The FS-SPS underwater threat detection capability is designed to operate while the vessel is on anchor or at dock. However, should a threat be detected, one option available to FarSounder customers is to immediately make way. Unlike other products, the FS-SPS is not deployed via cables or hydraulic mounts. This means that a speedy departure can be used without risk to the equipment.
While underway, the system can be switched to forward looking sonar mode and used as a navigation sonar using the same hardware.
