A thermal monocular to observe far and measure accurately
The CONOTECH Aquila Pro 650 LIIR is aimed at the hunter who seeks more than just a simple thermal image.
Its sensor VOx 640×512 at 12 µm, combined with a lens of 50 mm, provides a detailed image with a native magnification of 2.7×. The zoom then allows up to 14× to refine observation as the distance increases.
But the uniqueness of this version lies elsewhere: the LIIR laser rangefinder is directly integrated into the monocular.
CONOTECH uses a patented design aimed at maintaining alignment between the laser axis and the infrared axis. In the field, this allows measuring the distance to the observed point without having to switch from one device to another.
For hunters
If you regularly observe at medium or long distances, the integrated rangefinder provides an important additional piece of information: the actual distance to the point you are looking at.
This is particularly interesting when observing from a lookout, during an approach, or when the terrain makes distance estimation misleading. The goal is not to multiply functions, but to consolidate useful information for decision-making in the field into a single device.
How to use the Aquila Pro 650 LIIR?
1
Turn on and adjust
Power on the monocular, adjust the eyepiece to your vision, and set the focus.
2
Observer
Search your observation area and use the zoom up to 14× to refine the details.
3
Measure the distance
Activate the LIIR laser rangefinder to quickly know the distance to the observed point.
4
Record
Capture your observations in photo or video and find them later via the 64 GB of internal memory.
How to use the Aquila Pro 650 LIIR?
A 640×512 sensor in 12 µm
This configuration aims for accurate reproduction of thermal differences, especially when the thermal contrast becomes less pronounced.
A 50 mm lens for distant observations
The 50 mm combined with a native magnification of 2.7× gives the Aquila Pro 650 LIIR a profile suitable for medium and long-distance observations.
A directly integrated laser rangefinder
No need to pull out a separate rangefinder to know the distance to the observed point.
One-handed use
This is a detail that becomes important as you progress, whether you are observing from a position or need to keep the other hand free.
A power supply designed for long outings
The Aquila Pro combines a built-in battery with a removable 18500 battery. The external battery can be replaced without interrupting the device's operation.
A device designed for the field
With an IP67, an operating range of -20 °C to +50 °C and a weight of 560 g, the Aquila Pro 650 LIIR remains compact enough to be carried in a bag or used during an extended outing.
Who is the Aquila Pro 650 LIIR monocular for?
I recommend it if:
- you are looking for a high-end thermal monocular for observing at a distance;
- you want to have a built-in laser rangefinder rather than using two separate devices;
- you regularly practice stalking, approaching, or night observation;
- you value the accuracy of the thermal image;
- you want to be able to measure a distance directly from the observed image;
- you wish to maintain good battery life for long outings.
It is less suitable if:
You are primarily looking for a very compact and lightweight monocular for close observations. With its 50 mm lens and 560 g, the Aquila Pro 650 LIIR is more oriented towards distant observation than towards finding a minimalist device.

Valentin's opinion
I chose the Aquila Pro 650 LIIR for a simple reason: it combines a true thermal optic and an integrated rangefinder in one monocular. On the field, I prefer to have distance information directly in the device rather than multiplying the manipulations with several pieces of equipment.
I especially recommend it to the hunter who regularly observes at a distance and wants a precise, robust, and complete tool without wasting time changing devices.
To remember
The CONOTECH Aquila Pro 650 LIIR is a thermal monocular designed for hunters who prioritize distance observation and want to have a distance measurement directly in their optics.
Its sensor 640×512 / 12 µm, its objective 50 mm, its magnification 2.7× to 14× and its OLED screen 1024×768 provide a solid foundation for thermal observation. Its true field interest, however, remains the integrated LIIR laser rangefinder, capable of measuring up to 1,200 m with an announced accuracy of ±1 m.
In addition, it features 64 GB of storage, Wi-Fi, photo/video recording, dual battery power, and an IP67 construction.
If you are looking for a complete thermal monocular to observe far, identify accurately, and know the distance to the observed point without pulling out an additional device, the Aquila Pro 650 LIIR clearly deserves consideration.
FAQ - Frequently Asked Questions
Both models use the same 50 mm optical base, with a 640×512 sensor and a magnification of 2.7×. The version 650 LIIR adds the integrated laser rangefinder, capable of measuring up to 1,200 m.
Yes. The system combines a built-in battery and a removable 18500 battery. CONOTECH states that the replacement of the external battery can be done without interrupting the operation of the monocular.
Yes. The manual provides for a simple measurement mode as well as a continuous measurement mode (scan). The measured distance can be displayed directly on the thermal image.
Yes. The eyepiece has an adjustment mechanism to adapt the observation, especially for users wearing glasses.
Yes. Its protection rating IP67 protects it against dust and temporary immersion. It is designed to operate between -20 °C and +50 °C.
The main advantage of the 650 LIIR is to combine thermal observation and distance measurement in a single device.. This way, you avoid switching from a monocular to a separate rangefinder when you want to know the distance to an observed point.
Yes. The LIIR rangefinder is integrated into the monocular. You can therefore measure the distance to the observed point without using an additional device.
