I have a rangefinder thats the size of a camcorder and am looking to upgrade. I am an avid bowhunter but also riflehunt at times. Do i need a rangefinder that has the (arc) technology or is a rangefinder a rangefinder? I don't want to spend the $300 on the Bushnell scout 1000 w/arc but want more distance than the nikon bow hunter offers.
