Impulsive joke

In shallow water, the accuracy of CM level can be achieved, and the deepening equipment with various frequencies and market pulse rates can meet most users. Despite the continuous development of new technology, single-wave back measurement is still retained, and this traditional instrument is still used for depth measurement in the world. The single beam depth has been developed from analog recording to digital recording, and its precision and accuracy have been greatly improved, which can meet the requirements of most sea frequency measurements.

Digital monitoring, motion attitude sensor, satellite positioning system (such as GPS system) and data acquisition software can greatly reduce the number of marine investigators and greatly improve the efficiency of marine investigation. Single beam test, the sounder will develop in the direction of high system integration, intelligence and miniaturization. Dual-band single beam test provides the possibility of measuring the air depth of the channel, as well as the potential function of the port and guides the measurement of large dredging area, which has practical significance.
