I have a pair of Swarovski's and a tri-pod adapter for them. Your eyes will thank you. Once you spend days looking through glass for Coues in AZ youll appreciate using both eyes.You like 10x42 power with premium glass?
I do have a spotter and some of my buddies have BIG spotters. They are nice, just allows you to pick things apart and get a more accurate judge on antler size and a few other things to help plan a stalk.
I do all my initial glassing with my binocs and if I have a spotter with me and/or time permits I will get out the big glass.
Of course, if your glassing miles away a spotter will work much better but in reality your probably not going to do that or your guide will have a spotter. I say upgrade your binoc glass (you can use it here) buy a tri-pod adapter and decent tri-pod.
