There are many home and personal alarms available, but none have a deterrent that can prevent or discourage an encounter quite like ultrasound. The effect does not cause injury but produces a debilitating highly discomforting feeling of nausea, disorientation and paranoia. These ultrasound pain field guns and generators can be tuned to target certain animals and unwanted human intruders. They Are Readily Available to The Public and Do Not Require Special Licensing or Other Red Tape! Our Ultrasound Pain Field Guns and Sonic Shock Wave Generators Can Discourage and Intimidate Intruders, Drive Out Animal Pests, And Train Dogs to Stop Barking. These products are not to be confused with some of the higher-powered devices costing thousands of dollars such as L-rad and other government units used in dangerous uncontrollable riots, piracy and large-scale operations and only available to law enforcement
Ultrasound Pain Field Guns and Sonic Shock Wave Generators HT90P - Assembled and ready-to-use Ultrasonic Receiver with Headsets, Dish, & Microphone Mount. See our Surveillance category for listening devices that will amplify "normal" sounds that the human ear can normally perceive. * This device is not made to hear normal audible sounds.
Narrow band tuning dial from 23 to 27 kHz (-3db points).3.5 mm phono jack for audio output into headsets or recorder or both.Pinpoint Those Annoying Sounds Coming From Bark Controllers, Animal Repellers, and Those Who Might be Purposely Using Ultrasounds Against You for Harassment The 12" aluminum parabolic dish increases the amount and sensitivity of collected sound (increases the reception of fainter sounds, or those from a longer distance), and provides more of a directional target location. Hear The Astounding and Incredible World Of High Frequency Sounds - Beyond Frequencies Detectable By The Human Ear!īattery operated directional device detects sounds beyond the range of human hearing, with narrow band tuning from about 23 to 27 kHz (-3db points), allowing you to hear and pinpoint mechanical, electrical and biological sounds such as leaking gases, air, water corona leakage motor frictional sounds potentially including bearing wear breakdown noises bats, insects, and other sounds of mother nature a hunter's aid for high frequency sounds made by animals traveling through dry woods or even wet grass - even beading water! There are countless applications for this unit. This unit opens a whole new world allowing you to listen to sounds you didn't think even existed! Its directional reception allows for the detection and general location of ultrasound that may be used as harassment. A crumpling plastic bag, moving coins, a key chain, rain drops, etc. It can serve as a detection device allowing one to hear animals or people walking in the woods on dry ground, or even on a wet day. Leaking air, water, gas, steam, pipes, and machinery wear are only a few of the many faults easily made detectable, potentially preventing more serious events from occurring. It has many uses, both in the scientific field especially entomology to study insects, bats, other animals and fauna. Listen to the amazing world of high-frequency sounds. This unique item is a directional ultrasonic heterodyning type listening device. Included headsets may differ from those shown in picture. Determine what and where it is coming from!Ĭlick HERE for actual bat sounds recorded using the HT90 The ultrasonic generators are devices that create ultrasonic sound waves, which can be used in some novel ways such as a safety deterrent or conditioning device.Īdvanced Electronic Circuitry lets you hear only Ultrasounds and Reject Normal Sounds. The ultrasonic receiver is a device that can detect sound waves that are normally beyond the range of human hearing, and then translate this signal to audible frequencies. This page describes some very unique items generally categorized as "ultrasound"
