Currently, the only controlled active source available from EPIC is the PEG 40Kg Propelled Energy Generator, manufactured by R.T. Clark Companies, Inc. EPIC has purchased its first fully automated PEG-40Kg system in 2011. The system is light weight, and highly portable, and is designed to easily mount onto a truck or SUV hitch. Seismic energy is produced when  a large hammer mass weight is propelled by an elastomer band (i.e. a very large rubber band) onto an impact plate, producing an impact frequency range of 10-250Hz. The source is controlled with a hand held motor controller,  and can operate in single cycle or continuous cycle mode. The device is powered by a 12V large capacity battery (car battery).  The PEG-40Kg was received, assembled, and field-tested by  EPIC staff on June 23rd-28th, 2011.

GEODE 24-CHANNEL IN-FIELD SEISMOGRAPH.

System consists of one 24-channel Geodes, with two built-in high-speed connections to interface with other Geodes and a PC-compatible controller or the StrataVisor NZ seismograph.

Suitable for reflection, refraction, downhole, crosshole, surface wave, and tomography surveys, and seismic monitoring.

EPIC has been upgrading its pool of Multi-Channel Dataloggers in recent years to include multiple ES-3000 Geodes and a 60 Channel Strata View NZXP. These upgrades are also compatible with all of EPIC's Multi-Channel Cable System, which were originally purchased for use with the Geometrics StrataVisor NX. These  Units employ a new concept in portable exploration seismographs. They combine the ruggedness and high signal quality of a distributed system with the convenience and cost effectiveness of personal computer-based control devices. See Geode and Stratavisor Dataloggers for more Details.
