The HYD-2 is a hydrophone series used for marine seismic. Its stability, seal performance, omni direction, and sensitivity are well proven through field operations. It can work in water with the depth up to 100 m.

Main features:
• Nature frequency: 10Hz?5%
• DC impedance: 150O?5%
• Sensitivity: 12.6V/bar ?5%
• Maximum operation depth: 100 meters
