I was ground squirrel hunting [ "sage rats" to hunters, "squeakers" to farmers and ranchers].

I compared:

Tasco 8x21 Essentials Binocular $10
Steiner 8.5x26 Wildlife Pro Binocular  $300
Nikon 9x25 Travelite V Binocular  $80
Nikon 12x56 Monarch ATB Binocular  $450

This is three pairs of small, fit in the pocket binocs, vs one huge pair carry around the neck binoculars.

The small ones had more field of view than the big ones [surprise to me].


What I learned was that the big binocs I just got from SWFA, the Monarchs, were no help at noon to spot a brown ground squirrel on green alfalfa.

They were good at seeing things at dusk that were too dark for the naked eye, but ground squirrels are down in their holes then.

Over dirt clods, the Monarchs could pick out the slightly golden shade of color of a squirrels fur vs the flat brown of a dirt clod. 
With the Travelites, the non moving squirrels were invisible among the dirt clods.

Once I spotted the invisible squirrel in the binoculars, the cheap Simmons 22 mag scope on a 10/22 could not pick them up.

What does it all mean?
1) Big binocs have less field of view.
2) Big binocs see in the dark.
3) Color corrected binocs can find camouflaged animals, but are still invisible in non color corrected rifle scopes.

1) You need a better riflescope.

2) Things like clarity and resolution are more important than magification and field of view.

1.

 

Big binocs does not have less field of view. high magnified binocs does have less field of view.

And there is differances betwen different makers in FOV.

Clark -

1) As previously stated, the higher power that you go, the more restricted is your field of view.

2) A crude measure of how well your binos will perform in the dark is referred to as the exit pupil.  This takes the size of the objective lens divided by the magnification.  As a result, the Monarchs, at 4.75 would perform better in low light conditions than the rest, which are all 3.0 or less.
