For bowhunting I don't think you could beat the Bushnell Scout. It used to chew batteries but from everything I've been told or read, Bushnell fixed thjat problem. I have a scout and love it. Small, compact, ranges out to around 700 yards or so. It also has a scan mode for taking readings on moving targets. I remove the battery after each hunt to help preserve them a little longer. It's never been an issue with me.
