Trigger Tools

Sledge Hammer | Surface Source

The sledge hammer is used to generate seismic waves (P- or S-waves) at the surface. A piezotrigger element is attached to the hammer. The output piezo signal is transformed to a TTL pulse by a small box to provide an exact time break to the seismograph.

It is a suitable source for shallow downhole surveys up to a depth of 100 m.

Trigger Extension Cable

The trigger extension cable is a very robust cable which is spooled on a cable drum. The length can be specified according to customer requirements.
