Portable Electronic Deer Alert: Advanced Audible Warning Device

USB-Powered | Magnetic Mount | 8 ft. Cable with ON/OFF Switch

Protect yourself, your passengers, and your vehicle from the unpredictable danger of wildlife collisions. Unlike traditional wind-activated whistles that are prone to clogging and only work at high speeds, ourPortable Electronic Deer Alert provides a consistent, high-frequency audible warning at any speed—even when idling.

With over 1.5 million deer-vehicle accidents occurring annually, the average repair bill now exceeds $4,000. This portable, easy-to-install device is your most effective line of defense against costly damage and dangerous road encounters.

Why Choose the Electronic Deer Alert?

Active Protection at Any Speed: Works perfectly in slow-moving traffic or at highway speeds.
Weather & Debris Resistant: Designed to stay clear of the dirt, grime, and ice that often render passive whistles useless.
Massive Warning Range: Emits an alternating audible tone that alerts animals from up to 2,000 feet away.
Zero-Permanent Install: The powerful magnetic mount allows you to move the device between vehicles in seconds. Perfect for rental cars, trucks, or family SUVs.

Key Features

Audible Dual-Tone Technology: Emits a specialized alternating sound frequency designed to catch the attention of deer, moose, and other wildlife.
Total Control: Features an integrated ON/OFF switch, allowing you to silence the device when it’s not needed.
Universal USB Power: Simply plug into any standard USB port for instant power.
Durable 8 ft. Cable: Designed to be thin enough to pass through door seals without causing damage or losing suction.
Portable & Compact: Small enough to store in a glove box when not in use.

How It Works: The "Train Whistle" Effect

The Deer Alert doesn't "scare" animals into a panic; instead, it provides an advanced warning. Much like a train whistle alerts a pedestrian, this device makes animals aware that a large object is approaching.

As your vehicle nears, the sound naturally grows louder, prompting the animal to pause and look toward the source. This eliminates the "startle response," making them much less likely to bolt into the road at the last second.

Simple 3-Step Installation

Place: Secure the magnetic base to your vehicle's hood or roof with the speaker facing forward.
Route: Run the durable power cable through the door opening and into the cabin.
Plug: Insert the USB connector into your vehicle’s power port. Flip the switch to "ON" and you’re ready for the road!

Note: This device is water-resistant. Please remove it before entering an automated car wash or if the vehicle will be parked in heavy rain for extended periods

How does it work?
The sound the Electronic Deer Whistle makes does not “scare” the Deer or other animals out of the road but rather makes them aware that something is approaching. The comparison is very similar to a train’s whistle. People are not instinctively afraid of trains or a train’s whistles but the whistle acts as an advanced warning that a train (possible danger) is approaching. People take notice and start watching for the approaching trains as the whistle grows louder. Deer can hear these warning tones from great distances. As the vehicle approaches the sound from the Alert grows louder and the Deer will take notice of the approaching vehicle well before it would have heard the vehicle, reducing the chance that the Deer will be startled by the vehicle and less likely to jump or run in front of the passing vehicle.

Slow down! Deer crossing. It's a warning to be heeded this time of year. Deer are on the move during late fall and early winter, either because it's hunting season or because they are seeking a mate.

Deer kill more people and are responsible for more property damage than any other animal.

Every year there are more than 1.5 million reports of automobile collisions with deer. This staggering number accounts for more than a billion dollars in insurance claims annually. With the correct technology of deer whistle deer avoidance systems, used with driver awareness, will reduce your risk of hazardous animal/vehicle collision by more than 70%.

On the highways and byways across North America, nearly 750,000 collisions occur each year between deer and vehicles. Efforts to reduce that number have spun off a multi-million-dollar industry: deer whistles.

PRODUCT COMPARISON

Peter Scheifele, director of bioacoustics research at the National Undersea Research Center, conducted a scientific study of deer whistles. Photo by Shannon McAvoy Scheifele, an animal bioacoustics and audiology expert, wanted to know more about the devices, so he and hisresearch team scientifically tested their effectiveness.

The small plastic whistles, easily attached to car bumpers, hit the marketplace several years ago. Some are sold for as little as five dollars. They vary in design, but their claims are relatively the same.Their manufacturers promote them as "acoustic attention-getters", alleging deer would react to the whistle by remaining still. "There has been a lot of conjecture about whether the whistles work or don't work, and we are one of the first independent groups to scientifically test them," says Scheifele, director of bioacoustic research at the National Undersea Research Center at Avery Point and a researcher in the Department of Animal Science.

He and his team tested six air-fed whistles in the laboratory and in the field. The study's goal was to determine the actual frequencies generated by the whistles and the intensity at which they are produced, compare that data to the hearing abilities of deer, and then take the animal's acoustic behavior into consideration. Following the directions on each package, the team mounted the devices onto a car's front bumper. Using a road closed to the public, they drove the car at speeds ranging from 30 to 45 miles per hour while recording sound and data.

"We tested them strictly from an acoustical point of view," explains Scheifele. He found that the whistles typically produce a signal either at a frequency of 3 kilohertz (kHz) or 12 kHz. Both, as it turns out, are problematic. The hearing range of white-tailed deer, the most common species in the United States, is between 2 kHz and 6 kHz, so the animal is not capable of hearing the 12 kHz signal.

Although deer may be able to hear the 3 kHz signal, it is only 3 decibels louder than the road noise created by the car, so the signal is buried. Scheifele points out that the situation would be worse with additional traffic in the area or if the wind was blowing. "All in all, the air-fed whistles do not make sense to me acoustically, " states Scheifele.

Since completing the study, a new electronic whistle has been put on the market. Although Scheifele has not had an opportunity to test it, he has examined its advertising claims. He says the specs for the electronic whistle are considerably different from those of the air-fed devices, so "there is a possibility that the electronic whistle is more effective than the air-fed devices." He has written a paper on his findings and submitted it to the Acoustical Society of America's Acoustics Research Letters Online where it will shortly be under review. So what is different about the Electronic Deer Whistle Deer Alert unit?

The electronic Deer Whistle is engineered to produce both a sonic frequency (heard by humans and larger animals like deer and elk) and ultrasonic frequency (beyond the range of human hearing but heard by smaller animals) to alert animals of your vehicles presence.

The Electronic Deer Whistle has an effective range of 1,500 feet and is proven effective to work at any speed.

The revolutionary new design incorporated in the Electronic Deer Whistle, Deer Alert unit ensures a tremendously effective device, which works with or without and maintenance to keep vehicle and it occupants safe from many of today’s road hazards.
