The Ocean Bottom Seismograph (OBS) system has been greatly slimmed down – this is ISOPOD. We make it as solid as possible, without any compromise on product quality or reliability. By using titanium and Syntactic foam, the system is very impact-resistant and can still operate at 6000 m under water. The ISOPOD is equipped with three 4.5 Hz geophones, and its internal data datalogger “6D6” can work continuously for 3 months.
