The best VISTA depends mainly on whether you prioritise wide-area scanning, longer-range observation, laser ranging or maximum thermal image quality.

The biggest difference between the H35 and H50 models is the objective lens.

The 35mm VISTA H35 and H35R provide a wider 12.5° × 10° field of view and 3× base magnification. This makes them particularly effective for quickly scanning woodland, hedgerows, mixed terrain and closer-to-medium-distance environments.

The 50mm VISTA H50 and H50R provide 4× base magnification and a narrower 8.8° × 7° field of view. Distant heat sources therefore appear larger before digital zoom is applied.

On the NocPix VISTA range, the R identifies models fitted with an integrated laser rangefinder.

The H35 and H35R share the same core thermal sensor, lens and field of view. Likewise, the H50 and H50R share the same core thermal platform.

The R versions add integrated laser ranging so you can measure target distance directly through the thermal monocular without carrying a separate handheld rangefinder.

The VISTA S50R represents a substantial step up from the H50R because its thermal detector has a much higher resolution.

The H50R uses a 640×512 sensor, while the S50R uses a 1280×1024 sensor. This means the S50R contains roughly four times as many thermal pixels.

Both models use a 50mm F0.9 objective lens, but the larger S50R sensor allows it to deliver a much wider 17.5° × 14° field of view compared with the H50R's 8.8° × 7°.

The S50R therefore gives you both a larger viewing area and substantially more thermal image information.

Thermal sensor resolution determines how many temperature-measuring pixels are used to build the image.

A 640×512 detector contains 327,680 thermal pixels and already provides excellent image quality for a premium handheld monocular.

A 1280×1024 detector contains more than 1.3 million thermal pixels. That gives the VISTA S50R roughly four times as much thermal image information as the 640×512 H-series models.

The practical advantage is more detail, a wider usable field of view and more image information available when digital magnification is applied.

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

The VISTA range is rated at ≤15mK, which is extremely sensitive for a handheld thermal monocular.

This becomes especially useful when natural thermal contrast is reduced, such as in damp, foggy, overcast or otherwise difficult weather conditions. Subtle temperature differences between an animal and its surroundings remain easier to distinguish.

Field of view determines how much of the landscape you can see through the monocular at one time.

A wider field of view makes scanning faster and helps you locate moving animals without constantly sweeping the monocular from side to side.

A narrower field of view usually accompanies greater base magnification, making distant heat sources appear larger but showing less surrounding terrain.

This is why the H35 tends to suit scanning while the H50 is more focused towards distance. The S50R is unusual because its much larger 1280×1024 sensor allows it to combine a 50mm objective with an exceptionally wide field of view.

Thermal detection range describes the distance at which a thermal imager can detect that a heat source is present under specified conditions.

It does not mean you will be able to positively identify an animal at the stated maximum detection distance.

Recognition and identification take place at shorter ranges and depend on target size, weather, atmospheric conditions, background temperature and the level of thermal contrast.

Detection range is therefore best used as a way of comparing the reach of different thermal systems rather than as a guaranteed identification distance.

One of the defining features of the NocPix VISTA range is its high-resolution 2560×2560 AMOLED display.

The unusually high display resolution complements the premium thermal sensors and helps present a detailed viewing image through the eyepiece.

The VISTA also uses a distinctive circular viewing system and large ocular arrangement intended to create a more natural and immersive viewing experience than a conventional small rectangular thermal display.

The 60Hz refresh rate across the range keeps movement smooth when scanning quickly or following moving wildlife.

The VISTA H35, H35R, H50, H50R and S50R use NocPix's removable IBP-7 rechargeable Li-ion battery system.

Two IBP-7 rechargeable battery packs are supplied with each VISTA monocular. This means a spare battery is included from the outset rather than needing to be purchased separately.

Each IBP-7 battery has a 4400mAh capacity and can be removed and exchanged in the field. This is particularly useful during longer sessions because a depleted battery can simply be replaced with the second supplied pack.

NocPix provides separate warranty periods for the main VISTA device, rechargeable battery and thermal detector.

For products purchased through a certified NocPix dealer or distributor, the warranty period begins from the purchase date shown on the invoice.

Please retain your Bamfords Online invoice as proof of purchase. If a qualifying warranty issue develops, contact Bamfords Online for assistance with the warranty process.

Which is the best NocPix VISTA?

The VISTA S50R is the flagship model and provides the highest thermal resolution in the range with its 1280×1024 detector. The best value depends on whether you need that level of image quality, an integrated LRF or a particular field of view.

Which VISTA has the widest field of view?

The VISTA S50R provides the widest field of view at 17.5° × 14°. Among the 640×512 H-series models, the H35 and H35R provide the wider 12.5° × 10° field of view.

Which VISTA is best for long-range observation?

The H50 and H50R are the long-range-focused H-series models thanks to their 50mm F0.9 objectives and 4× base magnification. The S50R offers premium long-range capability with significantly higher sensor resolution and a much wider field of view.

Which VISTA models have a laser rangefinder?

The H35R, H50R and S50R include integrated laser ranging. The H35 and H50 do not include an integrated LRF.

What does the R mean on NocPix VISTA models?

The R identifies a VISTA model fitted with an integrated laser rangefinder.

Is 1280×1024 noticeably better than 640×512?

Yes. A 1280×1024 detector contains roughly four times as many thermal pixels as a 640×512 detector. This gives the S50R substantially more image information and allows it to combine excellent detail with a very wide field of view.

How many batteries come with a NocPix VISTA?

VISTA models are supplied with 2 × NocPix IBP-7 rechargeable 4400mAh battery packs.

Can the VISTA batteries be changed in the field?

Yes. The IBP-7 packs are removable and interchangeable, allowing the second supplied battery to be fitted when required.

Do NocPix VISTA monoculars record video?

Yes. VISTA models support thermal image and video recording and include 64GB of internal storage, with microphone support for audio recording.

What warranty do NocPix VISTA thermal monoculars have?

NocPix specifies a 3-year warranty for the main device, a 2-year warranty for the rechargeable battery and a 10-year warranty for the thermal detector, subject to the manufacturer's warranty terms.
