I'm a new birder and have a pair of 8x binoculars which have been really great for most situations. But every now and then there's a bird that's just too far away to see properly let alone attempt to identify. I don't want to be carrying around a tonne of gear so a spotting scope is not an option. I was thinking of getting a monocular at about 20x magnification. I know at that zoom the image will be somewhat wobbly, I wish I could go in a store and physically try them out to get an idea of just how wobbly it would be, but I don't know when that'll be possible. I was wondering what more experienced bird watchers use in addition to their regular binoculars?
