A couple of general notes, as I've been using various RF binoculars for more than a decade:
The image won't be quite as good as through the same company's non-RF binoculars of the same grade, because the RF stuff inside tends to scatter the light slightly. But it will be close--and with really good brands will still be VERY good.
Often RF binoculars will work at very close ranges (as for bowhunting) IF you push the barrels as close to each other as possible. The reason they often don't work under 30 yards or so is the laser beam comes out of one barrel, then bounces back to the other barrel. With the binocular used normally, with the barrels set for both our eyes, the returning beam often misses the receiving barrel. But when the barrels are pushed close together, they'll often read down to 10 yards or so.
