As a long-time enthusiast of high-quality optics, I was fortunate to receive the Swarovski Optik TM 35+ thermal imaging monocular for testing. Swarovski Optik has long been synonymous with excellence in the field of optics, and I was eager to see how their entry into thermal imaging would perform, especially in the demanding conditions we often face in the UK.
First Impressions
Unboxing the TM 35+, I was immediately struck by its build quality. The device mirrors the design ethos of Swarovski's renowned EL Range binoculars and the Z8i rifle scope, both of which I have extensive experience with. The TM 35+ feels robust yet ergonomically designed, with a textured finish that provides a secure grip even in wet conditions—a frequent occurrence in our line of work.
The packaging included the thermal module, protective carrying case, lens covers, and essential documentation. The attention to detail is evident, from the smooth operation of the focus lens ( important for glasses wearing managers ) to the intuitive placement of buttons. It exudes the premium quality that we've come to expect from Swarovski.
Design and Modularity
One of the standout features of the TM 35+ is its modularity. It can function as a handheld thermal monocular or be attached to certain Swarovski rifle scopes (assuming others also) using the tMA thermal monocular adapter (sold separately). This dual functionality is particularly appealing for those who wish to streamline their equipment.
However, it's important to note compatibility considerations. In my case, attaching the TM 35+ to my trusty Blaser R93 equipped with a T8 moderator proved challenging. The size and configuration of the moderator interfered with the proper mounting of the thermal device. Additionally, the prospect of changing moderators and re-zeroing the rifle was impractical within my tight schedule. This highlights the necessity for potential users to ensure that their existing equipment is compatible or be prepared to make adjustments.
Performance in the Field
During testing, I primarily used the TM 35+ as a handheld monocular. In this capacity, it truly shines. The thermal imaging quality is exceptional. The device offers a crisp, high-contrast image that makes detecting and identifying heat signatures straightforward, even at considerable distances.
The TM 35+ features a 320x256 thermal sensor with a 12μm pixel pitch, providing detailed imaging. The refresh rate is smooth, minimising lag and making it easier to track moving animals. The device operates in several display modes, including white hot and black hot, which cater to different viewing preferences and environmental conditions.
User Experience
The TM 35+ is user-friendly, with a minimalistic interface that focuses on essential functions. For some, the simplicity is a significant advantage—there's less fiddling with settings and more focus on observation. However, I did find the lack of certain features somewhat limiting.
For instance, the absence of a "red hot" display mode was noticeable. In my experience, the red hot mode enhances the visibility of heat sources against cooler backgrounds, which can be particularly beneficial during dawn or dusk when temperature differentials are subtle. Including this mode would have added versatility to the device.
The TM 35+ does not offer built-in recording capabilities. While not a deal-breaker for me personally—as I seldom record footage during culling operations—it may be a consideration for content creators or those who document their activities for educational or management purposes.
Battery Life and Durability
The device boasts an impressive battery life. During my field tests, the TM 35+ consistently operated for extended periods without requiring a recharge. This reliability is crucial, especially during prolonged sessions in remote locations where access to power is limited.
Additionally, the TM 35+ remained cool to the touch throughout use. Overheating can be an issue with some thermal devices, affecting performance and comfort. Swarovski's engineering effectively mitigates this, contributing to the device's overall durability.
Regulatory Considerations
An essential aspect to address is the regulatory framework governing the use of thermal imaging equipment in the UK. Under current legislation, specifically the conditions outlined by Natural England for night shooting licences, the use of thermal imaging rifle sights is prohibited. Condition 17 on my licence explicitly states:
"For the avoidance of doubt, thermal imaging rifle sights are not permitted for use under a night shooting licence."
While the TM 35+, when used as a monocular, does not contravene this condition, attaching it to a rifle scope could be interpreted as using a thermal sight. This grey area necessitates caution. I would advise any professionals considering the TM 35+ for use in night-time operations to consult the latest regulations and possibly seek clarification from the relevant authorities to ensure compliance.
Applications in Deer Management
Given the regulatory constraints, where does the TM 35+ fit within deer management practices in the UK?
Daytime Stalking: The TM 35+ can be a valuable tool during daylight hours. Thermal imaging can detect animals obscured by foliage or terrain, increasing efficiency and success rates. However, traditional optics are often sufficient during the day, and the added benefit of thermal imaging may not justify the investment for all practitioners.
Scouting and Observation: The device excels in non-hunting applications such as population surveys, tracking movement patterns, and identifying hotspots of activity. This information is invaluable for strategic planning and implementing effective management programmes.
Training and Education: For educational purposes, demonstrating thermal imaging technology can enhance training sessions for new deer managers or conservation volunteers, providing insights into animal behaviour and detection techniques.
Comparison with Other Devices
In a market with increasing competition, particularly from brands offering thermal devices at lower price points, the TM 35+ positions itself firmly in the premium segment. Its build quality and imaging performance are superior, but whether these attributes justify the cost depends on individual needs and budgets.
Less expensive alternatives may offer additional features like recording or more display modes but may compromise on image clarity, durability, or customer support. Swarovski's reputation for excellence and service provides peace of mind for those investing in their products.
The Swarovski Optik TM 35+ is a high-quality thermal imaging monocular that delivers exceptional performance in a robust and elegantly designed package. Its simplicity and reliability make it a pleasure to use, and the imaging quality is among the best I've encountered.
However, potential users must consider equipment compatibility and regulatory limitations. Its utility may be somewhat restricted within the UK due to current laws governing night-time culling practices. For those primarily engaged in daytime operations or non-hunting applications, the TM 35 +offers significant advantages.
Swarovski has undoubtedly set a new standard in thermal imaging quality. While there are areas for improvement—such as adding more display modes or recording capabilities—the TM 35+ remains a formidable tool for professionals who demand the best.
Final Thoughts
The decision to incorporate the TM 35+ into your equipment arsenal should be based on a clear understanding of your operational needs and regulatory obligations. For those who value unparalleled quality and are looking for a reliable thermal imaging solution within the parameters of UK law, the TM 35+ is a worthy contender.
As technology and regulations evolve, I anticipate that devices like the TM 35+ will become increasingly integral to wildlife management and conservation efforts. Until then, it's an excellent example of precision engineering and optical excellence that we've come to expect from Swarovski Optik.
