Aquacom® Combox – One diver air intercom (2 wire only).

The Aquacom® ComBox is a compact, self-contained one diver air intercom. It allows clear two-wire communications using a powerful 20-watt amplifier and a powerful front panel speaker, ”Silver Bullet”.

The ComBox is rugged and offers many features others dream about. The Push-to-Talk (PTT) control is an industrial grade switch designed to be pushed all day long. The front panel speaker is small but packs a lot of sound. In hi-noise environments or where privacy is a concern, the optional deluxe headset is available. In all, the ComBox is the finest one diver box on the market.
