The ARC Explorer Mk II is the newest generation of Marine Sonic Technology’s towed side scan sonar designed for search, survey, and recovery applications.  The Adaptive CHIRP technology provides the highest imaging quality possible from a side scan sonar and supports ranges up to 60% greater than non‐Adaptive CHIRP systems.  The high-resolution imaging and simultaneous dual frequency operation, with an adjustable tow point and variable transducer angle, make it an ideal tool for survey and infrastructure inspection applications that require a high level of flexibility.  The rugged construction and a 300 m depth rating all in a one‐man portable system also make it an ideal tool for the search, victim recovery, and security communities.

• A rugged stainless steel tow fish, portable watertight topside processor and a user choice of ruggedized laptop all interconnected with a twisted pair Kevlar tow cable make up the core of the ARC Explorer Mk II system.
• To best suit different user applications, two standard dual frequency options are available:
  • The 600 / 1200 kHz option provides the ideal compromise between long range and high resolution;
  • The 900 kHz / 1800 kHz option is optimized for applications that require ultra-high resolution imagery for detecting very small targets in the first survey pass reducing time and cost.
• Further, 150 kHz and 300 kHz low frequency transducer options are available for long range survey operations.

The small form factor of all system components as well as the weight-optimized design make the ARC Explorer Mk II ideal for one‐man operation on small vessels.  The 30 m and 100 m lightweight Kevlar tow cables included with the Explorer Mk II to provide flexibility for different applications and simplified cable management on those smaller platforms.  Customer‐specified lengths are also available.

Like all Marine Sonic Technology products, the ARC Explorer Mk II comes with the user‐friendly and self‐explanatory Sea Scan Survey acquisition and review software.
