Type: Thermal monoculars Brand: Guide
The TD411 is a 384×288, 12 µm thermal monocular with a 19 mm F1.0 lens, giving 1.4x base magnification, a 13.6° field of view, digital zoom in 2x and 4x steps to 5.6x, and a stated 800 m detection range at 50 Hz. Sensitivity is quoted at 40 mK.
Its 640×400 OLED display is lower resolution than most rivals'. It has Wi-Fi to Guide's app; the retailer page does not state whether it records onboard, so that field is blank. Power is a removable 18650 cell rated at 10 hours, which is long for the size. Weight is 330 g at 150 mm. The page calls it splash-proof without an IP code.
The retailer lists it as no longer available, so it is clearance or used stock. At a low price it is a light, long-running 384 for woodland and farmyards; the small display and modest sensitivity are the compromises.
