If You are a serious western Hunter, Quality 15s on a tripod and if You use a spotter it needs be quailty or nothing. I have tried spotters in the range of 1,000$ and under and none of them are worth a crap And I can't afford $3300 for the best thus I get by with quailty 15's only. I am talking Swaro ,Zeiss , Leica...... Minox and Vortex are worth for the lower end of top notch binos. I had a Vortex scope on a 300 win Mag and it did ok but got rid of it didn't like the feel. Some here will dissagree with me but down here in AZ,we do more glassing than any where with big binos . When I was in N.Dakota in oil feild I even used 15 hunting Turkey in the rolling hillsout west. Some Guys here will use High qualty 10's on a tripod too. If You are some what young find away to get the best and You will have it for many years..........BOB!
