I am looking at a product called the Air Launch King. http://www.rpsite.com/airlaunchking/
This is from the web site.
"Air Launch King is the manufacturer of the only automatic bird launcher/winger to throw multiple ducks, pigeons, 2" & 3" bumpers, and dead fowl bumpers.
Air Pro 13 bird launcher and the Air Rotary 16 bird launcher, makes bird hunting and retriever dog training easy.
Designed and patented by an Engineer who loves Bird hunting and Retriever training. "
Does any use or own one? What is your opinion of it?
