Which would you guys recommend IOR 10x/40 binocs or Windriver 8x/40's? I'm really interested in trying the IOR's but I'm also not sure if 10x is going to be too much magnification for extensive glassing in Western Montana/Idaho. Any other recommendations for a pair of quality binoc's under $500? I'm just too hard on gear to pay much more than that. Right now I'm using a pair of military surplus Fujicon 7x/ 50's. Good glass but way too heavy. Finally, how do I learn how to use a military range finding recticle? Thanks guys, love the site.
