N-Vision Optics NOX-18 1-8x18mm Thermal Monocular Review

First Impressions of N-Vision Optics NOX-18 1-8x18mm Thermal Monocular

The N-Vision Optics NOX-18 1-8x18mm Thermal Monocular arrived, promising cutting-edge thermal imaging in a compact, versatile package. Manufactured by N-Vision Optics, this unit boasts a 12-micron 640×480 thermal core, a 60Hz refresh rate, and the ability to be weapon-mounted or used as a handheld scanner. The potential for bridging with my existing PVS-14 night vision monocular was particularly appealing.

I’ve been searching for a thermal optic that could truly enhance my capabilities during nighttime hog hunts and search and rescue operations. My aging FLIR Scout TK just wasn’t cutting it anymore. I needed something with greater range, clarity, and the ability to integrate with my existing gear.

Upon unboxing, the NOX-18 feels incredibly solid. The housing seems robust, and the controls are intuitively placed. The unit has a surprising heft, lending to its impression of durability, while still feeling manageable for extended use.

I was considering the Pulsar Helion 2 XP50 Pro and the Bering Optics Hogster Stimulus, but the N-Vision Optics NOX-18 offered a superior combination of size, weight, and image clarity for my specific needs. The ability to run on both CR123 batteries and rechargeable 18650s also sealed the deal. I was immediately impressed and eager to get it into the field.

Real-World Testing: Putting N-Vision Optics NOX-18 1-8x18mm Thermal Monocular to the Test

First Use Experience

I tested the N-Vision Optics NOX-18 during a nighttime hog hunt on a sprawling ranch in central Texas. The area offered a mix of open fields, dense brush, and wooded areas, providing a good variety of environments. I experienced temperatures ranging from a comfortable 65 degrees Fahrenheit to a slightly chilly 50 degrees Fahrenheit.

The NOX-18 performed exceptionally well in all conditions. The thermal clarity was outstanding, easily detecting hogs out to 300 yards in open fields. Even in dense brush, the thermal penetration allowed me to spot animals that would have been completely invisible with traditional night vision. I found the button layout intuitive and easy to use, even while wearing gloves, and the manual calibration button proved invaluable.

I didn’t anticipate needing to recalibrate the image so frequently, but it became second nature after a few uses.

Extended Use & Reliability

After several months of use, the N-Vision Optics NOX-18 continues to impress. I’ve used it on numerous hog hunts, search and rescue training exercises, and even a few late-night wildlife observation sessions. It still delivers exceptional thermal clarity, and its rugged construction has proven resilient to the bumps and bruises of field use.

The unit shows no significant signs of wear and tear, despite being subjected to dirt, dust, and moderate rain. Cleaning is simple; I just wipe down the lens and housing with a clean cloth after each use. Comparing it to my older FLIR unit, the NOX-18 is in a completely different league, offering superior range, clarity, and overall performance.

Breaking Down the Features of N-Vision Optics NOX-18 1-8x18mm Thermal Monocular

Specifications

The N-Vision Optics NOX-18 1-8x18mm Thermal Monocular boasts impressive specifications. It includes:

• A 640×480 12-micron Thermal Core: This high-resolution sensor provides exceptional image clarity and detail.
• A 60 Hz Refresh Rate: This provides a smooth, real-time image, crucial for tracking moving targets.
• An 18 mm Objective Lens: Offers a good balance of magnification and field of view.
• 1-8x Magnification: Allows for both wide-area scanning and close-in identification.
• 30.4-degree Field of View: Provides a wide area of coverage for scanning large areas quickly.
• Picatinny Mount: Enables weapon mounting for increased tactical applications.
• Multiple Battery Options (18650, CR123, USB): This provides flexibility and extended run time in the field.
• A weight of 16 oz. A surprisingly lightweight for a thermal scope

These specifications translate directly to enhanced performance in the field. The high-resolution core and fast refresh rate provide a clear, smooth image, while the variable magnification allows for both wide-area scanning and detailed observation. The multiple battery options ensure that the unit can be powered for extended periods, a critical factor during long hunts or search operations.

Performance & Functionality

The N-Vision Optics NOX-18 excels in its primary function: detecting heat signatures at extended ranges. The image is remarkably clear and detailed, allowing for easy identification of animals, humans, and other heat sources. The variable magnification is smooth and precise, and the manual focus allows for fine-tuning the image to achieve optimal clarity.

The NOX-18 excels in its role as a thermal imager. However, the image can degrade slightly over time, requiring manual NUC (Non-Uniformity Correction) to reset the sensor, but this is quick and easy with the dedicated button. There is also a very slight digital delay in what you see due to the digital display.

Design & Ergonomics

The build quality of the N-Vision Optics NOX-18 is exceptional. The housing feels solid and durable, and the controls are well-placed and easy to operate. The unit is also surprisingly lightweight for its size, making it comfortable to hold for extended periods.

The ergonomics are well-thought-out. The buttons are easily accessible, even with gloves, and the menu system is intuitive and easy to navigate. The NOX-18 features an adjustment for right or left-eye use, which makes it usable by most people.

Durability & Maintenance

The N-Vision Optics NOX-18 appears to be built to last. The rugged housing and high-quality components suggest that it will withstand years of use in demanding environments. Maintenance is minimal; simply wipe down the lens and housing with a clean cloth after each use.

With a waterproof rating, the NOX-18 is equipped for the elements.

Accessories and Customization Options

The N-Vision Optics NOX-18 ships with a standard CR123 battery, a rechargeable 18650 battery, and a charger. The unit is also compatible with external USB battery packs for extended run time. The Picatinny mount allows for easy weapon mounting, and the removable mounts further reduce the size and weight of the unit.

The weapon and/or dovetail mounts are removable, allowing for the unit to be customized for the user’s specific needs. Additionally, the unit can be bridged with a PVS-14.
