Main features

The integration of high performance super land geophone and hydrophone is realized.

It is filled with liquid damping oil, which has reasonable damping and anti-interference performance and good coupling characteristics.

The whole injection molding process completely solves the hidden danger of leakage of water and electricity.


PS-10GS (equivalent to SG-10) or PS-10ES (equivalent to SM24) land detectors or VAS-90 land detectors with higher sensitivity can be selected in the land detection part, and SF-25 (equivalent to MP-25) series hydrophones can be used in the water detection part
