Irving, I had a chance to fool around with the Sig2200 binoculars at a recent Rex Defense class. They were amazing! Bright, clear picture, quick to focus, and easy to hit the ranging target far away, even unsupported. Rex (Tiborasaurus) said he used it for well over 3,000 yards with fresh batteries. For the price, they seem like a great value to me. Never used the Vortex product, so I can't compare the two.
