Just thought I should remind everyone even though they probably already know to check and change your rangefinder batteries often. Mine, in conjunction with my lack of self confidence cost me a doe this weekend. I was in my ground blind accompanied by my 6yr old daughter, and a well placed decoy, when out comes a doe. I look at my daughter and say &quot;There she is hunny at 30 yards&quot; &quot;Shes looking right at the decoy and doesn't even know we're here&quot;. and she replies &quot;Shoot her daddy shoot her. She is as close as your play deer&quot; so I draw and now its time for daddy to show what he's made of.<img src=icon_smile_cool.gif border=0 align=middle> Thunk shhhhhhhhh clack, clack, Thud. What??? <img src=icon_smile_angry.gif border=0 align=middle> She was at 30 yards. The range finder said so. How could this be??? After waiting for the doe to bound well out of ear shot. We go out to find the arrow, and see what happened. I had ranged a particular tree as I always do I will range a rock or a clump of grass. Something to give me reference when the moment of truth comes there will be no doubt about distance. When I ranged this tree I thought in the back of my mind &quot;Gee that looks a lot closer than 30 yards, but the range finder knows best its a lot smarter than me.&quot; <img src=icon_smile_blackeye.gif border=0 align=middle> Wrong your equipment is only good if it has been checked, and maintained thouroughly. You see the battery indicator showed half to three quarters full, but when I tested it it was really dead. When stepped off the shot was 22 yards. Moral (To save wasted opportunities, lost arrows, and a world of questions like &quot;What happened daddy?&quot Check your equipment.
