Referee communication kit

The Avantalk FBIM is a Bluetooth 5.1 intercom built for football and handball referees who need reliable full-duplex talk over long range. It supports up to four users online at once and fits into a wrist bracelet for hands-free use during fast movement.

Battery life and weather resistance

An 850mAh cell gives up to 260 hours standby and 19 hours active talk after a 2.5 hour charge. The IP65 rating and -10 to 50 °C operating range let the unit work through rain, snow or extreme heat without extra protection.

Range limit for crew coordination

Maximum line-of-sight reach is 1500 metres between units, so crews spread wider than that will lose contact. Referees who need longer distance or integration with radio networks should look at dedicated radio systems instead.

Questions about this item

How do I mount the Avantalk FBIM intercom so it stays secure while I run?

Clip the unit onto the supplied wrist bracelet and tighten the strap; the headphone-style earpiece locks in place and will not shift during quick movements.

When will the 850 mAh battery need replacing and how do I charge it?

Recharge via the built-in port in 2.5 hours for up to 19 hours talk time or 260 hours standby; the sealed cell is not user-replaceable, so plan on a new unit when capacity fades.

What range limit appears first when four referees talk continuously at 1500 metres?

Bluetooth 5.1 drops out beyond 1500 metres line-of-sight; heavy rain, cold below -10 °C or obstacles will cut the usable distance sooner.
