I always identify the target, why do I need IRIS?

No-one thinks it will happen to them, until it does. Why risk it? It’s got nothing to do with whether you’re a good hunter or not, it’s simply acknowledging that the evidence shows accidents can happen to anyone, no matter how safe they think they are.

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

No. Even if you and your mate are the only ones in the world using IRIS, you’ll still be much better off, because 80% of accidents are caused by someone from the same hunting party.

Can IRIS identify the target?

NO! IRIS doesn’t know the difference between a deer and a person, and it can’t tell you what to aim your rifle at (that’s your responsibility!), but if you make a mistake and your rifle ends up aimed at your mate, then IRIS warns you about it.

My rifle can shoot way further than IRIS can detect

IRIS has been optimised to work best between 10-100 metres because that’s where 95% of hunting accidents happen.

What happens if the battery dies?

Nothing, just keep hunting but be aware that you’re no longer receiving the added safety benefit IRIS can provide. Plus IRIS gives a low battery warning anyway, so this is unlikely to happen.

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

It makes sense to wear clothing that contrasts with the environment, but accident data from the US shows about half of hunting accident victims are wearing blaze orange when shot, so it’s not fully protective.

Can I turn the sound off so it doesn't scare the game?

No. The audible alarm is a critical aspect of the alert. If you don’t want to scare them game, don’t point your gun at your mate! And anyway, although it’s very audible to user, the alert tone isn’t loud enough to carry far through the bush so it won’t scare the game.


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.
