The DT-NH7 is a multi-purpose dual-tube monocular built on the latest photoelectric technology: a high-performance Gen-2-enhanced image intensifier in a small, light body with distortion-free imaging. Objectives are swappable (3X/4X/5X) or extendable with 3X/5X afocal multipliers — the value class of the observation line.

How to Choose in This Family
- Field of view. 42° observation class (NH921/NH7/NH8XX/NH8XD) versus 50° head-mounted wide-field (DTS-31N/DTS-14).
- One unit or a system. Combinable members (NH8XX/NH8XD) cover both binocular and two-monocular duty with one purchase.
- Recording and thermal. Only the NH921 carries video output and the NH921T thermal-fusion upgrade path.
- Runtime. DTS-14 runs 80 h on low light — the long-shift pick.
Where this model sits: DT-NH7 is 400 g.

FAQ
Why choose the NH7 over the NH921?
The NH7 is the value class: engineering-polymer body, 400 g, 180-230 m observation — the NH921 adds full-metal housing, video output and the thermal-fusion path.
