Bino for home birding

I got to use Pentax Papilio bino on a San Bernadino Audubon field trip to Big Bear Lake area(the leaders kindly loaned me one), and it was quite good, for such a small size.

Was it this

Or this;

So I thought of buying one, and bought a cheaper UCFR for half a price.

And having used it for some time; really not bad at all, and it being so small, you can just whip it out from your jacket or hoodie pocket and do instant birding anywhere!

Of course not enough FOV, but I've spotted Townsend's and Orange-crowned warblers inside the canopy at downtown East Pasadena using it one handed! So handy.

Heartily recommend those for easy and quick birding.
