Many a turkey has been
called in and harvested with out a decoy. So do you have a Call?
Even if you are hunting way back in some wilderness area you don't need a bone saw as meat can be deboned and packed out with just a really good knife. So do you have a knife?
A blind can be put together with what nature left in the area, brush, grass, trees. So you don't really need a blind to have a good hunt.
Sling for a rifle is real handy as you mostly walk from point A to the hunting spot, but with a shot gun We hunt from point A out and back to point A and a sling gets in the way.
Bipod? I have been hunting for over 50 years and never had a bipod. I hunt deer from a stand and don't want one. I hunt coyotes also and still don't want one. I much prefer a shooting stick I have made my self. I have them that are tall enough I can shoot standing, spread them out and shoot kneeling & sitting. I also have one made from golf club shafts I use when sitting and prone.
Buy arrows from a archery shop or ammo for the gun.
