Night vision is very old tech. Most night vision optics use analog image intensifier tubes — technology that existed ever since the 1930s. In fact, this is the same fundamental technology that the marines used in the Battle of Okinawa (1945). That said, technology has come a long way since then. And now, it’s gotten so good (and affordable) that it can even be used as an AR-10 scope
Which night vision device should you choose? By the end of this guide, you’ll find the right generation of night vision for you.
Let’s get started!
Gen 0 Night Vision
This generation is the ‘father’ of modern night vision. It is what soldiers used in World War II—basically, a big infrared searchlight to see in the dark. This huge searchlight was too heavy and impractical for common deployment. That’s why you can’t buy it. Instead, they developed…
Gen 1 Night Vision
In Vietnam, the military started using Gen 1 night vision optics. It was lighter, the light sensitivity was better, and it worked in very close-range applications. The result? It was the first usable night vision on the market. But is it the right night Gen for you? To find out, let’s break down its pros, cons, and how it looks:
- Very cheap
- Great for light usage
- Not very clear
- ‘Fish-eye’ lens effect
- Blooming or ‘halo effect’ around visible light sources
- Shorter lifespan (1,500 hours)
- Short distance—100 yards maximum range
- IR illuminator gives off position to others
If you’re just getting started or a hobbyist, then Gen 1 night vision is for you. It’s cheap and helps you see in the dark in very close-range applications (up to 50 yards).
That said, if you are a little more serious, then go for…
Gen 2 Night Vision
Gen 2 arrived in the late 70s. An added microchannel plate allows the night vision optic to be used without extra infrared illumination. This made Gen 2 night vision the first ‘lightweight’ tactical night vision solution. It changed nighttime warfare forever and it’ll probably change your nighttime hunts, too.
Let’s break it down:
- Affordable, quality night vision
- Doesn’t need an IR illuminator to work (although it has one)
- Improved image quality
- Longer lifespan (2,500 – 5000 hours)
- Lacks image clarity
- Medium range applications (up to 200 yards)
- Can cost as much as Gen 3
Either nighttime hunting or medium-range application (up to 200 yards) is best for Gen 2. It’s decent for the price. However, if you’re looking to step it up to the very best, then go for…
Gen 3 Night Vision
This is the latest Gen night vision on the market. It originally arrived in the 80s. For Gen 3, a gallium arsenide photocathode (or an upgraded tube) was added. As a result, you can now see almost everything in the dark. But is it worth the extra money?
To find out, let’s break it down:
- Highest quality night vision
- Great low-light performance
- Doesn’t need an IR illuminator
- Longest lifespan (10,000+ hours)
- Goes to 300 yards and beyond
- Can be used day or night
- Very expensive ($1,000+)
It’s best used for serious tactical and long-range applications (up to 300+ yards). To put it simply, Gen 3 is the very best, but it does cost a pretty penny. Sometimes going well above the $2,000 price range!
If Gen 2 or 3 are still too expensive for your budget but you don’t want to sacrifice quality or clarity, you’ll probably love…
Digital Night Vision
Digital utilizes the fundamental technology of night vision (photocathode tubes) and improves it by using modern silicon chips to display the image—similar to a digital camera.
An affordable optic that performs between Gen 1 to Gen 2 in night vision functionality, which is also completely safe to use during the day. Here’s the breakdown:
- Very affordable
- Can be used day or night without breaking the unit
- Reliable (as it doesn’t burn out easily)
- Can record video
- Not combat-tested yet
How It Looks:
Sightmark’s Wraith high-quality digital scope (MSRP $599.99) mixes expensive night vision tech and a magnified riflescope all in one. It is also affordable and reliable.
