SENA SF2 DUAL is a Bluetooth communication system designed for helmets, supplied as a package for two users. It enables direct two-way communication between two workers at distances of up to 800 meters in open terrain.

Thanks to Full-Duplex technology, both users can speak simultaneously without interruption. This is essential when working at height, in arboriculture, during structural installations or service interventions, where continuous team coordination is required.

The device can be connected to a mobile phone for making and receiving calls, streaming music or listening to navigation instructions. The Audio Overlay function allows simultaneous use of the intercom and audio transmission.

Voice control (VOX) is supported, so hands remain free for work. Up to two mobile phones can be connected simultaneously.

The digital processor suppresses ambient noise and reduces echo, ensuring high communication clarity even in noisy working environments.

The headset is robust, weather-resistant and suitable for professional use. It can also be used while charging.
