A portable, battery-powered hydrophone system designed for field recording of underwater sound. Optimized for uniform frequency response and wide bandwidth capture, making it well-suited for professional audio, industrial, or scientific workflows. Recordings retain full signal fidelity, enabling precise filtering, EQ, and analysis after capture.
From short-term monitoring to extended unattended recording, this system provides a practical, ready-to-deploy solution. Each configuration records directly to an SD card using a dedicated Zoom field recorder, with no external power or computer required.
How It’s Used
- Deploy the hydrophone at the desired depth, start the recorder, and capture to the SD card.
- After retrieval, recordings can be reviewed, processed, or analyzed using standard audio or scientific tools.
- For shorter deployments, the system can also be monitored live using headphones connected directly to the recorder.
- Can share sounds and record at the same time by using a 3.5mm patch cable and connecting the Zoom headphone jack to a powered speaker with AUX input.
- Recorders can also function as USB interfaces to a computer, phone, or tablet.
Important Considerations
- Recorders are not waterproof and should be handled with care or mounted in a suitable location.
- Battery life depends on recorder model and settings (sampling rate, phantom power, etc.)
- Cable length selection impacts deployment depth and surface noise isolation (longer cable allows deeper deployment away from surface noise, but is also more cumbersome to manage)
Applications
- Marine life monitoring and passive acoustic observation
- Environmental and habitat studies
- Scientific research and acoustic measurement
- Industrial monitoring and diagnostics
- Multi-channel recording and comparative analysis
