Using the tick marks works a lot better for me than using a pin for some reason. Doesn’t matter for shooting dots but for actually shooting deer it makes a big difference. I didn’t like how far apart the tick marks were at 20 so I erased them and made new ones farther down. I also added marks at 5 yard intervals. Then I drilled and tapped a hole in the top and installed a bow sight light off of Amazon. I basically use it as a multi pin sight except it has a clear field of view. The v part of it makes for a good reference if you have to guess the range and can tip you off if your on the wrong tick marks because it won’t look right.
