Hunting Kodiak brown bear with archery equipment can get exciting in a hurry. Not only does this necessitate getting extremely close to a very large (and potentially dangerous) animal prior to taking the shot, but the initial shot very rarely instantly kills the bear.
Shot placement is always important when hunting, but it is even more vital in this case. Unfortunately, the hunter in this video did not place his shots well and things got very interesting as a result.
As you saw, he missed the bear completely with his first shot, then wounded it with his second. Luckily, the guide bailed him out by making a good shot with his rifle at the last second and everyone walked away from the encounter unharmed.
This is a good reminder to always carry a good bear defense gun when in bear country.
