from a large boat (or up to one acre of land), the Bird Chase Super Sonic is an outdoor sound device that broadcasts a variety of distress and predator calls that send chills down a bird's spine. The unit can be programmed to target specific species, such as seagulls, pigeons, crows and many others, or set to "general" to scare multiple species of birds. Distress and predator calls of birds are broadcasted every ten minutes. When birds hear these calls, their natural instinct is to leave. Bird Chase Super Sonic is weatherproof and has a day and night setting. Designed to operate off 110V Ac, it includes a 15' power cord.
