Hunting I generally use my East German Zeiss Jenna. 7X40 A bit heavy but almost unbreakable. Quality glass with range finding
reticle.
Not good for birding or fast viewing changes, each side has focus/diopter
adjustment--I generally set them once I'm in my hunting spot and leave
'em.
Birding and general use my Optolyth. 8 X 40 Quality glass, light weight, harder to find in the USA these days--IF I could only have
one set from those I currently own, these would be it.
Travel when I still want some bino's Steiner's. 8 X24 Smallest I really like to go, could use for hunting-just have not, good quality
for price. Other uses as well, day trips in the canoe, birding, etc.
In the kitchen for backyard viewing--old Brunton's 7 X 42--first pair ever bought with earnings from first job outta college. Well
used
Tiny chinese cheapos in the middle, 8 X 21 I got in a gift box, live in the vehicle...actually used them on a backcountry trip when
I forgot a better set...I suppose better than nothing....
Buy the best glass you can afford---as you can see many people have more than one pair.
