Pretty much par for the course.. You really have to have a big spotter and a small depending on your hunt. EHD50 i borrow and I own a Swaro 65mm. As far as costs??? I really couldn't afford to not have one. I hunt with people who are always saying they can't afford one. I tell them to hold on a minute because I just spotted a buck that I have to go shoot And if they had this spotter then they wouldn't have to waste their money on all the additional trips it takes to get a deer/elk/bear/whatever.
