(MANSFIELD, TEXAS 2018/02/14) – New Sightmark Signal Digital Night Vision Monoculars are helping people see flawlessly at both day and night. With two different models, the 320RT 4.5×30 (SM18024) and 340RT 4.5×30 (SM18025), seeing in pure darkness (up to 380 yards away!) has never been easier.

Replacing the popular Ranger Digital Monocular series, the Signal lineup hits shelves packed with enhanced features. A new and improved high-sensitivity 640×480 CMOS sensor and high-resolution 640×480 LCD display ensure night time and low light performance. Both models feature available built-in video recording with sound, allowing users to take images and videos to show their friends or upload to the internet. The Signal can even stream directly to your smartphone or tablet for remote view via the Stream Vision app.
Why Choose a Digital Night Vision Monocular?
Digital night vision monoculars offer several advantages over traditional analog night vision. Unlike conventional systems that rely on light amplification tubes, digital models like the Sightmark Signal series use advanced sensors and LCD displays to create a clearer, crisper image in low-light and complete darkness. This allows for enhanced versatility—users can operate the device both during the day and at night without fear of damaging the unit from daylight exposure.
With a digital night vision monocular, you can:
- Capture and share: Record videos and take photos with sound to document hunts, wildlife encounters, or night-time surveillance activities.
- Use day or night: Eliminate the need for separate optics—digital night vision can handle both daylight and darkness with no issue.
- Zoom in closer: The Sightmark Signal features 2x digital zoom for up to 9x magnification, helping you get a closer look without moving.
- Stream remotely: Use the Stream Vision app to broadcast what you’re seeing straight to your phone or tablet—perfect for guiding a companion or keeping others in the loop.
Two Powerful Models—One Clear Choice
For ultimate stealth and discretion, the Signal 340RT’s 940nm IR illuminator produces no glow and is practically invisible to wildlife. This makes it an ideal choice for hunters, nature watchers, and security professionals who need to stay covert. On the other hand, the Signal 320RT offers an 850nm IR illuminator with slightly more visible light—but gains an extra 50 yards of nighttime detection range, making it perfect for users who prioritize long-range visibility.
Who Uses Digital Night Vision Monoculars?
Whether you're a hunter tracking feral hogs, a wildlife photographer capturing nocturnal animals, a property owner checking your perimeter, or just someone who wants to explore the night with confidence, a digital night vision monocular is an invaluable tool. Lightweight, versatile, and packed with technology, the Sightmark Signal helps you extend your vision beyond the limits of daylight.
