Spot hogg - Tommy Hogg: Find highest point sight housing can be set (peep has to be in right position first). Then find correct position of sight housing for horizontal adjustments (want to be close to the middle, so you don't run out of adjustment when sighting in and have to start over). Set middle pin(s) in center of sight housing. Position other pins using an old sight or measurements from between pins on an old sight (gets you closer faster). Shoot and fine tune pin location. Once sighted in, put a piece of tape on wheel, mark home position. I shoot every distance with my top pin, until I run out of clearance moving down. I use my pin gaps to help estimate how far to move the sight down, since my pins are sighted in. Once I have marks for every 10 yards, find a sight tape that matches. You can shoot two distances (20 and 60 plus) like mentioned before, but i like comparing every 10 yards. Then pick which pin you want to be your slider. Currently I use my 40 on a 3 pin. Align tape so you are close to the 40 yard mark. Then go shoot and adjust sight if needed. Then move indicator so it lines up perfectly with 40, if needed. If you want to change with pin you float, put sight in home position and move tape to mark corresponding to whatever pin you want to us.
