I seen a set of something like that at Cabela's or Gander Mountain, I forget. But they could be extended from like 22 inch all the way up to 60 inches or something like that. And the top had a saddle like design for use as a walking stick, but it really I think was to cradle the rifle. BUT I think they were two sticks and they had a one stick variety also, that you'd just extend and use. I think a tri pod would be a better shooting platform. I saw them on a show where they were hunting in Africa. They had one person who's job it was to carry the tri pod for the shooter. That site you posted.. they look really nice.
