| Common Questions |
|---|
| Is the thermal image 4K? |
No. The thermal sensor is 384 × 288; the separate digital sensor is 3840 × 2160. |
| Does it offer the same magnification in both channels? |
No. Thermal is 4–20×; digital is 5.5–22×. |
| Is 1,800 m the laser ranging distance? |
No. 1,800 m is the thermal detection specification; the laser rangefinder is specified for 10–1,000 m. |
| Does it need two batteries or four? |
Two are required for operation. The standard package contains four, providing a spare pair. |
| Can the batteries charge inside the binocular? |
Yes, using USB-C with the batteries installed; the supplied external charger is another option. |
| Can thermal and digital views be seen together? |
Yes. Picture-in-Picture can show a thermal main view with a digital inset, or a digital main view with a thermal inset. |
| Does shutterless mean manual correction is unavailable? |
No. HSIS is supported and manual FFC is still available when needed. |
| Can it display its view on a PC? |
Yes, through a UVC-compatible player using USB-C and Digital mode. |
| Can it continuously range while ballistic calculation is enabled? |
No. Use single measurements when ballistic calculation is enabled. |
