Single Frequency Water Depth Echo Sounder

What is Echosounder?

Echo sounding is a type of SONAR used to determine the depth of water by transmitting sound pulses into water. The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with the speed of sound in water at the time. This information is then typically used for navigation purposes or in order to obtain depths for charting purposes. Echo sounding can also refer to hydroacoustic "echo sounders" defined as active sound in water (sonar) used to study fish. Hydroacoustic assessments have traditionally employed mobile surveys from boats to evaluate fish biomass and spatial distributions. Conversely, fixed-location techniques use stationary transducers to monitor passing fish.

The word sounding is used for all types of depth measurements, including those that don't use sound, and is unrelated in origin to the word sound in the sense of noise or tones. Echo sounding is a more rapid method of measuring depth than the previous technique of lowering a sounding line until it touched bottom.

Features of the Echo Sounder:

• With advanced frequency conversion technology, HD-370 can reduce noise caused by transducer and enhanced echo intensity. In addition, the HD-370 supports different frequency transducers to meet the demands of different hydrographic projects.

• The optimal TVG curve of HD-370 is designed according to the transmission properties of sonar in water which can greatly optimize sounding performance and solve the issue of shoal water sounding.

• Portable design, high-definition LCD screens and mass storage make field operations much more convenient.

• Preinstalled Hi-Sounder software reduces your software cost.

• With the low frequency sounding function, HD-370 can easily get mud thickness data.
