MOBILE HYDROGRAPHIC SURVEYING ECHO-SOUNDERS

Эхолот мобильный

Used for depth measuring and registration of the bottom profile under the moving vessel. The echo-sounders are installed on ships with the freeboard height of up to 1.2 m using the frontal device. The echo-sounders are used for hydrographic, surveying, scientific research, rescue and other works.

Measurement of the place depth is carried out according to the measured echo-sounding time while probing from device to the bottom, and back, and to the value of the water sound velocity introduced into the echo-sounder.

HYDROGRAPHIC SURVEYING ECHO-SOUNDERS FOR STATIONARY INSTALLATION

Used for depth measuring and registration of the bottom profile under the moving vessel. The echo-sounders are installed on any vessels in which it is possible to install hydroacoustic antennas embedded in the bottom of the vessel. The echo-sounders are used for hydrographic, surveying, scientific research, rescue and other works.

Measurement of the place depth is carried out according to the measured echo-sounding time while probing from device to the bottom and back, and to the value of the watersound velocity introduced into the echo-sounder.

MOBILE HYDROGRAPHIC ECHO-SOUNDERS WITH POSSIBILITY OF SIDE-SCANNING OF SURVEY LINE HAZARDS

Used for depth measuring and registration of the bottom profile under the moving vessel and for flooded objects detection away from the vessel. Suitable for mobile placement on hydrographic ships and boats.

Completed by the universal outboard hole. Allows to provide simultaneous measurements by single-beam echo-sounders to perform an overview of survey line hazards with the built-in side-scan sonar.

The echo-sounders are installed on ships with the freeboard height of up to 1.2 m.

The echo-sounders are used for hydrographic, surveying, scientific research, rescue and other works.
