Depth Sounder
Depth Sounders & Bathymetric Technology
Why Buy From Bench Mark?
Modern technology has opened up a world of possibilities for GNSS surveying equipment. Each new device promises ways to make your job easier — and they do! The CHCNAV D390 depth sounder is no exception. Offering a modern approach to small-scale hydrographic surveying, this device is essential to every surveyor’s toolbox. Depth sounders allow the modern surveyor to create bathymetric surveys of any body of water, accurately mapping the contours of the lake or seafloor. For an industry that once relied on lead weights and cord, bathymetry, or depth sounding, has come a long way with the introduction of modern depth sounders. They now use a sonar transducer to reflect sound waves off the seafloor, measuring the time it takes the sound pulse to reflect. These devices offer greater accuracy in mapping at a more affordable price.

Here at Bench Mark Equipment and Supplies, we always want to ensure that you get the right equipment that will not cost you too much money.

Yes. Bench Mark can ship equipment off overseas. However, if you are looking to purchase a set of batteries and nothing else, due to shipping restrictions we may not be able to send them to you. If you have any questions just let us know.
For most repairs, everything can be handled in house, and from the time we receive the unit you are looking at a 1-2 day repair time. The turn-around time is entirely dependent on whether or not the unit needs to be sent to the manufacturer for repair. However, if the unit needs to be sent away for repair to the manufacturer, the repair time can range anywhere from 1-2 weeks for larger repairs. If you need equipment and cannot afford to send anything away, Bench Mark may be able to provide you with a loaner or a discounted rental to keep you working.
Utilizing Depth Sounders in the USA
What You Need to Know About Bathymetry
Bathymetry is required in many waterways, both for construction and ensuring easy navigation. Used in conjunction with a GNSS RTK receiver providing accurate 3-dimensional positioning, an echo sounder like the CHCNAV D390 will generate a precise map of subsurface conditions. Whether you are trying to dredge a channel, locate pilings for a bridge, or map the contours of a lake, the CHC depth sounder is the perfect tool. Modern echo sounders are designed for easy integration with RTK GPS and other surveying equipment. The sounder outputs data strings which are input into various hydrographic software, including the HydroSurvey7 software, to build accurate 3D maps and contour models. This integration of technology allows a surveyor to enter a marketplace that was traditionally dominated by dedicated and expensive mapping sonar.
