About Us
Teledyne Geophysical Instruments has earned a strong reputation in the industry for delivering high-quality marine seismic exploration products. Our products are used aboard more than one-third of all commercial seismic research vessels.
The Teledyne name in the geophysical industry dates back to the 1960s, when some of our earliest designs for streamer cables, energy sources, and recording systems were put to use aboard seismic research vessels around the world.
