Repetition accuracy

Pay close attention to the accuracy of your thermal imager, when mounting and dismounting the device. This requires a clamping adapter that must provide absolutely repeatable accuracy results, even when mounted under adverse conditions in the field. We recommend the two-part bayonet locking solution VENARI Duo connector for thermal imaging attachments!

Thermal imaging clip-on devices 2022 buyers guide

Last updated: 27.09.2022

Pulsar Krypton Test Erfahrungen Blogbeitrag

The latest thermal imaging attachments turn night into day. In just a few steps, your daylight optics become night vision-capable. On this overview page we have collected all current devices and further below we present the features of individual devices. When it comes to attachments, the focus is on repeatabe accuracy and ease of use. But also image performance is very important for successful use in the field.

Table of contets

What constitutes repeatable accuracy?

Point of impact deviations can occur with thermal imagers. It all depends on the correct mounting. There are good and bad solutions. In addition to the right attachment, it is important for the hunter to find the right mounting solution that leads to absolute repeatability in the field and under all conditions.

Thermal imaging clip-on devices - What to look for when buying?

Hunting ground & range – The hunting ground of the hunter has an impact on the choice of the appropriate thermal imaging device. Basically, the further my hunting distances, the more budget I have to plan for, as more powerful devices have more expensive components. If the hunting ground consists mainly of forest and paddocks, the hunter can get by with a less expensive device. If the proportion of field in the area is larger, or typical hunting distances are well over 100m, it is better to go for a higher-quality device. The price range of the devices currently ranges from 1,300 EUR for a Xeye CTP13 to around 4,500 EUR for current high-performance devices such as the InfiRay Mate MAH50 Series.
Repeatability of the attachment accuray – The term repeatable accuracy refers to two aspects of a thermal imaging attachment. Firstly, it is tested whether the attachment can deliver shot groups at 100m within a scatter radius of approx. 5cm. This then proves that the device itself is repeatable accurate – regardless of whether the device also shoots where the hunter is aiming. The repeatable accuracy in relation to a adjusted device (obligatory 5cm scattering circle) is significantly influenced by the connection of the attachment and the daylight optics. This means that a good adapter must be used so that the attachment not only shoots with repeating accuracy under optimal conditions on the shooting range, but also when quickly mounted on the pulpit. Therefore we distinguish: 
Repeatability of the attachment – the attachment can fire 3 shots in a 5cm scattering circle (regardless of whether it is adjusted to the daylight optics).
Repeatability of the adaptor system – the mounted attachment can be disassembled and reassembled without shifting the point of impact. Both of these factors together result in repeatable accuracy of the clip-on solution.
Adapter sockets – Until now, clamping adapters (Rusan, Smartclip) have often been used for mounting the attachment devices. These have proven their worth and ensure a firm fit. A disadvantage of this type of adapter is a possible shift in the point of impact when removing and reattaching the device – especially in confined spaces and in the dark. In these cases, an clamping adapter may be tilted or tightened crookedly. This often leads to point of impact deviations. We therefore recommend using a two-part adapter – VENARI Duo connector. The advantage is that the clamping sleeve remains on the lens and the bayonet ring on the attachment device. If one now wants to mount the attachment, it can only be locked in an exactly repeatable position within seconds. The hunter does not have to worry about the position of the screen or the exact alignment of the axes.
Battery life – Changing batteries in the pulpit in the dark is quite annoying. The battery life of the device is therefore an important aspect. Most devices use CR123A (short) or type 18650 (long) batteries, For some devices an extended battery housing can be ordered (Xeye CL42 and CH50w), so that the long 18650 batteries can also be used. Some devices (Nitehog) also use battery packs with extended battery life. Some manufacturers use proprietary battery systems (Pulsar) for quick battery replacement. In recent months quite a lot of companies changed to firmly mounted batteries, which are not interchangable. InfiRay Mate Series now uses firmly installed batteries, which can be extended by using external power banks.
Daylight optics magnification – The magnification of the daylight optics should not start too high for optimal use of an attachment. The problem with high magnifications is that the screen is zoomed in too much so that only part of the image is visible. Optimal lenses are those whose lowest magnification makes the entire screen of the attachment visible. We recommend a minimum magnification of 2 to 2.5x or less to see the entire screen. This value may vary depending on the unit. The magnification upwards is not an important criterion for the attachment – often it is not necessary to magnify more than 5 to 8x, otherwise the image becomes very coarse anyway. 
Daylight optics magnification – The magnification of the daylight optics should not start too high for optimal use of an attachment. The problem with high magnifications is that the screen gets zoomed on too much so that only part of the image is visible. Optimal lenses are those whose lowest magnification makes the entire screen of the attachment visible. We recommend a magnification starting at 2x to 2.5x or less to see the entire screen. This value may vary depending on your specific optics. The maximal magnification is not an important criterion for the attachment – often it is not necessary to magnify more than 5 to 8x, as the image gets too gritty at those high magnifications anyway.

New devices in the shop (October 2022)

New on the market from October 2022 is the “Mate” series from InfiRay Outdoor. The devices come with a new operating concept and the most modern sensor (<25mK sensitivity). The Mate is available with 25mm, 38mm and 50mm lens as well as with medium resolution (Mate MAL 25 & Mate MAL 38: 384×288 pixels) and high resolution detector (Mate MAH 50: 640×512 pixels).

Our current recommendations (October 2022)

Universal thermal imaging device: Best-seller for mixed hunting grounds and usual distances (application up to 150m), sufficient for most hunting situations: HIKmicro Thunder TH35pc (cheap) | Infiray Outdoor CL42 (price-performance also very good, advantage: several memory profiles for different glasses can be stored). You should also keep an eye on the MATE MAL25 & MAL38 devices in this segment, which offer more performance but are also a lot more expensive. 

TIP: The predecessor of the CH50w is the CH50 V2. The devices are almost identical. The difference between the CH50w and the CH50 V2 is the WLAN and recording function. If you don’t need this, you can go for the much cheaper CH50 V2 with a clear conscience.

Upper class / field areas / higher distances: Xeye CH50w (4 memory profiles, extremely high image performance, repeatable, high-resolution 12µm detector) or TQ50c. First impressions show that the just introduced MATE MAH50 is the future top dog in the upper class segment. If you want the highest performance, you can’t go past the Mate MAH50, although the price of this device is once again significantly higher than that of a CH50w / TQ50c.

Buying advice: Thermal imaging attachments presented

Infiray Outdoor CTP13 thermal imaging clip-on device

Xeye Iray CTP13 Wärmebild Vorsatzgerät
Preis: 1.089,00 

An entry-level device for stalking & short kirring distances – very affordable – especially light weight.

> Sensor 256×192 – 12 μm
> Extremely low weight: 130g (by far the lightest device on the market)
> Response up to approx. 55m
> Angle of view at 100m = 24m! (especially wide!)

Lightest thermal imaging device – The Infiray Outdoor CTP13 is the most affordable entry into the world of professional thermal imaging devices for hunting – and it is also a very special device. It is by far the lightest device we carry in our shop. Weighing only about 130g, it is significantly lighter – even than already light devices such as the CML25 from Infiray or the Nitehog VIPER. The CTP13 is therefore perfectly suited for movement hunting and is hardly noticeable on the rifle. There is no shift in the centre of gravity. In terms of performance and effective hunting range, the low weight naturally has to take its toll. With 256×192 pixels, the sensor of the small CTP13 has a lower resolution than the mid-range devices with usually 384×288 pixels. Due to the small lens diameter, the device has a field of view of around 24m at a distance of 100m – perfect for stalking to observe the approaching game early. The effective response distance is up to approx. 55m for a deer. The maximum detection distance of the detector is given by the manufacturer as 675m. 

HIKmicro Thunder TE19c thermal imaging clip-on device

Preis: 1.199,00 

An entry-level device for stalking & hunting up to 90m – very affordable – very comprehensive features.

> Sensor 256×192 – 12 μm
> Focusable lens
> Response up to approx. 90m
> Angle of view at 100m = 16.2m! (good midfield)
> WLAN with app (photo & video recording)


The TE19c from HIKmicro is the cheapest device in the THUNDER series and currently the cheapest thermal imaging attachment in our VENARI Shop. It is very similar to the mid-range Thunder TH35pc, but has a smaller lens and lower resolution sensor (19mm lens & 256x192px sensor). The system performance of the TE19c is thus in the entry-level class, but clearly above the CTP13. The advantage of the Thunder series is the good quality and equipment of the devices. Even the small TE19c comes with Wi-Fi, app support and a video recording function. With the VENARI battery extender, the Thunder can even take large 16650 batteries and thus has a continuous operating time of over 7 hours with one battery charge.

The TE19c is a very good device for short and medium distances. Response up to 100m depending on game and situation. Safe aiming is absolutely possible up to this distance. Very good: The device even has a focus lens and can thus be optimally adapted to the distance to the target in terms of image sharpness.

HIKmicro Thunder TH35pc thermal imaging clip-on device

Preis: 1.999,00 

A mid-range device for universal use (field, forest, mixed terrain) for carrying up to approx. 150m – best price/performance ratio with good features.

> Sensor 384x288px – 12 μm
> Response up to approx. 150m
> Angle of view at 100m = 13.12m! (midfield)
> WLAN with app (photo & video recording)

Best-selling universal attachment – The TH35pc from HIKmicro is the latest mid-range thermal imaging attachment in the HIKmicro Thunder series. It offers the same features as its sister models, including WLAN with app and recorder function, multiple colour palettes, hot spot tracking and picture-in-picture mode.

The TH35pc is the currently delivered variant. It differs from its predecessor (TH35c) in that the detector now has a better 12µm pixel interval instead of 17µm. The TH35pc is suitable for most hunting grounds, as a mid-range device it covers an optimal compromise between performance and price and can be used both in forest and field hunting grounds. We recommend the Thunder for distances up to 150m. The device can also be used at longer distances, but above 150m we generally recommend top-of-the-range devices.

Tip: VENARI Jagdtechnik has developed a rechargeable battery housing for the Thunder series, with the help of which high-capacity rechargeable batteries (type 16650) can be operated instead of the normal “small” CR123A batteries. The runtime is thus more than twice as long (over 7 hours) and guarantees undisturbed operation even during long shooting sessions. 

Infiray Outdoor CL42 V2 thermal imaging clip-on device

Preis: 2.279,00 

A mid-range device – universally applicable – very good picture – pleasantly light.

> Sensor 384 x 288 pixels – 17 μm pixel pitch.
> 42mm lens diameter
> Response from approx. 300m (deer)> Angle of view at 100m = 15.5m! (good midfield, absolutely sufficient!)
> Weight: 420g

Very good universal scope – Ready for any hunt – The Xeye CL42 from Infiray has already made a name for itself among hunters. It is one of our best-selling thermal imaging attachments and there is a reason for that. The image representation of the CL42 is very good. The hunter gets a very harmonious image with this device. We are convinced by the image both at close range and at a distance. The device has a two-stage zoom (2x / 4x) in manual mode. For this purpose, the CL42 is supplied with a screw-on eyepiece. VENARI delivers the CL42 with BONUS ACCESSORIES. NOTE: Xeye CH50 is the “big brother” of the CL42 – not its successor as is often mistakenly assumed. The CL42 and the CH50 are still produced in parallel.

HIKmicro Thunder TQ35c thermal imaging clip-on device

Preis: 2.589,00 

An upper class device for universal use, advantage of the very wide field of view (optimal also for forest areas) for carrying up to approx. 175m – extensive features

> Sensor 640x512px – 12 μm (high-resolution sensor, instead of the mid-range sensor of the TH35pc)
> Response up to approx. 150m
> Angle of view at 100m = 21.9m (very wide!)
> WLAN with app (photo & video recording)


Combination of the advantages of upper class and middle class – The TQ35c combines upper class and middle class. The device corresponds to the TH35pc, except for the sensor. The TQ35c has a higher resolution. So the device combines the sensor of the flagship model (TQ50c) with the lens of the mid-range model (TH35pc). The result is an attachment that is particularly versatile. On the one hand, the 35mm lens allows a particularly wide field of view (21.9m), which is even significantly wider than that of the TH35pc. This means that the device can also be used in the forest and at short range without any problems. On the other hand, thanks to the high-resolution sensor, it has enough power reserves even at longer distances in the field.

Tip: VENARI Jagdtechnik has developed a rechargeable battery housing for the Thunder series, with the help of which high-capacity rechargeable batteries (type 16650) can be operated instead of the normal “small” CR123A batteries. The runtime is thus more than twice as long (over 7 hours) and guarantees undisturbed operation even during long shooting sessions. 

HIKmicro Thunder TQ50c thermal imaging clip-on device

Preis: 2.798,00 

 A top-class device for field, forest and mixed hunting areas for use over 200m – very comprehensive equipment.

> Sensor 640x512px – 12 μm (high-resolution sensor, instead of the mid-range sensor of the TH35pc)
> Response up to approx. 150m
> Viewing angle at 100m = 15.4m (good mid-range, absolutely sufficient!)
> WLAN with app (photo & video recording)

Flagship model from HIKmicro – The TQ50c from HIKmicro is the top-of-the-range model in the Thunder series. It has a large 50mm lens and a high-resolution sensor (640x512px) with 12µm pixel interval. The equipment corresponds to the other devices in the Thunder series and is correspondingly extensive, including WLAN and app support. 

The TQ50c is aimed at hunters who need maximum performance at a distance and is particularly recommended for field hunting. Response is possible up to 200m, depending on the situation even further. We recommend this device for hunters who want to be able to aim beyond 150m.

Infiray Outdoor CH50w thermal imaging clip-on device

Preis: 3.389,00 

 A top-class device for field, forest and mixed hunting areas for use over 200m – very comprehensive equipment – now also with WLAN

> Sensor 640x512px – 12 μm
> Response up to approx. 150m
> Viewing angle at 100m = 15.4m (good midfield, absolutely sufficient!)
> WLAN with app (photo & video recording)

Flagship model from Infiray Outdoor (Xeye) – The CH50w is the top-of-the-range model from Infiray Outdoor. With its 50mm lens and high-resolution sensor, it is also suitable for long distances. In the current “w” version, the device now also has WLAN and app support as well as a video recording function. With the battery extender (included in the scope of delivery), the CH50w can also accept high-capacity batteries (type 16650) and thus significantly extend the continuous operating time. 

The CH50w is aimed at hunters who demand the highest performance from their thermal imaging attachment. The image performance and detail representation is the best currently available on the market. Advantage of the device in contrast to the competition: Up to 4 correction profiles can be stored and thus quickly changed between different lenses. 

Liemke Luchs-1 thermal imaging clip-on device

Preis: 3.289,00 

 An upper class device for universal use, advantage of the very wide field of view (optimal also for forest areas) for application even over 200m – extensive equipment

Sensor 640x512px – 12 μm 
> Response up to approx. 150m
> Angle of view at 100m = 22m (very wide!)
> WLAN with app (photo & video recording)

The Luchs-1 from Liemke is a modern attachment with a high-resolution sensor and 35mm lens. The image is also shown on a high-quality OLED display. On the equipment side, everything necessary is on board, including WLAN and app support with video recording. In the area of power supply, Liemke goes its own way with the Luchs-1. Unlike all the other devices listed, the Luchs-1 has a permanently installed battery with up to 9 hours of battery life – more than enough, even for a long hunt. 

Pulsar Krypton XG50 (FXG50) thermal imaging clip-on device

Pulsar Krypton XG50
Preis: 3.389,00 

The Krypton is available in two versions which can BOTH be used as attachments.

Krypton XG50 = attachment incl. eyepiece
Krypton FXG50 = attachment without eyepiece
In Germany, due to the legal situation, only the XG50 version is delivered (“Dual-Use”). 

The Krypton is an upper class device with a high resolution sensor (640x480px) and a large 50mm lens. As is typical for Pulsar, it has an extensive range of features. This includes WLAN with app support and a video recording function. A special feature of the Krypton is the proprietary exchangeable battery system. Unlike the other devices listed here, the Krypton can only be equipped with Pulsar’s own batteries. The good thing is that these plug-in batteries can be replaced quickly. 

Thermal imaging attachment or night vision attachment? 

If you read up on the subject of night vision for wild boar hunting, you will inevitably come across the subject of equipment and night vision devices. There are two different technologies for night vision devices

 

Residual light amplifier (classic night vision)

Thermal imaging devices

Properties of thermal imaging attachments

Although hunting requires a certain level of natural skill and reflexes – the right equipment is equally important.Day and night hunters alike rely on advanced technology to increase your chances of success. 

Any heat source instantly visible – The advantage of hunting assisted by a thermal imaging device is that no game remains hidden. Any heat source, no matter how small, is instantly visible even with a quick scan of the forest edge. Unlike IR-based night vision, the hunter also sees game that would not be visible to the naked eye – even in the best weather and during the day. 

Tandem of handheld thermal imager and attachment: eye relief – Another advantage of thermal imagers is their interaction with a monocular. Many hunters already use a thermal imager. If one adds a thermal imaging device to one’s equipment and not an IR-based device, the change from the observation device to the weapon with thermal imaging device is less stressful, as the display does not change (thermal image to thermal image). The situation is different when switching from handheld thermal imager to a night vision attachment (thermal image to night vision). The change in display and brightness means that the eye has to adjust briefly to this change. 

Night hunting is becoming increasingly popular. A thermal scope is used by hunters to maintain the detection range of the optic even in low light conditions. Thermal imaging attachments and thermal riflescopes use infrared sensors to detect the heat emitted by any thermal objects within range of your thermal imaging scope.

The thermal imaging scope now delivers thermal energy captured via infrared sensors as images back to the hunter’s eye.
Thermal imaging scopes and thermal imaging attachments are used for night hunting and, unlike night vision scopes or night vision attachments, can also be used during the day.

Thermal imaging attachments – i.e. clip-on thermal imaging devices – are usually mounted on your rifle*. They are placed directly in front of the daylight optics of your rifle. Thus, the magnification of your daylight optic is combined with the distinction of the thermal imaging signature in the field of view.

Depending on the quality of the screen of the attachment and the amount of zoom used, the images may be blurred. The manufacturers of the devices therefore give recommendations for the optimum zoom strengths.

Your riflescope is your optic by day. A traditional rifle scope increases the detection range in daylight – This is done by the lenses and light refraction within the scope. The thermal scope, on the other hand, is based on sensors and light detectors.
