I agree, anything with a 25 mm objective is going to be hard on the eye's long time viewing and will not be so great in low light
due to I am lazy, and try to carry as little as I can when bow hunting, I personally got a nice used pair of 10x42 and made monocular's out of them by cutting in half, I get good enough field of view, and takes up a LOT less space on me, but use this for not so wide open places
other wise I carry a 10x42 bino when hunting out west in wider open terrian
brand of bino's
there is a reason some get more $$, its the edge to edge clarity and light transmission that makes they worth the $$$, IF and ONLY IF< you spend HRS behind them, they will save you tons of headaches from glassing for long periods of time
for most folks middle of the road glass is fine, just try if possible to get to look at things 70-100 yards away and look at distortion from edge of view to edge of view, on CHEAP glass you will really see the difference here, even on scopes and what not's
I sold optic's for a long time, and trust me, from one SAME exact model bino to another you can see a difference, its like pick of the litter at times
on higher end things, you get more consistent on quality, but low to middle end??
look before you buy!
