Thanks guys for the answers. I wasn't tryiny to spoil the fun.
Gadgets are always interesting.
Just as I will be using a chain saw capstan winch to raise limbs as a cheap substitute for a ratcheting lowering device. Jim, you need an eight foot pole for the Big Shot, a six leaves you way down on your knees. A trigger isn't needed until greater accuracy for longer throws is required. Anyhow, an inexpensive, innovative, self fashioned spud gun sounds neat, and a lot cheaper than the elaborate real line guns that Wesspur used to have in their catalog. I wasn't tryiny to spoil the fun.
