Like you guys mentioned, the 80s, 85s take up a bunch of room.
I always carry my 15X56 Swaro binos + tri-pod.
At one time I had a 80mm Skyline as well and carried 2 tri-pods to boot. Basically, including the glass around my neck, I carried 20lbs of optic related weight, plus my pack was almost full before the other gear went in.
I'm curious what type of tri-pod setup you guys use?
I have a Outdoorsman tri-pod with pistol grip for the 15X56s. It works great for them. I'm leaning towards just getting an adapter for the spotter although changing will take a minute or two. The extra weight/space of a second tri-pod isn't worth the speed of going between binos and the spotter, IMO.
Looking for other ideas.
