Solar Power Meets 150,000 Hours of Runtime
At the core of the SPARC Solar is Vortex's Auto D-TEC system, an innovative power-management feature that dynamically switches between solar and CR2032 battery inputs based on ambient light levels. The result?
- Up to 150,000 hours of runtime.
- Seamless transition between lighting conditions.
- Always-on readiness—whether you're on patrol at noon or navigating a breach at midnight.
Why It Matters: This optic doesn't just extend power. It eliminates failure points and keeps you on target—always.
Tactical Precision with a 2 MOA Red Dot
The daylight-bright 2 MOA reticle offers razor-sharp aiming without obstructing your view. It's engineered for:
- Fast target acquisition at close range.
- Pinpoint accuracy at distance.
- Night-vision compatibility for low-light or covert ops.
With 10 brightness settings—two of which are night-vision-ready—you're equipped for every mission scenario.
