I use Pentax 20x60 PCF WP, Pentax 20x60 PCF WP II, Tento 20x60 (USSR), Spectrum I 20x65 (Japan),
Orion 20x70 Little Giant II (Japan), & Burgess Optical Series II 20x90.
I sent an acquaintance of mine my vintage, discontinued, Swift 20x80 Satellite (Japan).
I also gave my neighbor an older, discontinued, FOCAL/Kmart 20x60 (Japan).
I have also used a cheap NcStar 20x70, however, after loaning it to my boss, who is also a hunter, he did not want to give it back to me.
He uses it from his truck window for spotting. I'm glad that he enjoys glassing with it.
All of the ones that I have listed are older, discontinued models, with the exception of the Pentax PCF WP II & the NcStar.
Pentax is the only one making a 20x binocular that is waterproof & fogproof and rugged enough for hunting purposes.
Just my way of saying that I prefer two-eyed viewing to squinting through a spotting scope.
Now you know of a few other 20x brand names.
