ABSTRACT:
A hydrophone with crossed pairs of geophones is provided with a strong light weight housing allowing use at several thousand feet deep in the ocean while still maintaining good sensitivity. The cruciform housing has a cylindrical portion conforming to each of the four geophones so that each cylindrical wall has small diameter and requires small thickness. The cylindrical portions are joined to a central body to complete the housing.
