I wouldnt dream of not using one. Sitting in your stand and taking yardage measurements to various open areas near your stand will do a few things.

1. Lower the chances that you will use the wrong pin based on yardage -or eliminate it.

2. Keep your scent to a minimum in the stand area because you do not have to step off yardage

3. Give you a confidence boost because thinking about yardage is one thing you will not have to do when a Whitetail comes along....
