|The 3100 is EdgeTech’s portable version of their highly successful subbottom profiler product line. The system utilizes EdgeTech’s Full Spectrum CHIRP technology which provides higher resolution imagery of the sub-bottom structure and greater penetration. The 3100 is ideally suited for use in rivers, lakes, ponds and shallow water ocean applications up to 300m max depth. The system was designed for customers that require a portable system that can be used from smaller boats while not wanting to sacrifice image quality. Enserv's 3100 system comes with the SB-216S. The 216S operates at 2-16 kHz. Along with a towfish, the 3100 system comes with a portable splash-proof topside processor running EdgeTech’s DISCOVER software for display of the sonar data. The system comes standard with a 35m tow cable.
