• 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.
