Why do hunters sometimes fail to identify their target? A person doesn't look like a deer!

In spite of what many people assume, most hunting accidents aren’t the result of a bad attitude, over-excitement or inexperience. The shooter is usually a level-headed, long-time hunter who never thought it would happen to them. They 100% believed they were shooting an animal. Unconscious psychological factors strongly influence visual perception and can cause any hunter (no matter how safety conscious) to make a deadly mistake. Read more about this on the hunting accidents page.

Doesn't the IRIS System rely on ALL hunters using it?

Most hunters only hunt with people they know and trust, yet over two-thirds of hunting accident victims are shot by the person they’re hunting with. Even if you and your hunting buddy were the only ones in the world using IRIS, you’re already nearly 70% better off.

Shouldn't hunters rely on their own judgment rather than IRIS technology to identify the target?

Absolutely. No technology in the world can tell the difference between a human and an animal or say if it’s safe to shoot or not. That’s YOUR responsibility! IRIS comes into play after a mistake has already been made (i.e. after the hunter has decided he’s seen an animal and raised his gun to shoot it), but before he pulls the trigger. IRIS provides an additional degree of safety, but doesn’t replace common sense or the rules of safe hunting.

My rifle can shoot way further than the sensor can detect someone in IRIS gear.

Although modern hunting rifles can shoot thousands of yards/m, hunting accident data shows most accidents happen at well under 100 yards/metres. In fact, the average distance between shooter and victim is around 40 yards/metres. IRIS has been optimised to work best between 10 and 100 yards/metres, the range most hunting accidents happen at.

What happens if the battery dies or the sensor breaks down?

If the sensor isn’t working, it doesn’t suddenly make you unsafe, you just no-longer receive the added safety benefit. A dead battery can’t cause an accident, it simply means the sensor can’t help prevent one. You’re now no better or worse off than if you weren’t using IRIS at all.

What about hunter-orange, isn't that good enough to keep me safe?

While blaze orange can provide some degree of protection, it is not the perfect solution. Accident data shows about half of hunting accident victims are wearing blaze orange when shot.


Does IRIS work in the dark?

Yes. IRIS uses an infrared laser and can detect IRIS material day or night in all conditions.

Does IRIS work in the rain?

Yes. The sensor and IRIS patches are waterproof. Water drops on the lens or on the surface of the IRIS material won’t stop detection, but may reduce detection range.

Do I need to align or calibrate IRIS on my gun?

No. Thanks to the high-tolerance IRIS scope mounts no post-mounting calibration is required. Simply attach following the instructions, test, and you’re good to go.

Can the IRIS sensor see through vegetation?

Yes and No. The laser light cannot physically go through a leaf or branch, but because it spreads out in a cone of coverage, it can penetrate through all the small gaps between the vegetation. This means detection can often occur even when the target is quite obscured behind vegetation. But remember, it’s never safe to shoot at something you can’t clearly see and identify!

Can animals see the IRIS laser?

No. The IRIS laser is completely invisible to humans and animals. It uses a similar wavelength to many laser rangefinders.

Can any IRIS sensor detect any IRIS patch?


Will I get false alerts?

No. Nothing in the natural environment is reflective enough to trigger the alert. Anything that does will be man-made, and therefore not safe to shoot at anyway.

How long will the battery last?

Battery life is affected by many variables, including how often the IRIS sensor is switched on and off, how often the alert is activated, and the ambient temperature. Under normal conditions, a fresh battery will power the IRIS sensor for approximately 50 hours of continuous operation before the low battery state is activated.

The battery indicator light is the only indication the IRIS sensor is operating. It has two states: good-battery level and low-battery level.


  • A good-battery level is indicated by a single green flash.
  • A low-battery level is indicated by a double orange flash.
