Shot transmitter…With dynamite in the hole the guy in the recording truck looks at all galvos for noise and when all is quiet he sends a transmit signal to the shot hole setting off the dynamite and records the return signals from all the galvos until there is no longer a signal. He then declares all clear and work continues.
