I currently have a Bushnell 1500 w/Arc range finder,and I am pretty happy with it.I am intrested in upgrading to a Swarovoski though.I would like to hear from some people that have them what kind of performance they are getting with them.With my bushnell,I can range a large tree from 800 yds.,I have ranged houses from 1200 -1300yds.I am guessing I could range a deer from 600 yds.The reason I am considering upgrading,is because I want to do some long range varmint hunting,I would like to be able to range groundhogs from 600-700 yds or more.Would that be realistic with a Swarovoski?
