Powerful Ultrasonic Dog Bark Deterrent - Stop Dogs Barking +Pest/Animal Repeller

Description

Ultrasonic Dog Bark Deterrent / Ultrasonic Generator
Now with 1/4"-20 camera mount for tripod.
This is a a Powerful Dog Bark Deterrent that can also be used as Variable frequency  Ultrasonic Generator for experimenting with Ultrasound.
(Most bark deterrents use the same 16mm ultrasonic transducer as handheld ultrasonic deterrents which have a range of only a few yards. And when we checked one with a decibel meter, it showed 77db, which is FAR less than the claimed 120db. And that's about 20db LESS than our bark deterrent.)
Some Testimonials:
"Hi Jaro,  I can't thank you enough.
I ordered the: 1 Powerful Ultrasonic Dog Bark Deterrent - Stop Dogs Barking +Pest/Animal Repeller
So far I think it's working, don't hear the neighbor's dog barking at everyone all day and night long and I live in an apartment complex and it's a small apartment. I turn it on while the dog is barking and after like 5-10 mins. he just stops and after that doesn't bark for most of day until few hours after I have turned it off." ...Mimi
"Just an FYI from the minute we turned it on the neighbors dogs stopped barking!
Thanks!!!" ...

"Extremely pleased with my first unit. Not only has lasted fine through snow and ice, but the adjustable frequency and loudness has been very useful for multiple dogs. Unfortunately I have two dogs angled 90º apart, one old and one young. With two units, I will be able to enable both at different frequencies with a simple homekit switch straight from my phone."  ...

"The thing works. Thanks!"
It can also be used for loitering control, when set just outside of audible range. In that case teenagers still can hear the high-pitched noise (while adults can't) and it'll drive them away. To repel dogs and encourage them to stop barking, set it also to inaudible range.
Comes assembled in plastic box, with AC wall adapter. For portable use, requires an external 12V DC battery.
Others sell dog bark deterrents that output a single frequency, which animals can adapt to, and after a while ignore. The advantage of this generator is that if that happens, you can slightly change the frequency which will overcome the adaptation.
And unlike other versions of dog repellents that have paper diaphragms, ours is WATERPROOF, so it can be used outdoors 24/7 for repelling dogs and wild animals. We dunked it, and it worked while under water for half an hour without a problem.
***************************
In the default Dog Bark Deterrent mode, frequency is variable between about 7kHz and 21kHz.
Use as an Animal Repeller:
Also Works to REPEL stray CATS and DOGS, RACCOONS, DEER, and BATS. Not so good for squirrels and birds.
Use to discourage Loitering:
Here is a report from one user regarding loitering:
"These teenager loiterers were oblivious to everything else we and the neighbors have tried - disapproving stares, Neighborhood watch signs, video surveilance signs(and cameras!), increased special police patrols - nothing worked until I bought this. It works like a charm! As soon as I see them gathering, I turn it on. Thug 1: "Hey what is that ~!@#$%^ sound" thug 2: "What sound?" thug 3: "You don't hear that &^%$? It's giving me a headache! lets go somewhere else"."
Customer Testimonial:
Here is a report from one user:
I wanted to tell you that with your ultrasonic Dog Bark deterrent I was able to train the neighbor's dog not to snarl and  throw himself against the fence at me. He rarely barks at us now. I can enjoy my back yard much more now.
Best regards,

Product Comparison:
We've recently purchased and tested one of our competitor's products.
Most bark deterrents claim about 4000 sq. feet coverage, which is about 65 feet effective range. The unit we've tested is claimed to have a range of 300' and 120db power due to their "high pressure" transducer, and sells for around . We've found that it has the same 16mm ultrasonic transducer as handheld ultrasonic deterrents which have a range of only a few yards. And when we checked it with a decibel meter, it showed 77db, which is FAR less than the claimed 120db. And that's about 20db LESS than our bark deterrent. And since sound drops in volume by about 6db per doubling of distance, our deterrent should have
at least THREE times longer range
than their 77db one.
