DDIS-500 Diver Visual Sonar  900/2250kHz Visual Sonar  Autonomous Subsea Navigation  Large LCD Display  Low-Mag STANAG 2897 The DDIS-500 visual sonar is used to detect and identify underwater mines by clearance divers in poor visibility conditions and is certified to STANG 2897 for a low-magnetic signature. The DDIS-500 uses a multi-beam sonar, 900/2250kHz, to aid the diver in detecting and identifying mines. To support locating and marking subsea mines, the DDIS-500 uses an onboard navigation system that relies on internal sensors to provide navigation data. Information is displayed on a 12-inch LCD display. The unit also uses a low light video camera with adjustable LED light to capture images of subsea objects. All data is stored on a removable USB drive. Wet pluggable batteries provide up to 6 hours of operational use. DDIS-500 SPECIFICATIONS Imaging Sonar Blueview Dual Frequency Sonar Frequency 900/2250kHz Horizontal Field of View 45 deg Vertical Field of View 20 deg Range 100m @ 900kHz 20m @ 2250kHz The DDIS-500 is supported by mission planning & analysis software that operates on a Microsoft® Windows® based system. An operator can plan a dive mission, upload it to the USB drive, load the USB drive to the DDIS-500, complete the dive while recording the results, and analyze the data from the USB drive through the software.
