NocPix BOLT P25R Thermal Imaging Scope with LRF

The BOLT P25R uses a 256×192 thermal detector with a 12μm pixel pitch.

This is the lowest-resolution detector in the current BOLT family, which is one of the main reasons the P25R can be offered at a substantially lower price than the L35R and H50R.

It is best viewed as an accessible dedicated thermal riflescope rather than a direct alternative to a premium 640-resolution model. For shorter and medium-distance observation, pest control and straightforward thermal shooting, the P25R provides useful thermal detection while retaining the same core ranging and ballistic functionality as the more expensive BOLT models.

The 12μm pixel pitch helps keep the detector and optical system compact while supporting useful image scale through the 25mm lens.

The P25R's detector is rated at ≤20mK NETD thermal sensitivity.

NETD describes how effectively a thermal detector can distinguish very small differences in temperature. A lower figure indicates greater sensitivity.

This affects how well subtle temperature differences in animals, vegetation and surrounding ground can be separated, particularly in mild, damp, foggy or overcast conditions when thermal contrast is reduced.

The P25R and L35R are both rated at ≤20mK, while the flagship BOLT H50R improves this further to ≤18mK.

The BOLT P25R pairs its thermal detector with a 25mm F1.0 germanium objective lens.

The relatively short 25mm focal length helps keep the scope compact and gives the P25R a practical viewing area for shorter and medium-distance shooting.

Objective Lens	25mm F1.0
Field of View	7.0° × 5.3°
Field of View at 100m	12.3 × 9.2m
Base Magnification	3.5×

The P25R therefore gives a relatively focused view rather than the extremely wide scanning view associated with low-magnification handheld thermals.

The BOLT P25R starts at 3.5× magnification and provides magnification up to 14×.

The 3.5× starting magnification gives targets useful native image scale through the riflescope and suits the P25R's intended role as a compact shooting optic rather than a wide-field handheld scanner.

Higher digital magnification can be applied where a closer view is required, although—as with every thermal optic—digital enlargement reduces the amount of native detector information represented in the enlarged image.

This is also where the higher-resolution L35R and H50R begin to gain an advantage, because they have more native thermal pixels available before digital magnification is applied.

NocPix states a thermal detection range of approximately 1,300 metres for the BOLT P25R under the manufacturer's specified conditions.

This figure refers to detecting the presence of a defined heat source and should not be interpreted as positive identification range.

There are three useful concepts to separate:

• Detection – establishing that a heat source is present
• Recognition – determining the general type or shape of the target
• Identification – obtaining enough detail to positively determine what the target is

Positive identification therefore occurs at considerably shorter distances than the maximum detection figure.

Real-world performance also depends on weather, humidity, target size, thermal contrast and surrounding terrain.

One of the most important features of the BOLT P25R is that NocPix has retained a fully integrated laser rangefinder despite the scope's lower price point.

The periscope-style LRF provides ranging out to a manufacturer-stated maximum of approximately 1,200 metres under suitable conditions.

Accurate ranging is especially useful when shooting through thermal because darkness removes many of the normal visual references used to judge distance.

The range measurement is presented through the thermal riflescope, allowing the shooter to detect, observe and range without moving away from the optic or carrying a separate handheld rangefinder.

The integrated LRF works alongside the BOLT's onboard ballistic calculation system.

Once the relevant rifle and ammunition data has been configured, measured range can be incorporated into the ballistic calculation to provide aiming guidance through the display.

The system brings thermal observation, distance measurement and ballistic assistance together within the same riflescope.

Ballistic calculation remains an aiming aid. Rifle zero, ammunition data and trajectory should always be verified with the actual rifle and ammunition combination before relying on calculated corrections in the field.

The BOLT series uses NocPix's R+ image-processing algorithm to help improve the clarity and usability of the thermal image.

Image processing works alongside the detector to refine edges, improve scene presentation and make useful thermal information easier to interpret.

This matters particularly on a lower-resolution detector such as the P25R because effective processing helps extract the maximum useful information from the available 256×192 sensor.

Final thermal image quality is determined by the combined performance of the sensor, thermal sensitivity, objective lens, processing and display rather than sensor resolution alone.

The BOLT family provides 50mm eye relief together with a large 10mm exit pupil.

The 50mm eye relief allows the shooter to maintain a practical viewing position behind the scope, while the generous exit pupil makes eye alignment more forgiving.

This helps the image remain easier to acquire when mounting the rifle quickly or shooting from different positions.

Eye Relief	50mm
Exit Pupil	10mm

The BOLT P25R uses a dual-battery system designed to provide long operating time without making the user entirely dependent on a sealed internal battery.

The scope incorporates a built-in 5000mAh rechargeable battery together with a replaceable rechargeable 18650 battery.

NocPix states that the P25R and L35R can provide up to approximately 12 hours of operation under specified conditions.

Internal Battery	Built-in 5000mAh rechargeable battery
Replaceable Battery	Rechargeable 18650
Maximum Stated Runtime	Up to approximately 12 hours

The removable-battery design means a charged spare 18650 can be carried and exchanged in the field rather than waiting for the complete scope to be recharged.

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

The BOLT P25R can capture photographs and thermal video directly through the scope.

Audio recording is also supported, allowing compatible video footage to include sound.

Recoil Activated Video can automatically preserve footage around a detected shot, reducing the chance of missing an important recording because video had not been started manually.

This makes it easier to record shooting sessions, review events afterwards or transfer useful footage without requiring an external recording device.

The BOLT series supports N-LINK connectivity for compatible smartphone and wireless functions.

Supported functions include access to media and configurable scope features through the compatible NocPix ecosystem.

Wireless functionality also complements the BOLT's internal photo and video recording system by making recorded material easier to access and manage.

The P25R provides a range of configurable viewing and aiming options rather than locking the user into one fixed reticle or thermal presentation.

NocPix provides customisable reticle options, ballistic parameter settings, seven thermal colour palettes and 10 levels of image adjustment.

This allows the image and aiming system to be adapted to different environments, shooting conditions and user preferences.

Different thermal palettes can be useful for different tasks: high-contrast modes can help with initial detection while less intense viewing modes may be more comfortable during extended observation.

BOLT is deliberately designed to feel familiar to shooters moving from conventional daytime optics.

The riflescope-style body provides familiar positioning and handling rather than the compact box-shaped design used by many other thermal sights.

NocPix describes the BOLT P25R and L35R as suitable for a broad range of platforms including rifles, airguns and shotguns, subject to correct mounting and compatibility.

The integrated level platform can also make it easier to fit compatible riflescope accessories while providing a useful reference during setup.

Always use correctly sized, suitable mounts and confirm eye relief and zero after installation.

NocPix designed BOLT with practical nighttime hunting in mind.

Silent buttons help reduce unnecessary operating noise when adjusting the scope in the field, helping avoid alerting nearby animals.

The controls are arranged around the traditional riflescope format so key functions remain accessible while the rifle is shouldered.

The BOLT series uses a high-strength aluminium-alloy body with an integrated structural design intended to withstand demanding outdoor use.

The scope carries an IP67 ingress-protection rating, providing protection against dust and water exposure within the limits of the IP67 standard.

NocPix specifies an operating temperature range of approximately -20°C to +55°C and states that the BOLT platform has undergone extensive shock testing for repeated recoil reliability.

Body	High-strength aluminium alloy
Ingress Protection	IP67
Operating Temperature	Approximately -20°C to +55°C

The P25R and L35R share many of the same BOLT features including integrated ranging, ballistic calculation, ≤20mK thermal sensitivity, a 50Hz refresh rate and the dual-battery system.

The main difference is the thermal detector and objective lens.

P25R	256×192 | 25mm F1.0 | 3.5–14× | ~1,300m detection
L35R	384×288 | 35mm F1.0 | 3.5–14× | ~1,800m detection

The L35R's 384×288 detector contains approximately 2.25 times as many thermal pixels as the P25R's 256×192 sensor.

The H50R represents a substantial increase in thermal imaging performance over the P25R.

P25R	256×192 | ≤20mK | 25mm F1.0 | 50Hz | 3.5–14× | ~1,300m detection
H50R	640×512 | ≤18mK | 50mm F1.0 | 60Hz | 3–24× | ~2,600m detection

A 640×512 detector contains approximately 327,000 pixels, compared with roughly 49,000 in a 256×192 detector. The H50R therefore has well over six times as many native thermal pixels.

This gives the H50R a major advantage when viewing smaller or more distant targets and when additional magnification is required.

The P25R makes most sense for someone who wants a dedicated thermal riflescope with integrated rangefinding and ballistic calculation but does not want to spend significantly more on higher sensor resolution.

It is particularly attractive for:

• First-time thermal riflescope buyers
• Shorter and medium-distance pest control
• Air-rifle setups
• Users moving from daytime optics into thermal
• Shooters who want integrated LRF and ballistics at a lower price point
• Users who value long battery life and replaceable power

If image detail is the main concern, the L35R is the next logical step. For substantially higher-resolution performance and longer-range observation, move to the BOLT H50R.
