## Questions & Answers

**Q: What diameter and lenght of pvc tube to use as a cannon?**
A: I used 1 1/4” by 6.1” long PVC pipe. That length is 10 wave lengths for 22 kHz. Works good for the dogs across the street. I also used a remote control switch to active it. Press the button for 10 or so seconds rather than leave on continually.

**Q: How many tweeters will the m161 generator handle?**
A: Max 2

**Q: Hello, can this be used in a car to a avoid running over dogs and cats on the streets?**
A: I would say NO based on my experience with it having NO effect at all on any of our neighbors dogs, wild deer, ground hogs, raccoons, squirrels, coyote etc.  Very disappointed…

I have heard good things about the Deer Whistles or Wildlife Warning Devices sold at any box store which are only like $5.00

**Q: Is the remote control switch mentioned by others available on Amazon?  Does this come with directions (I am a novice).**
A: Search amazon for remote outlet switch. They are pretty common and many use them to turn lamps or other devices on/off by remote. Just plug the 12 volt AC adapter into that. (The LE Power Adapter lets you hot wire with an adapter it comes with.)

## Customer Reviews

### ⭐ no effect on cats, dogs
*by R***L on June 3, 2023*

does not work on dogs, cats at all, they barely flinch. probably need to hook it up to a high power amp with high capacity tweeters, then should work.

### ⭐⭐⭐⭐⭐ Great stop barking trainer.
*by T***O on July 11, 2018*

This is my second bazooka. Works great. The neighborhood dogs are becoming well trained to stop barking - much quieter. Have it connected to a remote so it’s only on when the button is pressed. When a dog barks press the remote for 5 seconds or so. The dogs soon learn that barking is unacceptable.

### ⭐⭐⭐⭐ it works
*by B***B on October 31, 2019*

Works great...the mutt next door starts frantically yipping and trying to get inside its' house!
