I use many Binocs but favorite at this time is a Kowa Genesis 44. My favorite spotter is a Pentax PF80 EDA w/ Pentax SMC 20 eyepiece. The available eyepieces for Pentax spotters is a big bonus for me. I have found some crazy stuff on Mt Rainier with this spotter.. Just a good bang for $ unit. I'm eventually going bite the bullet on a pair of Leica 10x42 Noctivid. That will be my last pair...
