The Locator-S1 is digital hydroacoustic locator device including a depth sensor. The Locator does not require a tether integration for top-side communication. It only requires external power 10-18V to be provided from the underwater vehicle. Time-sync with the top-side is achieved using its internal GPS. That makes it perfect for integration with ROVs that don’t have an extra twisted pair in their tethers, such as a BlueROV2 with the Fathom Slim tether, or for fiber optic tethers.

The Locator-S1 has the following features:

  • Omnidirectional directivity
  • 300m depth rating


  • 1 x Locator-S1
