The VX-3HD delivers outstanding performance in low light. With Leupold’s Elite Optical System, the VX-3HD delivers excellent dawn-to-dusk light transmission for a bright image when it matters most, elite-level glare reduction in harsh light, and the resolution and clarity that diehard hunters and shooters demand. We also gave it match-grade repeatability and ergonomic controls that are easy to read and use, even with gloves. The VX-3HD is the best lightweight, low-light hunting scope in its class. And with its low-profile, one-revolution CDS® ZeroLock® dial, you can be confident your dial will only move when you want it to. Push the button to unlock it, dial, and then rotate it back to zero to lock it in place. It’s that simple.
