Sentinel Intruder Detection Sonar (IDS) is the world’s most widely deployed Diver Detection sonar, developed to meet the underwater security requirements of private, commercial, government and naval end users.

The system reliably detects, tracks and classifies divers and small underwater vehicles approaching a protected asset from any direction and alerts security personnel to the potential threat. Whether it is protecting a critical infrastructure facility, offshore platform, sea port or super yacht at anchor, Sentinel’s autonomous monitoring capabilities, long range diver detection and proven low false alarm rates, provide a rapidly deployable, 360° underwater security solution for any application.
