Hydrophone cables provide for the use of hydrophones (waterproof pressure sensors, natural freq. 10Hz) instead of traditional geophones, thus allowing the implementation of expedited seismic surveys in lakes, rivers, wells (downhole & crosshole), etc.
Since transverse waves are not transmitted in liquids, it will obviously be possible to detect only P waves (compression waves): for surveys in P&S wave wells, we recommend the 3D hole geophone Mod. GFA.
Hydrophone cables are available with fully customized length, number of hydrophones and spacing.
