Profile: Teledyne Odom Hydrographic Systems, Inc. specializes in precision hydrographic echo sounders. Our product line includes single beam & multi beam echo sounders, velocimeters and transducers. Our hydrotrac portable echo sounder is a recorder, digitizer and transceiver. The unit is waterproof (with the lid closed), and easily transportable. It is simple to operate & employs a highly integrated digital and analog circuitry. The two 16-bit processors equipped inside the recorder share the real-time tasks of digitizing, printing, and interfacing, making the lightweight system an extremely capable instrument. Our SMBB200-9 single frequency transducer is usually mounted on an extension tube, but is adaptable to portable survey and navigation systems. It contains a transformer which can be used to match the impedance of the echo sounder, or allow the use of longer cables. The transducer is available in either a bronze or stainless steel housing.
