I just can't buy binoculars or monoculars based on a suggestion. Everybody sees things differently. I was at a sports store testing binoculars. I found some inexpensive Humvee 20x50 binoculars on sale for $20 (regular $40 or so). I couldn't believe it when I was testing them out. I thought I was doing something wrongly, but the salesperson just said everybody's eyes are different. Since then, I only buy binoculars, monocular, ski goggles, and other eye gear after I've tested it out in person.

By the way, on that day I bought those inexpensive binoculars, my original intent was to buy a monocular. I was less than pleased with the performance of any monocular on display. Using binoculars is a much more enjoyable experience. I'd rather lug around binoculars or nothing, rather than a monocular.
