I have noticed that most people who chose the pepper spray option have never, ever actually shot a can of pepper spary. Mostly, I think, because it is so expensive! I am now a firm believer that if you are going to rely on pepper spary as a bear atack deterant, you must purchase at least one can to sacrafice for training yourself how to use it!
How far will it spray? The can says 50 yards, but is that reality? How do you remove the safety? Does it spray a stream or a cloud? Does the can have enough propellent to launch the pepper into a brisk wind (most bears are surprised from down wind, you know)?
Something as simple as removing the saftey can be confusing and almost impossible durring a bear atack, if you have never done it before.
I am almost positive that most people who are hunting have taught themslves how to use a firearm, but not their bear spray!
