Thermal Imaging Clip-On · Hunting · 35 mm
ThermTec HUNT 335 Pro – when your setup has to work outdoors, not just on paper.
It’s late in the hunting ground. The light is gone, the wind isn’t perfect, and now it doesn’t matter which number looks biggest in the brochure. What counts now is whether you can clearly see, whether the device mounts reproducibly on the scope, and whether you can operate it in the dark without fumbling with your setup.
The ThermTec HUNT 335 Pro is aimed at hunters looking for a compact thermal imaging clip-on with a 35 mm lens, 384 sensor, very fine thermal sensitivity, and interchangeable batteries. It’s especially suitable if your focus is on baiting, stand hunting, forest edges, and medium hunting distances.
Does the HUNT 335 Pro fit your hunting ground? →
384 × 288 solid sensor for typical hunting situations
≤ 15 mK fine thermal sensitivity according to ThermTec
35 mm F0.9 middle ground between range and field of view
399 g lightweight as a clip-on on your day scope
Our honest assessment
The HUNT 335 Pro isn’t a device for pure number lovers. It’s a compact clip-on for users who don’t want unnecessary front weight on their scope but still want more range and detail reserve than very small lenses offer.
The 384 sensor is solid but not top class. The 35 mm lens offers a sensible middle ground between range, detail recognition, and still usable field of view. It can work very well for baiting, stand hunting, and many field/forest edge situations. Those who regularly need to identify targets cleanly at longer distances or expect maximum image reserve should honestly also compare 640 devices.
Fits well if you …
are looking for a compact clip-on for typical hunting distances
mainly hunt at baiting sites, stands, forest edges, or medium field areas
want a lightweight setup and don’t want too much weight at the front of your scope
find a 35 mm lens a sensible compromise between field of view and range
are willing to carefully check mounting, adapters, and point of impact
Less suitable if you …
expect maximum detail recognition at longer distances
mainly want a pure observation device
need a particularly wide field of view for very dense forest situations
expect 640 image quality
don’t want to invest time in adapters, checks, and operating routine
Forest, field, baiting – the practical assessment
The 35 mm lens is one of the key points of this device. It offers more range reserve than smaller lenses but remains more compact and lightweight than many larger thermal imaging solutions.
For baiting and classic stand hunting, this is a sensible range. You get enough image reserve for many hunting situations without making your scope unnecessarily front-heavy.
The HUNT 335 Pro also works well at the forest edge, as long as you don’t constantly need to quickly scan large areas in very dense cover. In tight forest situations, a wider field of view can be more comfortable. The device is usable in open fields, but for regularly longer distances and fine detail recognition, stronger models with 640 sensors have the advantage.
Instructor and user tip
With clip-ons, it’s not just the device that matters.
The complete system of scope, adapter, mount, operating routine, and check is crucial.
Mounting Routine
Mark position of adapter and scope
Don’t unnecessarily loosen clamp repeatedly
Mount device straight and without tension
Consciously check locking, not on the side
Training Routine
Check point of impact after mounting change
Practice operation in the dark dry
Practice menu, standby, battery change, and remote control
Practically check usable scope magnification
Many problems with clip-on devices don’t come from bad technology but from bad routine. That’s exactly why a thermal clip-on device shouldn’t just be “slapped on,” but properly set up and regularly checked.
Comparison in Thermal Imaging Context
HUNT 335 Pro compact, 35 mm, 384 sensor, interchangeable battery less detail reserve than 640 devices baiting, stand hunting, medium distances
640 clip-on device more image reserve and detail recognition usually more expensive and depending on model bigger/heavier longer distances, more reserves
Thermal handheld device faster overview and comfortable observation not intended as clip-on device territory control, search, observation
Night vision device different image principle, often detailed with residual light/IR depends on light/IR and legal situation situational, not 1:1 comparable

Weight 399 g
Important: The manufacturer’s detection range is not a reliable engagement or shooting distance. “Recognising that something is there” is not the same as a clean hunting shot.
Scope of delivery According to the manufacturer, the HUNT 335 Pro includes the thermal clip-on device, Bluetooth remote control, USB cable, lens cloth, manual, charger, cotton swabs, and replaceable batteries. A suitable clamp adapter for your day scope must be separately checked to fit the scope.
Safety, Mounting and Care Check the correct adapter diameter, mount the device without tilting, keep clamp position reproducible, check point of impact after mounting change, protect optics from shocks, and observe legal requirements for hunting use in the respective federal state.
Frequently Asked Questions
Does the HUNT 335 Pro fit every scope? No. Adapter, connection thread, and outer diameter of your scope are decisive. ThermTec specifies M52 × 0.75 as connection thread. The suitable clamp adapter must be chosen separately.
Is the HUNT 335 Pro more for forest or field? It’s a middle ground. It’s interesting for baiting, stand hunting, and forest edge. In very dense forest, a wider field of view can be more comfortable. On wide fields, stronger devices with more sensor and image reserve have advantages.
What does the 384 sensor mean in practice? 384 × 288 is solid but not high-end. It’s enough for many standard hunting situations. Those expecting maximum detail recognition, longer distances, or more reserves in bad weather should compare 640 devices.
Do I have to zero or test fire the device? A clip-on device must be properly checked with your setup. After mounting, adapter change, or system changes, you should d
ie point of impact can be checked.
Is the specified detection range usable for hunting? No, not directly. Detection range does not mean reliable identification. For hunting decisions, it’s not just about seeing a heat source, but whether you can classify it safely and responsibly.
Does the device have a replaceable battery? Yes, ThermTec lists replaceable and rechargeable batteries with up to 7 hours runtime each for the HUNT 335 Pro. It’s important to distinguish this from the older HUNT 335 without Pro, where the data is different.

Our conclusion
We don’t sell you a thermal imaging device just because it has technical specs. For clip-on devices, the entire setup matters: device, scope, adapter, mount, operating routine, and hunting purpose.
If the HUNT 335 Pro fits your hunting grounds, it can be a compact and useful clip-on device. If you need more range, more detail reserve, or a different usage profile, we’ll tell you that just as clearly.
