Since when does “need” have anything to do with it. If they make it, people will buy it.
Oh, I’m quite sure of that. It will join the wide array of crap sold to hunters that a) they don’t need, and b) doesn’t make them better hunters, much less c) makes them better shots.
For the amount of money someone would spend on this widget, they could gain much more by buying ammo and just practicing their shooting.
I’ve always been confounded at the hunters who claim that they need (among other things): a rifle that will group 0.5 MOA (or less), the latest cammo, GPS systems, 6.5 to 20X optics (or, back east, optics at all - with exceptions for those who have eyesight issues that make iron sights hard for them), muzzle brakes (been down this road myself, and they’re worse than useless), bipods, ATV’s that cost $7000, blah, blah, blah.
