MO: Module Only Generators


The 2 wire version of the CHP-MO-HP will begin transmission of a coded sequence as soon as power is applied, and alternatively a 3 wire version is available that allows separate transmit control.

AVAR: Autonomous Vehicle Acoustic Receiver

The AVAR may be operated as an independent unit for short term deployments using its on-board battery, or may be connected for long term power and real-time communications with an external controller.


Providing excellent customer service and offering state of the art Acoustic Tracking Equipment, we are “working together to make a difference in the world we share.”

  • All Sonotronics Fisheries transmitters are available with the new Open Protocol (OP) as approved by the European Tracking Network (ETN)

  • Existing Sonotronics Receivers may be retrofit to utilize this new telemetry standard
  • Look for a new long-life single frequency receiver, deep water rated, with removable media to quickly transfer collected data!

More information about the advantages of the new OP protocol may be found on the European Tracking Network website:
