Connection options: integral, offset and pigtail
The Sea Array 4 is a fully gimballed unit that maintains three mutually perpendicular geophones (one vertical, two horizontal) with full orientation in all axes, along with one hydrophone. It can be used with all major ocean bottom cable systems for 3-component and 4-component seismic data acquisition.
The fluid-filled unit maximizes damping and coupling. Multiple precision o-rings and full water-blocked wires and assembly assure integrity of the package at depths to 2,000 meters, but is limited to the operational depth of the hydrophone unit selected.
The slim line unit accommodates a choice of four field-proven geophones: the economical GS-20DX, the close tolerance GS-30CT, and GS032CT, or the X-Phone which provides the industry's tightest tolerances, lowest distortion and the highest spurious response in a single unit. Hydrophone selection from one meter to 2,000 meters.
