In reply to Chopper:
I've had several pair of small binos - and always break them. The last pair was quite decent (Nikon), but now the two halves point in different directions. I always spend more time getting the two halves matched to my eyes and then focusing on whatever it was, and then shuggling them around so that each half is aligned with the right part of my eye so that I have a halfway decent image.
I've given up now and splurged on a monocular. Keep it simple. Small, convenient and rucksack proof, and gas filled so that it won't fog up on the hills in winter. Small enough to go in the breast pocket of a softshell jacket.
8x is hard enough to hold still to look at something a long way away. 10x is harder. Anything more than that needs support. Unsurprisingly, monoculars are cheaper, and lighter and smaller.
The only pair of binoculars I ever got on with was a large pair of 10 x75 auto-focus ones which were stupid expensive and belonged to the Queen. I broke those too - drove into a very big ditch at night with them around my neck.
