Windie 8x42 Marine Monocular with Compass

The Windie Marine Monocular does the job of three instruments without asking for a second hand. Look through it and you get eight times magnification, a compass bearing along the bottom of your view, and a scale that turns any object of known height into a distance. It weighs 340 grams, it is waterproof, and it works with your glasses on. Built for sailors, race officers and coaches who need an answer now and cannot put down what they are holding.

• 8x magnification with a compass bearing in view
• BaK-4 glass prism for a sharp, bright image, not plastic
• Distance scale in view, no batteries
• Waterproof, one hand, works with your glasses on
