Pulsar Telos Thermal Monocular

Manufacturer warranty information

The Pulsar Telos Thermal Monocular range has been engineered for professionals who require reliable detection capability through diverse environmental conditions. Designed for demanding fieldwork, Telos monoculars feature uncooled thermal sensors, IPX7 waterproof ratings, high-resolution AMOLED displays, and integrated video recording, making them ideal for nocturnal wildlife surveys or monitoring.

All Telos models are built around a modular design platform, allowing future upgrades of key components such as sensors, batteries, and lenses. These monoculars offer practical thermal solutions that extend beyond visual limitations imposed by darkness, fog, or vegetation cover.

Each unit includes a precision AMOLED display (1024 × 768), integrated memory, and compatibility with Pulsar’s Stream Vision 2 app for real-time transfer of data. Depending on the model, users can select devices with higher base magnification, enhanced NETD ratings, or built-in laser rangefinders for accurate distance estimation.

Compared to traditional binoculars and night vision optics, thermal monoculars in the Telos series enable non-invasive observation of wildlife in complete darkness and adverse conditions. They deliver superior performance for ecologists requiring consistent, high-quality thermal data in varied field scenarios.

Additional information

Units with higher thermal sensitivity (NETD < 15 mK) are especially beneficial in wet or humid environments where temperature gradients are minimal. Meanwhile, models with integrated rangefinders enhance the accuracy of spatial mapping and species movement tracking.

The Pulsar Telos Thermal Monocular range is broadly compliant with the key performance recommendations outlined in the Thermal Imaging: Bat Survey Guidelines (BCT, 2021). The guidelines advise a thermal resolution of 640 × 480 and a NETD of ≤50 mK (although resolutions as low as 320 x 256 can be useful in certain circumstances) - standards met or exceeded by all models in the Telos series, with the XP50 variant offering exceptional thermal sensitivity of <15 mK. The high-resolution AMOLED displays (1024 × 768), wide field of view, and up to 8.5-hour runtime support prolonged and accurate monitoring of bat activity in challenging field conditions. All models offer internal recording, enabling the documentation required for licence applications and reporting.

While the monocular format lacks the binocular comfort recommended for extended viewing, its lightweight, single-lens design improves manoeuvrability and ease of use during transects or hand-held tracking. The advanced thermal sensitivity in models like the XP50 also supports use in humid or low-contrast conditions where bat detection can be more difficult. Pipistrelle bats, due to their small body size and fast flight, are typically detectable with these units at distances of approximately 20–40 metres (at roost), depending on the sensor model and environmental context. Overall, the Telos range offers professional-grade tools that are well-suited to bat survey work when used in accordance with BCT guidance.
