you should put up a price range that you expect to spend for what you want.
you should also decide if you are going to use a thermal unit to detect animals
and for the use of lasers, what kind of distance, and terrain features you will be using them in.
for a sample experience of looking thru a monocular, vs binocular setup, take a toilet paper tube (in my example, the diameter was about 1 3/4 inches. cut it into 2" long tubes.
close you non dominate eye, hold one tube up to your dominant eye and look thru it, and try walking around, and doing things.
for a sample binocular, take the two tubes, and tape them to a piece of cardboard, spaced so each eye looks through the center of the tube, and walk around, etc, again with this setup.
this approximates the field of view of a monocular, so you can sort of get what you would be looking through if you don't have access to nv monoculars or binoculars.
finally, you could always see if you could rent what you think you want to get, before you make an actual purchase
