PointShield™ is a Portable Diver Detection Sonar (PDDS) system for protection of vessels at anchor and ships at berth against underwater threats.

The PointShield™ is also suitable for fixed installations where limited area needs to be covered. Sites that may be secured using the PointShield™ include Nuclear Power Facilities, Underwater Pipelines and Cables, Naval Bases piers, Ports, Oil & Gas Terminals, Offshore Platforms and Canals.

The PointShield™ is lightweight, compact and portable to allow rapid deployment and retrieval. Nevertheless, the PointShield™ is robust and can withstand rough waters and long-term continuous underwater operation, making it ideal for permanent installations as well.

The PointShield™ PDDS supports fully automatic operation – from detection, through tracking to classification and alert – and thus eliminating the need for a well-trained sonar operator. Its advanced signal processing algorithms ensure the desired combination of very high Probability of Detection (PD) with very low False Alarm Rate (FAR).

The system supports detection of all types of underwater threats including Divers using Rebreathing Apparatus, Scuba Divers, and Unmanned Underwater Vehicles (UUVs). It provides Omni-Directional (360°) coverage, creating a security sphere that surrounds the protected object from all sides and covers the entire relevant water column.

The PointShield™ is in operational use by customers around the world and was successfully tested by navies, coast guards, energy companies and VIPs in both cold and warm waters.

The PointShield™ Portable Diver Detection Sonar (PDDS) is the only system that offers all of the following features:

  • Light and Portable – Small and light-weight, which enables rapid deployment and ease of movement between sites.
  • Detection of All types of threats:
diver detection sonar
diver detection sonar
underwater security
  • Fully automatic – detection, tracking, classification and alert are all done automatically by the system
  • High probability of detection (PD) – the system’s offers very high probability of detection for even the weakest of targets.
  • Low false alarm rate (FAR)
  • Real time and continuous monitoring for more than 1,000 sonar contacts simultaneously
  • Quick and Easy Deployment and Retrieval – the PointShield is easy to deploy and retrieve manually or using a special launch and recovery mechanism. The system is also suitable for permanent installations.
  • Modular design for optimal system coverage with the ability to combine multiple underwater units:
  • Proven in the water – Since 2007
  • Reliable and robust – 24/7/365 in all weather and water conditions
  • Best price/coverage ratio
  • Low cost of maintenance and ownership
  • User friendly HMI
  • Easy integration with other sensors and Command and Control (C&C) systems

The AquaShield™ DDS – high-performance Diver Detection Sonar offers the following detection ranges:

Detection of Open Circuit Diver (SCUBA) – 700 m
Detection of Closed Circuit Diver (re-breather) – 500 m
