Custom Dial System (CDS)
Hold Dead On. Hit Dead On.
Leupold’s Custom Dial System® (CDS®) helps you easily compensate for bullet drop and make ultra-quick adjustments on the fly. We’ll customize your scope’s elevation dial to match your exact load, velocity, and conditions for unprecedented precision. Once you range your target, simply turn the dial to the correct position, aim dead on, and squeeze the trigger.
Dead-on Hits, Every Time, Without the Holdover
Every CDS dial features ¼-MOA click increment finger adjustments and no adjustment covers to lose, making the VX-2, VX-3, VX-3L, VX-6 and VX-R even more accurate and rugged.
The CDS System works by laser-inscribing your scope’s elevation dial to match your load, velocity and conditions. Your scope will be in perfect synch with the way your rifle and load shoots, even for hand loads.
Each CDS dial is unique, taking all practical ballistic and environmental factors into account:
- Cartridge & Caliber
- Bullet Weight
- Bullet Make/Brand
- Bullet Type
- Ballistic Coefficient
- Muzzle Velocity
- Average Elevation
- Average Temperature
- Quickly dial in elevation to different sight-in ranges.
- Swap dials quickly by loosening set screws.
- Match dials with specific loads for maximum accuracy.
- Precision ¼-MOA click increment adjustment.
- No adjustment covers to lose.
- One revolution stops available for custom dials.
- Use in tandem with Leupold’s RX rangefinder family for unmatched long-range precision.
- Zero in Distance (yds/meters)
- Height of scope center above rifle bore center
- To measure scope height, place the bottom of a ruler at the approximate center of the bolt. Measure from this point to the center of the scope tube. A typical hunting rifle will measure between 1.5-1.75″ and an AR platform measurement will typically be 2.75″.
