The InfiRay Jerry-31 offers an affordable entry into dual-tube white phosphor night vision, priced around $4,000. While it compromises on lens quality and features like auto-shutoff reliability compared to high-end US-made units, its dual tubes provide crucial depth perception for tasks like driving. It utilizes NNVT Gen 2+ tubes, which perform adequately but lack the gain of Gen 3, making it a viable budget alternative or backup.

Quick Summary

The InfiRay Jerry-31 is an affordable Chinese dual-tube white phosphor night vision binocular around $4,000. It uses NNVT Gen 2+ tubes and smaller lenses, offering less gain and more chromatic aberration than US Gen 3 units, but provides crucial depth perception.
