River Bed Mapping High Accuracy Portable Echosounder

Application mode

Working station echoing mode:

Only need to connect the echosounder to the DGPS receiver and 12V DC battery can launch survey work, greatly simply water depth survey work.

Precise echoing mode:

Connecting to a surge compensator, for correcting error which evocable from surge in water depth surveying, to increase surveying precision.

Combined echoing mode:

The echosounder also carries out working mode with echosounder + laptop + GPS + battery, satisfying customer’s traditional surveying requirement.
Construction positioning surveying mode:

The echosounder is not only a set of digital echosounder, but also a set of stable industrial controlling computer. To effectively solve unstable AC power supply on board, it’s available for direct power supplying in 12V DC, connecting GPS receiver and processing construction.
