Sonic Bird Repeller

Product Information

The Sentinel is a commercial grade, very powerful ultrasonic bird and Pigeon repeller / deterrent with an adjustable frequency for fine tuning to match the hearing of your target pest. It's extremely effective with a huge 50 Mtr(150 ft) range. The ultrasonic bird repellerproduces a pulsating and aggressive ultrasonic sound, similar to a siren but silent to humans, whicha bird perceives as extremely unpleasant and therefore avoids the area being protected by the Sentineldeterrent. This way, you can chase away birds and not be worried about your bank balance. Warranty and Maintenance As many recent repellers are motion-activated, the birds do not even need to be very close before the sound goes off. Applicable Bird Species This repeller is battery powered and comes with a 50 feet extension for plugging. This is unlike the Yard Gard above, which is not rechargeable. Pros

It works on 4C batteries, which can last for about one month of continuous operation. The batteries are not rechargeable, so they would need to be replaced regularly, depending on usage. It has a power cord so it can easily be plugged in if mounted close to an electricity supply.

The main reason why the Sentinel ultrasonic repeller stands head and shoulders above other models is because the frequency is adjustable. The user can very easily adjust the sound to get the optimum effect for the animal you are targeting . The Cleanrth Bird Repeller is a powerful motion-activated bird repeller. What makes it stand out is that it detects body heat rather than movement. Another impressive feature of this device is its motion sensor. Once any bird is within 10 meters of the machine, it detects movement and emits threatening sounds to scare them off. As many ultrasonic devices are installed outdoors, it may not be close to an electricity source. The best bet for outdoor use would be to go for those with solar rechargeable batteries. Budget

This is why electronic deterrents are regarded as more effective bird deterrents. But if you're willing to learn the ropes; which is an "oh-so-easy thing" to learn anyway, you'll never go wrong getting the best bird repellent of choice. Depending on the area you’re trying to protect, the device’s coverage and capacity should be considered. Many ultrasonic devices work best in semi-enclosed or enclosed locations where the sound waves can bounce off the walls and ceilings.

Pigeons specifically detect infrared sound (below human hearing range) and not high-pitched sound. Therefore, choosing the right device would help to scare birds off effectively. Safety Unlikethe lower priced battery operatedmodels, this powerfulultrasonicrepeller requires a 240v mains power supply. And because it is mains powered, the Sentinel is always working, giving protection 24/7. There are several reasons to consider safety. First, you want to ensure the bird repeller doesn’t kill the birds you want to scare off.Like most good things, this product has its flaws. While it is weatherproof, the device is not very stable in a moist environment. Pros It has flexible functions for its LED strobe light, sound frequency. The frequency set would also determine who would hear the sound - If set to sonic, it would be heard by birds and humans, but at ultrasonic, it would be heard only by the birds. Conversely, the hearing range of most birds is between 1,000 – 4,000 Hz. Some species of birds, such as songbirds, can hear up to 20,000 Hz, while birds like pigeons can detect infrasonic sounds (0.5 – 10 Hz), which is below the human range. It emits ultrasound waves of 15,000 – 25,000 Hz and periodic chirp sound to keep birds away. The sound pressure of 90 decibels (dB) is beyond the human range of hearing, so it cannot be detected, but it annoys birds and scares them off.
