BudsGunShop.com - CDS Systems

This comes with one. In terms of calibers, there is no caliber. That’s why it’s a CDS. You send the info to Leupold and they custom make one for your particular load. You have to pay for extras, such as if you want to use the scope on a .270 then want to use the scope on at 338 Lpaua Magnum. The 270 CDS will not function properly on with a 338LM rifle and visaversa. Every Leupold riflescope with "CDS" in the description is eligible for one free custom dial. Additional CDS dials can be purchased for only $80 from Leupold.

I bought a not so expensive Leupold scope with CDS and it comes with the one. If you want another custom dial you would have to contact Leupold. It is worth it 100%

Michael, one CDS-ZL2 dial is included. ***Important*** - Also all VX-HD riflescopes are CDS capable allowing you to send away to Leupold for a custom ballistic dial matched to your specific load and rifle.
