Shark-S900S Single-Frequency Side Scan Sonar is a compact, lightweight, and portable sonar with ultra-low power consumption. It features 900kHz CHIRP signal processing technology, providing a range of 75 meters per side to ensure wide coverage. With a 0.2° horizontal beamwidth, it delivers high-resolution imaging.
The system’s core components include a pressure-resistant towfish, a high-strength Kevlar cable, a waterproof deck unit, and proprietary OTech sonar software. It features a robust and durable structure. To enhance underwater safety, we included an overload protection pin on the towfish that breaks upon impact. Its hydrodynamic design ensures steady towing, and an optional depressor fin enables it to reach greater depths. The system has an ultra-low power consumption design and supports both AC power supply and battery inverter power.
The proprietary OTech software includes features such as real-time image mosaicking, sonar image display, survey line planning and navigation, track tracking and coverage display, data recording and playback, target management and export, and multi-window sensor information display. The sonar image adaptive equalization technology ensures consistent display quality for both near and far images. With minimal parameter settings and a user-friendly interface, the software is easy to operate. It supports output in standard XTF format, enabling processing in third-party software.
FEATURES
• lightweight, one-man portable, user-friendly, and reliable
• Supports real-time switching between LFM Chirp signals and Continuous Wave pulses during operation
• Real-time map loading and mosaicking
• OTech’s multifunctional software offers free periodic upgrades and updates.
