FS-3ER Navigation Sonar

The FS-3ER is FarSounder's flagship navigation sonar. It offers users 3D forward looking navigation information out to 1/2 nautical mile (900 meters) ahead of the vessel.

Extended Range Capabilities

FarSounder's latest navigation product offers the user the ability to select between a wide field-of-view or an extended range mode. The system can operate with a 90° field-of-view out to 1400' (440 meters) range, a 40° field-of-view out to 2900' (900 meters) range, or alternate with every ping between these two modes. 

System Components

The FS-3ER system includes:

• Rugged stainless steel Transducer Module with underwater wet matable connector
• Power Module in rack-mountable chassis
• Waterproof connection cable
• SonaSoft user interface software
• Marinized bridge computer

Transducer Elements

The Transducer Module's array face is curved in the horizontal and includes nearly 200 receivers and a separate transmitter. The array is encapsulated in a rugged urethane designed to provide years of protection to the transducer elements. Above and below the urethane are thin steel plates to provide added protection from debris and the anchor chain.

Installation

Typical installation of the FS-3ER includes integrating a Transducer Module fairing into the hull and mounting the Power Module inside the vessel. Check out our installation gallery for examples of installations on various hull types. FarSounder provides complimentary engineering support with advice on hull integration designs and drawing review services.
