Which two devices share the same WFOV and NFOV magnifications?

• A. DVO and TAS
• B. DVO and NVS
• C. NVS and LRF
• D. TAS and LRF

Answer: (B)

Understanding how field of view and magnification work helps here. WFOV gives you a broad look at the scene, while NFOV zooms in for detail. When two devices share the same WFOV and NFOV magnifications, switching between them doesn’t change how large targets appear or how the reticle aligns. That consistency is exactly what DVO (Day Vision Optic) and NVS (Night Vision Sight) are designed to provide—they’re built to use matching magnification steps so you can move from day to night without having to re-acquire targets or readjust sighting.

The other pairs don’t share those identical magnification specs, because their roles differ (for example, a laser range finder or a dedicated target acquisition system uses different optical paths and zoom levels). So the combination that maintains identical WFOV and NFOV magnifications is the Day Vision Optic and Night Vision Sight.
