You don't need a pair of binoculars for a quick look at the game, the birds on the verandah, or the boat out on the bay. You need something that fits in your pocket, has one knob to twist, and won't let you down when a drizzle rolls in. This 8x21 monocular is 25mm wide, 105mm long, and water-resistant (not fully waterproof — keep it out of the surf). 10.5mm eye relief means you can see clearly even with glasses on. Supplied with a nylon case and a polishing cloth so the lens stays clear. One knob. No fiddling. Just look. Add to cart and it's in your bag by the weekend
