Testing out my Thunder 100 Retriever launcher that I just purchased, and showing one of the many ways that I will be using it to train my young Labrador Retriever for hunt tests. In this video, I am able to practice steadiness at the line, as I take my time moving around and shooting bumpers, while also being able to fire diversion shots and get my dog used to the sound of shotguns without having to load or unload anything. You can find this Thunder 100 launcher at www.sitmeanssit.com Off-leash dog training accomplished using the ‘Sit Means Sit Collar’. The Thunder 100 doubles as a shotgun simulator and bumper thrower. No need for poppers or primers. It is 100% safer than current shotgun blanks. One can of fuel is equivalent to 0 in poppers. Can be used equally well with right or left handed throwers. No moving parts! Will shoot in the rain and requires no oiling or cleaning. Built in redundant safeties guarantee safety and reliability. Dogs know the difference between primers and shotgun sounds. Use a product that gets them really excited and can be heard for hundreds of yards!
