ECHOLOGGER MRS900

One of the most compact mechanical scanning sonar systems in the market

Models

MRS900 (2,000m)

MRS900L (1,000m)

MRS900S (300m)

MRS900 is one of the most compact mechanical scanning sonar systems in the market weighing only from 380g (140g in water).
Its image quality with help of CHIRP technology outperforms its competitors. Its non-contact rotational mechanism for low noise frictionless scanning makes it possible to run years without breakdown.
It is optimally designed for Navigation of Underwater Vehicles (ROVs or AUVs).
