The Pixfra Arc Series of thermal imaging monoculars have long stood as ground-breaking devices, especially for those focused on bat surveying, ecology, and wildlife monitoring.
Now, taking wide-angle observation to the next level, the new Pixfra Arc A613 Pro arrives to replace its predecessor with improved thermal sensitivity, enhanced range, and crisp new display technology.
The Pixfra Arc Pro Series consists of high-performance thermal imaging monoculars designed around what wildlife observers need most: image quality, video recording, and a broad field of view. If you are looking for the ultimate tool for close-to-mid-range environmental monitoring, look no further than the Pixfra Arc A613 Pro.
Why choose the A613 Pro?
The Pixfra Arc A613 Pro takes the compact, cost-effective formula of the original Arc A613 and sharpens its core performance. Featuring a highly sensitive 640x512, 12µm sensor with an upgraded <18mK NETD rating, it picks out the faintest heat signatures in cold or low-contrast environments. Paired with a fast 13mm f1.0 objective lens, it renders sharp, vibrant thermal images onto a high-resolution 1440×1080 OLED display.
Where many thermal monoculars chase magnification at the expense of vision, the A613 Pro preserves the generous 32.3° (H) x 25.8° (V) field of view that made the original A613 a favourite among ecologists. This wide view allows you to catch movement at the edge of the frame and track fast, unpredictable activity—such as bat roost emergences or bird flights across open areas—without losing subjects in a narrow tunnel of view.
It doesn’t stop there. The A613 Pro boosts maximum detection range up to 700m and features an extended power system powered by replaceable 18650 Li-ion batteries delivering up to 6 hours of runtime per battery (with two batteries supplied in the box so you can swap and keep going all night).
When it comes to capturing field footage, all Arc models include 32GB of built-in storage with support for continuous video recording up to 2 hours per clip, making it simple to record entire survey sessions for post-fieldwork review.
Designed for group survey work, the Arc A613 Pro connects to up to four smart devices simultaneously via the free Pixfra app (up to 20m away). When one team member spots an animal or roosting bat of interest, the entire group can watch live on their own screens without having to pass the monocular around.
Built for rugged field conditions, the lightweight magnesium alloy body weighs just 370g, features an IP67 waterproof rating, and is rated to perform in temperatures ranging from –30°C to +55°C.
How the A613 Pro Improves Field Surveys
The Pixfra Arc A613 Pro isn't just an observation tool — it's engineered to directly solve common field survey challenges. Its broad 32.3° field of view ensures you never miss fast, peripheral movement across tree lines or building eaves, while the built-in tripod mount allows for static, hands-free monitoring so you can safely record notes or manage secondary gear. Add in swappable 6-hour batteries, continuous video recording, and multi-device app streaming, and the A613 Pro delivers an unmatched balance of survey accuracy and efficiency.
