when the vx3 was introduced, these are some of the changes they mentioned.
Leupold is making the following claims for the new vx3 scopes:
-The Xtended Twilight Lens System™ optimizes the transmission of low-light wavelengths, so you see the details of low-light scenes in greater, brighter detail than with any other riflescope available.
-DiamondCoat 2™ lens coatings on exterior lens surfaces provide the highest level of scratch resistance Leupold has ever offered.
-The twin bias spring exerts up to 30 percent more holding force on the erector, virtually eliminating erector system backlash and stress on the vital internal workings of the scope, for longer life.
-Blackened lens edges reduce light diffusion, so more usable light reaches the shooter’s eye, for a brighter image with increased contrast.
Illuminated models feature second generation LED technology, nearly twice as bright as previous models, with multiple intensity settings for precise shot placement in low-light situations.
-A durable Leupold Scope Cover is included to protect your valuable VX-3 riflescope during transport or when not in use.
-Incredibly rugged, with absolute waterproof integrity using Leupold's proprietary Argon/Krypton gas blend.
