SIG has developped its own hydrophone elements to mount into the streamers, and make high resolution arrays to work with sparker and boomer systems.
The SIG 16 hydrophone streamers have small diameters of 31 mm, with a density of 1.05 on standard. The poluyrethane tubing keeps the section flexible over the years.
The configuration of the hydrophone arrays are customized, according to the needs of the geophysicists.
