Source Signature Recorder
Provides Zero Time, Location and Source Quality Control
 

A General Source QC Tool:

GPS accuracy for time break collection and source equipment locations.

32-bit, high speed, ADC chip for lower noise and increased accuracy for signatures.

Operates independently of crew, including observer and shooter or operators.

Can be used with any Vibrator Control System.

Great for monitoring rental equipment and operators.

Provides accurate start times that can be used with any nodal recording system.
