- We compare two dog training / deterrent devices, both labeled as AD-100. One has a very different sound than the other. (I use a "bat detector" to convert the ultrasonic waves into the human audible spectrum).
A bit of background music, made with MS Songsmith and then played on the Roland BK-3.
Hope you enjoy the video, and please subscribe to this channel. Thank you!
