MRU5+ plus installed in a subsea bottle mounted on the top side of the EM2040 transducer casing. The EM2040 bow-mounted system on R/V Skidbladner is here shown in transport mode, hoisted up on deck. In 2015, the positioning system was changed to the Seapath 330+ including new GPS/GLONASS antennas shown in the photo below. The subsea bottle was also changed to a newer version. The antenna separation has been increased from 1.5 to 2 m.
