i got a yardage pro a few years ago and it paid for itself 1st time out. at the time i was using really heavy carbons and at 25yrds i dropped about6" from there to 30yrds. i ranged my shooting lanes and one was thirty at the end of it and sure enough the doe i got was right there i just put my pin up in the top of the ribs and made a perfect heart shot. the one i got is plenty for bow hunting and i think its still around 130-140$ at dix sporting goods. just take it to your stand and range out your lanes and landmarks and you never have to pick it up when a deer is there. i love it and wish more people get one just to save that one miss or wounded deer is totally worth it.
