Compact & lightweight

Magnesium housings keep the Q Series compact. Q50R weighs 473.7 g (16.71 oz); Q635R and Q35R each weigh 444.8 g (15.69 oz).

Extra-long battery life

Two 18350 batteries deliver up to 6 hours of continuous operation on Q50R and Q635R, or 7 hours on Q35R. Each unit comes with four rechargeable batteries and a charger.

Media library

View, organize and manage images and videos directly on the device, making it easy to select, share and analyze recordings in the field.

Silent operation buttons

Designed for discreet hunting and tactical use, the buttons minimize sound to avoid alerting game or disturbing the environment.

Pre-record

Connect to the ZEN LINK app to automatically transfer videos captured before and after the shot to your phone.

Ranging and app-configured ballistics

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

Available only on devices equipped with a laser rangefinder (LRF).
