Quick decision guide
- Wildlife observing: Night vision for detail (ears, antlers); thermal to spot hidden animals fast.
- Security/search: Thermal for detection through smoke/fog; pair with white/IR flashlight for ID.
- Navigation: Night vision keeps depth and terrain detail; thermal can mask obstacles.
Strengths and limits
- Night vision: Needs some light (moon/stars/IR); great detail; glass glare possible.
- Thermal: Reads heat contrast; works in low light and some obscurants; less facial detail.
- Legal: Check local rules for hunting/night use; some areas restrict IR/thermal.
Recommended pairings
- Observation + ID: Thermal monocular to locate; night vision binocular/monocular to identify.
- Home/land security: Thermal for initial scan; NV + IR illuminator for detail and recording.
- Search & rescue: Thermal for rapid sweeps; NV for terrain navigation.
