New icListen Firmware Release: Enhanced Security and New Features

August 26, 2025

We’re thrilled to announce a new firmware update for Ocean Sonics’ icListen Hydrophones, bringing improvements that make your experience smoother, faster, and more secure.

This release includes important updates to several core libraries that manage access and communication with the hydrophone. These libraries now feature enhanced security layers that are faster and more reliable than ever, giving you confidence that your data is better protected.

In addition, we’ve introduced the zero memory option. This model prevents any recording or storage of data in the hydrophone’s internal memory. In other words, the device cannot record locally, ensuring that no data is written or retained onboard. This gives you complete assurance that all collected data remains under your control, with no possibility of unintended storage.

This update reflects our ongoing commitment to delivering cutting-edge, secure, and user-friendly solutions for underwater acoustics.
