I vote always/almost always. I find them invaluable for looking ahead before moving into an area, differentiating between brown bumps and animals, scouting, differentiating between sex of animals at distance, looking through brush, and generally enjoying the birds and other wildlife. I probably spend 1/3 - 2/3 of my time when hunting looking through glass. I almost never hit the woods without some and for how and were I hunt I sometimes consider them more important than my weapon of choice. I've taken home quite a few animals that I never would have known were there if I had left the binoculars at home. I've also filled some nice buck tags that I wouldn't have been able to ID as a legal buck without them because the brush was so thick. It allowed me to punch through the brush and count tines as they moved along then scan for shot windows to thread the needle through. My second best buck to date was taken solely because I was able to ID him as legal through the brush and pick a shot window out with binoculars and that wasn't even in very open territory or over a long shot distance; it just happened that the glass helped me to better ID and plan for a shot that would have been too risky for me to want to take without being able to plan it like I did and my naked eyes couldn't cut it by themselves.
