ION has been providing the industry with precision geophones since 1967. Our line of geophones and ancillary equipment capture high-quality data and operate efficiently in any seismic data acquisition environment and climate. Our SM-24 rotating coil geophone is the industry leader with an installed base of over 18 million elements. Manufactured under the coveted ISO 9001:2008 certification, our geophones are unsurpassed in their quality and are now more competitively priced than ever.

A Complete Line of Geophones & Equipment

  • SM-24 – Provides high-fidelity data in 2D and 3D seismic surveys
  • LF-24 – Low-frequency geophone for vibration monitoring, low-frequency seismic measurement, blast monitoring, vibration measurement of buildings, and site engineering

Our geophones are complemented and supported by a complete line of ancillary equipment including:


  • SMT-400 – Fifth-generation tester that once again sets the industry standard for geophone and string testing
  • SMT-40 – Hand-held unit that efficiently checks geophone string resistance, impedance, and polarity

Cables & Connectors

  • Cables – Available in a variety of configurations, length, and weight
  • Connectors – Available for use in every conceivable environment: desert, marsh, transition zone, arctic


  • Land – Water-tight and designed to withstand the harshest environments
  • Arctic - Arctic-proven, machined aluminum case for use in cold weather applications
  • Marsh - Suited to any situation where the seismic line encounters water
  • 3-component - Ideal for gathering multi-axis data in a wide variety of environmental and surface conditions
