BOLT P25R – best for keeping the price down

The P25R uses a 256×192, 12μm detector with a 25mm F1.0 lens, ≤20mK sensitivity and 3.5–14× magnification. NocPix gives it a manufacturer-stated detection range of approximately 1,300 metres. :chatgpt-content-reference{index="2"}

BOLT L35R – the sweet spot

The L35R steps up to a 384×288 sensor and a 35mm F1.0 lens while retaining ≤20mK sensitivity and 50Hz operation. Detection range increases to approximately 1,800 metres. :chatgpt-content-reference{index="3"}

BOLT H50R – the premium BOLT

The H50R moves to a 640×512 sensor, improves thermal sensitivity to ≤18mK, increases the refresh rate to 60Hz and uses a 50mm F1.0 lens. Detection range rises to approximately 2,600 metres. :chatgpt-content-reference{index="4"}

The model progression is straightforward: P25R prioritises affordability, L35R adds substantially more native thermal detail and H50R makes the jump to premium 640-resolution performance.

The P25R and L35R share many of the same underlying features. Both use 12μm detectors, ≤20mK thermal sensitivity, 50Hz refresh rates, integrated 1,200m laser rangefinders and ballistic calculation.

The important upgrade is sensor resolution and lens size.

A 384×288 sensor contains around 111,000 thermal pixels compared with roughly 49,000 in a 256×192 detector. That means the L35R has approximately 2.25 times as many native thermal pixels.

The jump from L35R to H50R is larger than simply moving from a 35mm to a 50mm lens.

The H50R's 640×512 detector contains almost three times as many pixels as the L35R's 384×288 sensor. It also improves thermal sensitivity and refresh rate. :chatgpt-content-reference{index="5"}

Sensor resolution determines how many individual thermal pixels are available to build the image.

256×192

Approximately 49,000 thermal pixels. Suitable for straightforward shorter-range detection and the lowest purchase price.

384×288

Approximately 111,000 thermal pixels. A clear increase in native detail and a strong middle ground for general pest control.

640×512

Approximately 327,000 thermal pixels. Considerably more native information, helping retain target shape and detail at longer distances and under magnification.

Sensor resolution is not the only thing that determines image quality. NETD, objective lens, processing, refresh rate and display performance also matter.

NETD measures how effectively a thermal detector can distinguish small differences in temperature.

Lower values indicate greater thermal sensitivity.

The P25R and L35R are rated at ≤20mK, while the H50R improves to ≤18mK. :chatgpt-content-reference{index="6"}

This matters particularly in mild, damp, foggy or overcast conditions when an animal and the surrounding landscape may have relatively similar surface temperatures.

Resolution and NETD describe different aspects of performance: resolution affects spatial detail, while NETD affects sensitivity to small temperature differences.

Objective-lens size affects image scale, field of view and the distances at which a thermal scope feels most comfortable.

25mm – P25R

The most compact configuration and well suited to shorter and medium-distance use.

35mm – L35R

A useful middle ground that provides more reach and image scale while remaining versatile across mixed terrain.

50mm – H50R

Designed for larger fields and longer viewing distances, with the highest thermal resolution in the range to support the longer focal length.

Lens size should always be considered alongside sensor resolution rather than in isolation.

All three current NocPix BOLT models include an integrated periscope-style laser rangefinder with a manufacturer-stated ranging distance of up to 1,200 metres. :chatgpt-content-reference{index="7"}

The LRF works alongside onboard ballistic calculation, allowing measured distance to be incorporated into a calculated aiming solution once the relevant ballistic data has been configured.

This is particularly useful at night because darkness removes many of the visual references normally used to judge distance accurately.

Manufacturer-stated detection range tells you how far the thermal system can detect the presence of a defined heat source under its test conditions.

It does not mean the target can be positively identified at that distance.

• Detection – confirming that a heat source exists.
• Recognition – determining its general shape or type.
• Identification – obtaining enough detail to positively determine what it is.

Identification always occurs at a shorter distance than headline detection range, and real-world performance depends on weather, target size, thermal contrast and terrain.

The BOLT range uses a dual-battery system combining a built-in 5000mAh rechargeable battery with a replaceable rechargeable 18650 battery. :chatgpt-content-reference{index="8"}

This gives the convenience of internal power while still allowing a removable battery to be swapped during longer sessions.

NocPix specifically states up to 9 hours for the H50R's dual-battery system, while the BOLT family is rated for up to 12 hours depending on model. :chatgpt-content-reference{index="9"}

Actual runtime varies according to temperature and use of functions such as Wi-Fi, recording and laser ranging.

The BOLT platform uses NocPix's Reality+ image-processing technology to improve useful thermal detail and reduce unwanted image noise.

NocPix specifically highlights the H50R's Reality+ AI algorithm and Ultra Clear Mode as key parts of its upgraded image performance. :chatgpt-content-reference{index="10"}

Image processing is especially valuable in vegetation, woodland and other complex scenes where preserving edges and subtle detail can make a heat source easier to interpret.

The BOLT range supports onboard thermal photography, video recording and audio recording.

Recoil Activated Video can automatically preserve footage around a shot, reducing the need to manually start recording immediately beforehand.

N-LINK app connectivity provides compatible wireless functionality, while BOLT also offers configurable reticles, ballistic parameters, seven thermal colour palettes and 10 levels of image adjustment. :chatgpt-content-reference{index="11"}

BOLT is aimed at users who want a straightforward dedicated thermal riflescope without giving up features that might normally be associated with more expensive ranges.

• Traditional riflescope-style layout
• Three sensor-resolution levels to suit different budgets
• Integrated 1,200m laser rangefinder on every model
• Ballistic calculation on every model
• Dual-battery power system
• Photo, video and audio recording
• Recoil Activated Video
• N-LINK connectivity
• Customisable reticles and ballistic settings
• IP67 protection
• High-strength aluminium-alloy construction
• Silent buttons for field use

NocPix positions BOLT as an accessible route into dedicated thermal riflescopes, but the H50R in particular provides a genuinely strong specification with 640×512 resolution, ≤18mK sensitivity and 60Hz performance. :chatgpt-content-reference{index="12"}

NocPix BOLT

Best suited to users wanting strong value, conventional riflescope handling and integrated LRF/ballistic features without immediately moving into NocPix's premium scope ranges.

NocPix ACE

A more premium riflescope family with higher-end viewing systems, more advanced optics and models extending all the way to 1280×1024 resolution.

NocPix ACE 2

The newest premium ACE generation, adding ≤12mK thermal sensitivity, upgraded image processing, Ocular Zoom 2.0, LRF 2.0, Ballistic Calculation 2.0 and lighter magnesium construction.

Shorter-range pest control and smaller ground

The P25R makes the most sense when budget is important and targets are generally encountered at shorter or medium distances.

Mixed ground

The L35R is the strongest all-round compromise. Its 384×288 sensor provides a useful increase in detail while its 35mm lens remains versatile.

Large fields and open terrain

The H50R is the clear choice. Its 640×512 sensor, 50mm objective, ≤18mK sensitivity and 60Hz refresh rate give it the best longer-distance performance in the BOLT range.

NocPix applies separate warranty periods to the main device, rechargeable batteries and thermal detector.
