Key Features: H3-OCEAN-6000 Self-contained Hydrophone

Ultra-Long Autonomous Monitoring
Self-contained design with built-in high-capacity battery enables continuous underwater recording for over 1 month, and even supports up to 370 days of scheduled interval sampling for unattended deep-sea deployments.
High-Sensitivity Low-Noise Acoustic Detection
Optimized for capturing faint underwater sounds, featuring ultra-high sensitivity and low self-noise performance, making it ideal for marine mammal monitoring, seismic studies, and ambient noise research.
Wide Frequency & Flexible Sampling Options
Covers a broad frequency range (10 Hz–20 kHz) with multiple adjustable sampling rates, allowing users to tailor data collection to specific research or monitoring needs.
High-Resolution & Large Dynamic Range Recording
24-bit quantization paired with a wide dynamic range ensures clear, detailed capture of both faint and loud acoustic events without signal distortion.
Deep-Sea Ready & Compact Design
Rated for 6000 m depth, with a rugged, compact form factor that is easy to deploy and retrieve, suitable for moorings, seabed stations, and long-term ocean observatories.
Large On-Board Storage & Fast Data Access
Standard 512 GB storage (up to 1 TB optional) supports extended recording missions, with high-speed data download capability for efficient post-mission analysis.
Low Power Consumption for Extended Field Life
Ultra-low continuous power draw maximizes deployment duration, making it ideal for remote, long-term ocean monitoring projects.
High-Reliability for Marine Research & Applications
Built to withstand harsh deep-sea conditions, delivering stable and consistent acoustic data for marine biology, oceanography, environmental monitoring, and underwater noise studies.
