A Longhunter Challenge!

I challenge anyone to find primary documentation that a longhunter existed in the 18th century. By this I mean the word or term longhunter or long hunter actually being used in the 18th century. So far I have found no proof that this term was ever in existance before the 20th century!
So what was this so called longhunter supposed to be? I mean we now see adverts for "longhunter shirts" and "longhunter packs", and the list goes on as if this longhunter was something special, out of the ordinary compared to a woodsman. Well in fact the modern meaning of a so called longhunter is that he hunted for a long time, or he was in the woods hunting for a long time. Woodsmen who hunted commercially for meat and deer skins are now called longhunters because they were in the woods hunting for a long time, i.e. months at a time.
But this does not make them any different from any other woodsman who hunts, they did not wear different clothes or use different guns. My point here is, that if the term longhunter was not in use in the 18th century, then why are we using it now? Fine to say a woodsman has been gone for a long time, fine to say he has been out there hunting for a long time now, but to call him a longhunter? At what point is an ordinary hunter supposed to become a long one?
Personally I think it is time we stopped using this term "longhunter" until someone can come up with proof that the term was in use in the 18th century. Until then they are woodsmen and hunters regardless of the length of time they are in the woods.
