Bear encounters can be very dangerous for hunters. Every year a few elk hunters become victims of bear attacks, so it pays for hunters to be on their guard and take every precaution to prevent a close encounter.
Some encounters can not be avoided. For example, this Swedish man is standing on a road. He is wearing orange like he is hunting but he seems to be only armed with a pistol or possibly bear spray (It is hard to tell in the video).
Whatever he is holding it really does not matter because he does not use it. He just gets big and yells and that startles the bear enough to make him runoff.
If that happened to me I would probably need a fresh pair of underwear.
