This versatile sub-bottom profiling system operates at 100, 200 and 400 Joules. The boomer transducer can be towed behind the vessel on a catamaran, or deployed on an "over the side" mount attached to the vessel rail. We have had excellent results from these units for decades around the world. The sparker electrode option provides lower frequency content and higher power for deeper penetration into marine sediments.

 

 

This profiling system typically shows seismic penetrations of tens of metres (dependant on the local geology). It is compact and suitable for small vessel operations.  It can be operated from a quality 2 kVA AC generator. The recieve hydrophone array is a 4.5 metre, 10 element array with an integral preamp.  Further signal conditioning is achieved with Khrone - Hite bandpass filters / amplifiers.  Finally, Data acquisition and recording can be acheived with a variety of software sets:  DR GEO, SONAR WIZ, CODA or HYPAK.
