Pixfra Arc A604 PRO Thermal Imaging Monocular
£1,416.63 ex. VAT
Featuring a highly sensitive 640×512, 12μm, <18mK NETD thermal sensor paired with an ultra-wide 4mm f1.0 objective lens, the new Pixfra Arc A604 PRO delivers one of the widest fields of view of any thermal monocular on the market; presented on a crisp 1440×1080 OLED display.
The Arc A604 PRO comes packed with features to support serious observation work, including a built-in video recorder, six colour palettes, and screen sharing with up to four other people through the free Pixfra app.
A Wide Field of View, Built for Ecology Work
Where many thermal monoculars chase maximum range, the Arc A604 PRO takes the opposite approach. It's built around a 102° (H) / 83° (V) field of view - the widest currently available on any thermal monocular - so nothing about its design compromises that wide-angle performance for extra reach. In practice, that means you can scan and track fast, erratic activity across a broad area without losing your subject, which is exactly what bat surveying, bird watching, and wider wildlife and animal work demand. A 200m detection range and 20mm close focus distance keep it equally useful for examining detail up close - roosts, nest sites, tracks - as well as scanning the wider scene.
See More, However You're Working
The 640×512, 12μm sensor with <18mK NETD sensitivity gives genuinely fine thermal detail, whether you're a professional ecologist carrying out survey work, an estate manager keeping an eye on boundaries and woodland, or simply curious about what's on the land. Paired with 0.4x-3.2x digital zoom and a 0.41in 1440×1080 OLED display, the picture stays easy to read even when you're scanning a wide scene.
Runs as Long as Your Survey Does
A single rechargeable 3,200mAh 18650 battery gives up to 6 hours of runtime, and charges with a 5V USB-C connection - so it's easy to top up from a power bank between sessions or overnight ahead of an early start. Carry spare batteries for extending its runtime.
Share the View
Group observations are made easier through the free Pixfra app, which lets the Arc A604 PRO share its screen with up to four other smart devices nearby. So when one person picks something out, the rest of the group can see it too, without passing the device around. The app is free for both Android and iOS.
Comfortable in the Hand
At just 380g, the Arc A604 PRO won't weigh you down over a long observation session, and tucks easily into a pack or pocket when it's not in use. A magnesium alloy casing shrugs off the everyday knocks of fieldwork, while an IP67 rating means it can take a splash without issue. It's rated to keep working in temperatures from –30°C to +55°C, for the sessions that run later or colder than planned.
