The company is scan sonar/sub-bottom pro? ler systems. This is especially known worldwide for its high-quality products which include: useful where high resolution sub-bottom pro? ler data, that side scan sonars, sub-bottom pro? lers, bathymetry systems, requires the system to be towed near the seabed, is required.
