'You apparently are not familiar with the appearance and silliness of the blind mentioned in the OP. It is not a conventional sit inside blind. See the images before you get back up on the soapbox.
No, I'm familiar with the product in question AND the local contingent of "purist priests" on this site that label anyone who hunts turkeys from a ground blind as "non-ethical hunters". Enter the search terms "turkey" and "blind" if you don't believe me. The obvious point I was attempting to make was that many of these same purists who scoff at the idea of using the new Primos blind/decoy/umbrella, or a regular ground blind for that matter, have no issue at all trudging into the woods with a shotgun/ammunition combination capable of reliably killing turkeys out to nearly 100 yards. Personally, I don't have a problem with any of it, and take the position that if it's legal, it's OK. Now, I surely agree with comments questioning the safe use of hunting with the new Primos blind. It's certainly a non-starter on public land, and you better be damn sure no one else is hunting the back 40 you're walking into. That said, pronghorn hunters have been using a similar approach when bow hunting for over a decade. And they continue to do so, because it works.
