Instead of arguing which bird binoculars are the best, take a look at what birders are actually using. Take a look and talk with the birders. Ask them why they selected the binoculars they purchased. Sometimes it is a matter of price or convenience.
I bought a compact pair of Audubon binoculars (see review below) one summer when I discovered my camera and binoculars were accidentally left on the kitchen table about 900 miles away from my vacation spot.
I also bought a new birding guide for all the shore birds I expected to observe during my trip. (See details below). My time was short and my sources were limited, so I decided to buy the best name brand that was available at the store where I stopped.
