Gentlemen, If you haven't checked out the main page lately, here's the link to our latest feature--a very lengthy guide to premium Laser Rangefinders, including a TECH section. http://www.6mmbr.com/rangefinders.html The Swarovski came out on top, but we've provided some darn good reasons to spend less on competing products if you don't need 1200+ yard ranging. Thanks to Chris Matthews for writing up his field tests with a half-dozen sample in the Wyoming high country. This tome is over 8000 words, and probably represents 70 man-hours,not counting field testing time). But I guarantee you'll learn something new,hint: beam divergence is key).
