HMS-624 Side Scan Sonar
from Falmouth Scientific

The HMS-624 Side Scan Sonar (Fig.1.) allows the user to capture high resolution images of the sea bed in both shallow and deep waters. The data acquired can supplement bathymetric and magnetic surveys, as this system can be integrated with external sensors such as the G882 magnetometer,using the two serial input ports. The topside power unit is packaged with a 2U 19 inch rack mount which allows a 4Mb/s DSL and ethernet connection for the tow fish. The tow fish electronics within this sonar scanner use the Chirpciever 24-bit signal in addition to the 100/400KHz frequency in order to capture high resolution images at a maximum depth of 2000 meters.

The HMS-624 uses a flexible control interface which allows the CHIRP/CW modes pulse length, range and gain to be measured, whilst allowing the user to acquire and analyse the data using third party software such as OIC GeoDas, Chesapeake SonarWiz, Comm-Tech amongst others. Please be aware that the default software included in the HMS-624 price is the SwannPro software.

Additionally, FSI have designed a smaller, streamlined Dual Frequency HMS-624 Litt system (Fig.2.) for shallow depth prospection in marine environments. This system uses FSI’s Chirpciever 24bit signal and 100/400KHz operating signal to cover maximum depths of 1000 meters. The topside power unit uses an IP66 splashproof enclosure with a 4Mb/s DSL connection for the Tow Fish and the standard ethernet connection.
