Sea Scan ARC Explorer MK II
Professional Grade Complete Towed Side Scan Sonar System
The ARC Explorer Mk II is the newest generation of Marine Sonic’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, in conjunction with an adjustable tow point and variable transducer angle, make it ideal!

Description
The ARC Explorer MK II is 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 & 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 high range and high resolution, whereas 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. 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 of opportunity. The 30 m and 100 m lightweight Kevlar tow cables included with the Mk II provide flexibility for different applications and simplified cable management on those smaller platforms. Customer‐specified cable 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.
