The company reports that SHADOWS is the first commercially available off-the-shelf (COTS) Synthetic Aperture Sonar (SAS), is a quick and efficient high-performance sonar system with synthetic aperture processing, which is designed to offer unparalleled image quality in real-time with no gap at nadir boosting productivity. According to IXSEA, SHADOWS doubles the resolution while reducing survey costs by one- third. It is positioned as the solution for all sidescan survey applications: cable route, offshore mining, pre-dredging survey, small objects search on the seabed and shipwreck search and salvage. Moreover SHADOWS is compatible with GAPS and POSIDONIA, IXSEA's USBL positioning systems. Visit www.maritimeequipment.com/mt & Click No. 17 digital towfish, either 325/100kHz or 780/325kHz. Visit www.maritimeequipment.com/mt & Click No. 16 EdgeTech Side Scan System Options EdgeTech will introduce a new dual simultaneous 300/600 kHz option for its existing 4200-FS Dual Mode Side Scan System. The current 4200- FS System operates dual simultaneous 120/410 kHz frequencies. The new high frequency option aims to pro- vide the user with superior imagery at ranges of at least 230 m/side on the low frequency and 100 m/side on the high frequency. In High Definition Mode (HDM) the system operates conventional dual simultaneous 300/600 kHz frequencies. In High Speed Mode (HSM) the system oper- ates in MultiPulse mode on either selected frequency at speeds of up to 10 knots while meeting IHO and NOAA specifications for surveys.
