If you hate having to wring the necks of crippled waterfowl, check out The Finisher, which was designed to quickly and humanely dispatch wounded birds.
Unfortunately, dealing with crippled birds is something that just about every waterfowl hunter has to deal with. Nobody likes to see animals suffer unnecessarily, which is why the founder of Adrenal Line designed The Finisher as a tool for quickly, cleanly, and humanely dispatching injured birds.
Check out the video to see how The Finisher works.
Beware: this video contains graphic footage of a hunter dispatching crippled ducks, so don't watch it if you're squeamish.
If there is a better tool out there for accomplishing that unpleasant task than The Finisher, I haven't found it yet. This might be something worth getting for any waterfowl hunters on your gift list this year.
