on number one and sight your front sight elevation by either lower or raising it with a slotted screw driver to the distance of 20 yards. Once number one is sighted in for 20 yards, it is a matter of praticing with your options of number 2 and 3 on your back sight to see what distance they will be sighted in for. A good way to get a good idea what distance each number is giving you, would be by shooting over a body of water near land, first you measure off the land in yards, then by shooting in the water by the land you can see where your pellet hits the water and what distance each number is giving you. Then later on you can use paper target to really sight then in with slight adjustments to the back sight.
Now, lets say your B-42 is a .22 cal. and is shooting around 640 fps, being that number one on your back sight is sighted in for 20 yards or 60 to 80 ft., number two should give you shots sighted in the 30 to 35 yards range or around 90 to 105 ft., maybe even more, which means number 3 will be sighted in for 40 to 50 yards or more. Only praticing with this sight will let you really know what your air gun is capable of doing.
This does take some pratice, but once you get know the sight, it is fun to use.
