Product details

The ZEN C50R combines a 640 thermal sensor, 50 mm lens and integrated laser rangefinder in a clip-on built for open fields and longer shooting lanes. It adds thermal and ranging capability while keeping your familiar day optic in place.

Detailed 640 imaging for detection and identification at distance
Built-in rangefinder for fast distance checks
Compatible with selected objective adapters and aligned Picatinny setups

Best for: Predator and hog hunters who want long-range thermal performance without switching to a dedicated thermal scope.

Setup note: Confirm the adapter, centerline height and zero before hunting.

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.

IP67 Protection

Magnesium housing with an IP67 protection rating.

64GB Recording

Photos, video and recoil-activated pre-record. The virtual reticle appears in recordings only, not in the live clip-on view.

Compass & Tilt

Integrated digital compass and accelerometer.

Easy Bluetooth connection

Turn on device Bluetooth and open ZSYNC to find and connect your device, without typing a Wi-Fi password. Enjoy live view, remote controls and media downloads. Update your app and device firmware first (ZSYNC 3.0.0+; firmware V2.01+).

Compact magnesium housing

Listed device weight: 14.99 oz. Allow for the weight of your chosen adapter and mount.

Replaceable field power

Two replaceable 18350 batteries. Up to 6 hours of runtime; battery life varies with settings, temperature and use.

Bring the observation onto the map

Use your C50R rangefinder with ZSYNC to mark observation locations on the map and help revisit them. ZenTrace is now supported across all Zentron devices with built-in LRF. Update your app and device firmware before use.
