640 detail for open ground

The C50R pairs a 640 × 512 sensor with a 50 mm f/1.0 objective lens. Built for hunters who want more thermal detail across fields, pastures and open country.

Add thermal to your day optic

Fit the factory-collimated clip-on ahead of a compatible day scope. Use the correct objective adapter or aligned Picatinny setup, then verify fit, optical alignment and zero before use.

Ranging and app-configured ballistics

Check distance with the integrated laser rangefinder. Configure your ballistic profile in ZSYNC and use the saved parameters with range data for ballistic calculation. Select the correct profile and verify your setup before use.

Menus that fit your day optic

Easy Mode emphasizes frequently used functions with larger icons and text. UI Zoom lets you adjust menu size to suit your day-scope view.
