A crossbow offers many advantages for survival situations. While Discovery demonstrates how to make one by hand, it’s still basically the same weapon and benefits. The crossbow would be a better option than a longbow especially in a scenario where you may have lost your rifle or just didn’t bring one along.
DIY Survival: Make a Crossbow from Scratch
This weapon does not demand too much physical exertion like a longbow does. All you have to do is to draw the string and you’re ready to shoot. Shooting positions can be varied and your height will not be a hindrance. Another advantage is that you do not need to master the draw-aim-shoot technique. The crossbow is fairly easy to use so it’s a good idea to learn how to use it.
