in the category of "total useless" how about a bow sight

you have 800 archers shooting at 300 guys with swords and pikes.

of the bow that this sight is mounted upon...... I shoot a 50 pound bow (all I can draw reliably now at 74) and I would never dream of taking a shot over 40 yards away on a deer. Maybe even not then if he is headed my way or only a really good broadside shot with no wind. At 500 yards your arrow will move 20 or more YARDS with a 4 to 5 mph cross wind. I tried once to see how far I could shoot. Set up was at 45 degrees with only a slight gust of wind. My arrow went about 180 yards and 15 to 20 yards to the left of my aim point. That was when I was still shooting a 60 pound bow. 500 yard for a bow means you are going to have to pull around 130 to 150 pound bow at a minimum. Burris would be better served to save its money and build more of the 1X4X20 or 30 mm handgun/375H&H Magnum type of scopes. JMHO

weight added to the bow. Someone else if making sites like this( I forgot who) and they are even more $$$$$$. I can't justify $800. I think their market research is about to be proven wrong about customer acceptance.
