Check those batteries.
Just a reminder to not overlook batteries in gear as the season nears. Yesterday I was moving some targets around to practice from my treestand. When I went to check yardages with my rangefinder I found out my battery was dead. I'm glad I found out now and not when in a stand needing to be sure of yardage on a shot. Don't overlook your rangefinder battery when you change out flashlights etc.
