The Start Microphone SM8 uses the sound generated by a start pistol to trigger an impulse for the start of multi competitor competitions.

The Start Microphone SM8 comes complete with a mounting bracket that can easily clamp to many start gun models.

A special Speech Amplifier SV4/SM8 is used to transmit the impulse back to the timer and a socket for a Headset Q34 allows constant communication.
