Porpoise 84D

Single-channel subsea acoustic recorder with an external battery pack for longer deployments

Contact us

The Porpoise is a high-quality subsea acoustic recorder, ideal for monitoring marine mammals and noise pollution in real time.

Porpoise 84D has all the same features as a Porpoise except for the internal battery pack.

The internal 84 D-cell battery pack allows the user to go the distance with longer deployments of up to 1.5 years of continuous use at the highest sampling rate. Each unit includes 1TB of internal recording memory, and is user expandable with microSD cards to 8TB.

Key Features

  • Multiple selectable sample rates up to 384 kHz
  •  Real-time data streaming
  • 1TB of internal storage
  • 8 TB removable SD card memory storage

The Porpoise is very easy to configure and deploy, meeting the requirements for a variety of underwater acoustic measurement projects. Current applications for Porpoise include ambient noise monitoring and characterisation, construction monitoring and marine mammal research. Porpoise 84D can be deployed for 1.5 years (continual use) using internal power.

Real-time configuration, analysis and visualisation software (TRAC) is supplied with every Porpoise. TRAC allows users to easily set their instrument parameters including enabled channels, sampling rates, channel gain and recording schedules. With highly configurable sampling rates, intelligent on/off scheduling and configurable hydrophone settings, Porpoise is the smartest subsea acoustic recorder available.
