Products Description
DTS-31L,Built for Civilian Enthusiasts.
The DTS-31L is a high-performance night vision binocular designed specifically for civilian outdoor and tactical enthusiasts who want the iconic 31-style design without paying for specifications they may not actually need.
Exclusive 18mm Image Intensifier Configuration
What makes the DTS-31L different is not simply its appearance. It is the exclusive image intensifier configuration developed specifically for this civilian-oriented model.
We developed an exclusive 18mm image intensifier configuration with a FOM range of 1200–1400, specifically for the civilian market.
Built for Real Nighttime Use
DTS-31L combines a Gen 2+ image intensifier system with 1× magnification and a wide 50° field of view.
The wide field of view provides a more natural viewing experience and helps users maintain greater awareness of their surroundings during nighttime activities.
Why does this matter?
For many recreational and outdoor applications, users are looking for:
- The recognizable 31-style design
- Reliable low-light visibility
- A wide field of view
- Comfortable head-mounted operation
- Practical night vision performance
- A more accessible purchase price
- DTS-31L is designed around these priorities.
DTS-31L separates these two factors.
The housing maintains the familiar 31-style appearance while the internally customized tube configuration is optimized for civilian applications.
This makes DTS-31L particularly suitable for enthusiasts who want the look, handling characteristics, and night vision experience of a 31-style system, but do not necessarily require an ultra-high-FOM configuration.
