In today’s world, riflescopes are more advanced than ever. When speaking of riflescope performance, most are judged by their overall light transmission but not all light transmission is equal. It’s not enough to merely have a high percentage of light transmission because most riflescopes are optimized to transmit midday light, when light transmission matters least. This is how so many optics companies can claim such high percentages of light transmission. It is for this reason that Leupold optical engineers worked diligently to redesign one of the greatest scopes of all time into the all new VX-3i.
The VX-3i is built around Leupold’s new Twilight Max Light Management System which balances all available light wavelengths, eliminates glare, and pushes resolution to the limit. Beginning with lead-free lenses, Leupold applies Twilight Max lens coatings. These coatings optimize the red and blue frequencies of light, those found at the very first and last moments of the day, while maintaining a high transmission of the light at the center of the spectrum, delivering exceptional contrast and low light performance. These lenses are then topped off with Diamondcoat 2 for the highest level of abrasion resistance. The next step is the elimination of glare. Although not often said, this step actually lowers overall light transmission by removing or absorbing stray light, only transmitting useful light to your eye, creating an improved sight picture. This is accomplished by first precision machining the VX-3i’s interior and then by blackening the edges of key lenses within the scope.


Unlike other systems that use generic ballistics information to generate equally generic drop data, the CDS uses the shooter’s unique ballistics and environmental conditions to calculate true custom drop values that are laser engraved onto the dial. The first step in getting this done is to determine the best load for the rifle. Since no two guns will shoot the same load identically, it is important to get the most accurate ballistic data possible. Since the CDS system will be as accurate as the information the shooter supplies to Leupold, loads should be chronographed and the elevation and temperature, +/- 2000 feet and +/- 20 degrees Fahrenheit respectively, should match the intended use area. Leupold will need the following data, cartridge, bullet type, bullet weight, ballistic coefficient, muzzle velocity, average altitude, average temperature and sight height. The CDS will have a 100 or 200 yard zero in most cases (determined by the customer), then read in 50 yard increments out to the maximum yardage that can be reached in 14.5 minutes of angle (MOA). The CDS dial itself is a one turn dial with a built in zero stop. This allows the shooter to come back to zero without looking or counting clicks.

When these two state of the art technologies are combined, hunters and shooters are armed with the best possible tools to achieve long range first shot hits.
It took Leupold to bust the myth of “light gathering” optics and turn the conversation to light transmission. Now prepare to hear a lot more about light management, as the rest of the industry tries to catch up to the new VX-3i. Check out the new Leupold VX-3i at your local Sportsman’s Warehouse today.
