Sparco GSM Car To Pit Intercom is a simple and cost effective way to communicate clearly from pit to car via this sim card driven GSM device. The unit is 12v powered (lead included) and is controlled by a simple on/off volume switch. It features a nexus male plug and can be adapted to suit most helmet headsets with either adaptor leads or female to female extension leads.

• Single volume control with on/off indicator
• Can be mounted to a dashboard or roll bar
• Military grade Nexus connectors

It also comes with an antenna with multi surface mounting. As long as there’s a mobile reception with the SIM provider in the area, it works in a similar way to a mobile phone.
