How audio guidance lets a blind athlete aim

The first question most people ask about vision impaired shooting is mechanical: if you cannot see the target, how do you point a rifle at it? The answer is not a camera and a screen. It is sound, and the way the sound changes tells you which way to move.

The signal

World Shooting Para Sport describes the discipline this way: athletes use air rifles to fire a series of shots at a stationary target, and they use an audio signal to guide their aiming, with the audio signal rising in pitch as the point of aim moves nearer to the centre of the target.

That single sentence contains the whole interaction, and it is worth reading slowly. Pitch is the guidance. Higher means closer to the centre. Lower means further away. As the federation describes it, the cue is pitch (we found no mention of spoken or left/right instructions on that page): the athlete searches for the direction that raises the pitch, and the highest pitch they can hold is the point they fire from (our reading of the federation’s description).

This also explains why the class is a genuine skill rather than a technicality. Holding a rifle steady while listening for the highest pitch, and firing at the moment you are there, requires the same stillness and timing that sighted shooters use — with an extra information channel that must be learned. The federation’s own framing of the sport applies: the ability to steady hand and mind to deliver a sequence of shots requires well-developed concentration and emotional control.

How the system knows where the rifle is pointing

The federation’s technical specification for vision impaired competition (VI Technical Specifications, file dated 01-2026) requires an infrared LED mounted 60 mm directly below the centre of the rifle target, with a green LED above it so the jury can see that it is working. Universal infrared units are described for SIUS, Megalink and Meyton electronic targets. The specification does not, in the text we read, explain how the aiming device turns that signal into pitch.

Approved equipment, correctly described

The federation’s vision impaired page names two approved suppliers: the VIS 500 audio aiming device from EcoAims, and VIASS Pro from VIASS. Their inclusion here is information, not an endorsement.

That is the complete relevance of those names to this site. They appear because an official document lists them as approved for competitions, and a reader checking an equipment list needs to know that. Nothing on this page recommends buying either system. If you are entering a competition, the competition’s own approved-equipment list decides what you may use.

What the athlete actually does with it

A sequence of shots, not a single one. The event structure is 10m rifle, which places this discipline within the SH-VI sport class described by the federation as allocated to athletes with a vision impairment for competition in 10m rifle events. Because the target is stationary and the athlete is searching for a pitch, the loop is: settle, listen, adjust, find the highest pitch you can hold, fire, repeat (our reading of the federation’s description).

That is a loop an athlete can practise, and it is also a loop a coach can observe from the outside. Nobody needs to see inside the athlete’s head to know whether the pitch they settled on was the best available.

What this page does not cover

Not the talent pathway, not the cost, not the legalities of air rifles in a given country, and not the medical eligibility criteria for the SH-VI class. Those are separate questions with separate sources, and this page deliberately stays on the mechanism.
