Let me expand my post a bit. For those of you who do take the tripod, what is your go to set up for binos? And, if I would change my mind and take a spotter the one below will be with me. Maybe even in lieu of binos. I got this as a gift last year but have not even tried it yet. If I drop the bino harness this spotter is no heavier than binos and harness.
It's important to remember that when using these optics, the vast majority of the time you're
studying what you see inside them, picking things apart while looking for tiny items like ears, antler tines, hooves, etc.
It's only a small percentage of the time where you'll see a buck right away, and most often right when you get a new view as you change position early in the morning, like coming around a hill. Having those chest binos allows you to cover a lot of area the quickest, trying to find animals that are up already. But after that, you're working hard in your glass, studying what you see. Looking into shadows, trying to find the small parts that are visible.
During full daylight, if you see a buck standing up it's generally because that buck is getting up to adjust his bed, to get out of the sun as it moves across the sky. So you might only get a minute or so to spot him before he beds back down. Which means you want maximum field-of-view while doing that kind of scanning and picking apart a hillside. That means binos. When on foot, I mostly only use a lightweight spotter to check what I see in the binos, or to spot-check a promising outcropping or shadow farther away.
If I could carry only one optic into the field besides a rifle scope, it would be 8x or 10x binos. Then I'd add a spotter. Then I'd add high-power tripod binos, like 15s or 18s. But in the field I spend the
vast majority of my time inside those high-power binos.
