How Does Airsoft Tracer Unit Work?

Tracer units are used to light up a BB as it travels through the air and adds a dramatic flair to any game. But what exactly is a tracer unit, and how does it work? Read on to find out.

What is an Airsoft tracer unit?

At its core, an airsoft tracer unit is essentially a device that emits light when it detects movement—in this case, the movement of an airsoft BB passing by. The most common type of tracer unit consists of two parts: a base-mounted illumination unit and an optical sensor.

The illumination unit houses two lights (usually green and red) that shine outward from the base, while the optical sensor is placed at the end of the barrel where it can detect the presence of a BB passing by.

When this happens, the optical sensor sends a signal to the illumination unit, which activates one or both lights, lighting up the BB as it travels downrange.

How do you use it?

Using an airsoft tracer unit is easy! All you need to do is attach it to your gun’s barrel (or rail system) and plug it into your gun’s battery (if applicable). Depending on your gun’s setup, you may need additional pieces, such as connectors or adapters, for everything to fit properly.

Once everything is connected, all left is to turn on your gun’s power switch and shoot! As long as BBs with fluorescent tips or glow-in-the-dark paint is applied, they will be illuminated as they fly through the night sky.

Are there any downsides?

The main downside of using an airsoft tracer unit is that it requires batteries. If your battery runs out during a game, your tracer will stop working until you change or plug in another battery source.

Additionally, some players find that their guns become harder to handle once they add extra weight from adding a tracer unit onto their guns. This can take some getting used to, but it should be fine for experienced players who are used to handling heavier guns.


Tracer units are great tools for adding drama and style points at any airsoft event! They also make it easier for teams to see where enemy fire is coming from since they can easily spot glowing BBs flying through the night sky. With proper setup and maintenance, these nifty gadgets can make any game even more exciting!

Whether you’re looking for something different or want something cool and flashy on your next game day, give an airsoft tracer unit a try – you won’t regret it!
