HS Code: 8512.30.30

Product Description

The Locator-D1 is a digital hydroacoustic locator device including a depth sensor. The electrical interface complies with the Water Linked D1 communication standard. The Locator performs a chain of advanced digital signal processing operations before transmitting an acoustic wave. The depth data is available through the D1 interface, and makes it well suited for retro-fitted and stand- alone applications. The locator can be configured with different cable lengths and connectors.

The Locator-D1 has the following features:

  • Integrated pressure/depth sensor
  • Omnidirectional directivity
  • Rugged polyurethane cable
  • RJ45 connector
  • 300m depth rating
  • 100m max cable length

The Locator-D1 requires the rest of the WaterLinked positioning system to be fully functional. That includes the Master-D1 and a set of Receiver-D1 units, all of which are included with the Water Linked Underwater GPS Development Kit.
