The problem is YoBuck that the op has used top quality scopes in 15 power range and he could not see well enough. How does he figure the bino's will help him. He needs the proper corrective lenses for his eyes to see any better. This is whether he stays with 10x bino's or goes to 12 or 15 power. I can only guess but a 200 dollar pair of glasses would likely solve his whole problem.
It goes without saying that his eyes should be corrected first, as he wont get proper results till he does regardless of the optics he chooses. Ive been there and done it and have seen the difference eye surgery makes. But he is fully aware of that, so it's a non issue at least here.
Comparing optics as most of us do during normal daylight hours works well, but apparently not for those who are trying to squeeze out the very last bit of light there is. Most of us are looking for what we feel to be the best image from the optics we use.
And thats where the argument over buying the best enters into the mix.
But I can well understand and also attest to the fact that sometimes we don't need the best and clearest view, we just need to know what were looking at.
And thats what the OP is looking for.
I mentioned having numerous sets of spotting scopes in brackets, which the vast majority of all PA long rangers use for hunting. I also mentioned having 15, 20 30 and 40x eyepieces for my 77mm
Kowas. I will as a rule use the lowest power I can get by with because of clarity, and that is 15x.
But on some days especially at longer distances, ill use the 20 or 30 wide angles, and especially for calling hits when were shooting. The 40xs never get used except for one reason, that being to identify. Sometimes a deer might be laying at a long distance away in thick laurel, or they might be partially obscured by trees, and you can stare at them for an hour without knowing what it is.
Put the 40s in and your looking thru a fishbowl compared to the 15s or 20s, but all you need is a small glimps when it moves its head, and you've got him. Or you can chalk it up as a doe, and move on.
And thats due to the advantage of having the power when you need it.
