Out-of-the-Box Thermal Accuracy with Integrated Rangefinding

The Leica Calonox 2 Sight LRF is a precision-built thermal sighting camera designed and manufactured entirely in Germany. Its fully integrated laser rangefinder reaches out to 1,200 meters, activated via the device or optional remote control. The European LYNRED sensor combined with Leica's LIO™ image processing delivers sharp, high-contrast thermal images. No individual rifle calibration is required — mount it and hunt. The fiberglass-reinforced housing with silicone armoring makes it field-tested and wilderness-grade for demanding night hunts. Dual-use capability means it works as a sighting optic and observation tool.

Ranging and Thermal Imaging in One Field-Tested Unit

Ranging and Thermal Imaging in One Field-Tested Unit

The $2,000 mistake in thermal optics usually looks like a separate rangefinder that fumbles in the dark, or a thermal unit that needs rifle-specific calibration before every hunt. The Calonox 2 Sight LRF eliminates both problems — 1,200-meter ranging is built into the thermal housing, activated by touch or optional remote, and the unit requires zero rifle calibration. Swap it between rifles out of the box. At Hunt Premium, we don't list optics we wouldn't bet a $3,000 tag on. This unit earned its spot because it removes the setup friction that costs hunters shots in the field.

LYNRED Sensor With Leica Image Processing for Night Hunting Clarity

LYNRED Sensor With Leica Image Processing for Night Hunting Clarity

The LYNRED European sensor combined with Leica's LIO image optimization software delivers sharp, high-contrast thermal images in low-light conditions where standard glass goes dark. For night hunters running hogs or predators, this means distinguishing target from background at distance when ambient light is zero. The large field of view keeps you oriented when game moves through cover, and the compact ergonomic shape keeps the unit manageable on a riflescope setup like the Leica Fortis 1.8-12x42 i. Season-proven image quality that doesn't degrade in rain or cold — fiberglass-reinforced housing with silicone armoring handles real field conditions.

Dual-Use Capability for Sighting and Standalone Observation

Dual-Use Capability for Sighting and Standalone Observation

Most thermal units sit in a case between hunts. The Calonox 2 Sight LRF serves double duty — mount it on your rifle for night hunting, then pull it off for standalone observation when you're glassing for sign or scanning timber before first light. No calibration step between uses means you're not fiddling with settings while shooting light burns off. The intuitive button layout and fast startup keep transition time to seconds, not minutes. For hunters who run multiple rifles or switch between day glass and thermal setups across a season, this trail-ready flexibility eliminates the single-purpose optic problem.

Rifle Compatibility

The Calonox 2 Sight LRF mounts in front of your existing riflescope and swaps between rifles without recalibration.

  • Swaps between rifles with zero recalibration needed
  • Pairs with standard hunting riflescopes (e.g., Leica Fortis 1.8-12 x 42 i)
  • Activates LRF via onboard controls or optional remote

“I've run separate rangefinders on night hog hunts for three seasons — always fumbling between two devices when a sounder pops up at 200 yards. Swapped to the Calonox 2 Sight LRF this past fall. Ranging is inside the thermal, one-button activation, and I can move it between my AR and my bolt gun with no recalibration. First night out, I had three hogs on the ground before my buddy with the separate unit even got a range. The image clarity from the LYNRED sensor is noticeably sharper than my previous thermal at 300-plus yards in zero ambient light.”

The new Leica Calonox 2 Sight LRF 50510 thermal sighting camera is not just a further development – it’s a genuine benchmark in terms of design and function. Completely designed and made in Germany, it wins users over with its compact ergonomic shape, practical, intuitive buttons, and the world’s first fullyintegrated laser rangefinder (LRF), which can be activated very easily – either on the device, or via optional remote control. The high-quality European sensor from LYNRED, together with Leica’s proven image processing software (Leica Image Optimization – LIO™) ensures even sharper images, rich in contrast and detail. What’s more, the Calonox 2 Sight LRF no longer needs individual calibration, but can be used out-of-the-box and swapped between rifles.

Frequently Asked Questions

When you're running hogs at night with a separate rangefinder, you're handling two devices in the dark, losing target acquisition time, and introducing fumble points. The Calonox 2 Sight LRF puts 1,200-meter ranging inside the thermal housing — one activation, one hand, one line of sight. For hunters who've missed shots because they couldn't get a range in time, that integration pays for itself in one season. We can walk you through whether it fits your specific night hunting setup on a free consult.
Yes. Hunt Premium is an authorized Leica dealer, which means your Calonox 2 Sight LRF carries full manufacturer warranty support. Buying from unauthorized sellers — including major online marketplaces — can void that warranty on a German-made thermal unit at this price point. We confirm authorized status on every product we sell, and our technical team is available before and after purchase if you need setup guidance or warranty support.
That's the core advantage. Unlike most thermal clip-on or standalone units that require rifle-specific calibration, the Calonox 2 Sight LRF works out of the box with no calibration step. Move it from your night hunting rifle to a backup, or use it as a standalone thermal spotter — no zeroing, no menu adjustments, no wasted time. If you want to confirm mount compatibility with your specific rifles, our pre-purchase consult covers that at no charge.
The housing is fiberglass-reinforced plastic with silicone armoring — built for the kind of handling that night hunting demands: mounting and dismounting in the dark, riding in a truck bed, sitting in a wet blind. Leica designed and manufactured this unit entirely in Germany, and the build reflects that standard. We stock it because it holds up across seasons of hard use, not because it looks good in a product photo. Call us if you want specifics on how it performs in cold and wet conditions.
The Calonox 2 Sight LRF is ready for use within seconds of switching on. For night hunters, that matters — you're not waiting thirty seconds to a minute for a thermal to boot while a coyote or hog moves out of range. Fast startup combined with the intuitive button layout means you're operational quickly when game appears. If you're comparing boot times across thermal units for a specific hunting scenario, our technical team can walk you through the details.
Dual-use capability is built in. Mount it on a riflescope like the Leica Fortis 1.8-12x42 i for night hunting, or use it as a handheld thermal observation device for scanning timber, locating game sign, or glassing before daylight. The no-calibration design makes switching between roles seamless — pull it off the rifle and start scanning. If your hunting involves both night shooting and pre-dawn observation, this covers both without buying two separate thermal units.
