Whether running drills at the range or holding the line, the Defender-ST is ready when and wherever you are. Rugged and reliable? It’s a given. Large sight window? Absolutely. Motion-activation and a dot with adjustable brightness, it delivers superior target acquisition, adaptability in all lighting conditions, and faster follow-up. Experience what users mean when they discuss the ideal, all-round red dot. With the Defender-ST, you're not just range-ready, but set up with the toughness and adaptability your world demands.

Brightness Selection with the Defender-ST sight offers 12 settings (10 daylight settings and two NV settings). Adjust the dot brightness by pressing the appropriate “Up” or “Down” button.

Motion Activation is only available when the auto-shutoff feature is turned on. By allowing the unit to shut off automatically after 10 minutes, the dot will turn on automatically the next time you pick it up. Powering down the red dot manually will disable the motion activation.

Auto-Shutoff will automatically shut off the Defender-ST after 10 minutes. Powering down the red dot manually will disable the auto-shutoff feature. To engage or disengage the auto-shutoff press and hold the up and down buttons for three seconds.
