PRECISION ICE FATHOMETER MГ-518М
Hydroacoustic equipment that permits to obtain on-the-fly and for sure the following information graphically presented on display screen:
• thickness of submerged part of ice;
• complete thickness of ice;
• echo-measured distance to open sea surface or to lower ice cover surface.
MAIN TECHNICAL DATA
