How would you get down if you were hanging from a normal harness just attached to the tree?

In that case you would have totry to get to your sticks or steps but if you are using a climber, your left with cutting the strap andclimbing down the tree! Depending on the size of the tree and your physical ability this will be difficult.

With the fall guy you can alsotry to get to your sticks (or what have you) but if in the case of a climber, you can grab the tree,disengage the locking mechanism and climb down STILL ATTACHED. (the locking mechanism will disengage with a little upward movement) this way if you slip again while descending youwon't fall the rest of the way.

I use the fall guy, it is a great system.

I have never used a harness of any type, its one of my resolutions next year to make sure i use one as much as i possibly can.

GREAT resolution!
