A complete bathymetry system includes a vessel, an echo-sounder (analogue or digital) and a positioning system (DGPS or RTK).

We are very happy that the new depth gauge allows us to explore until a depth of 120 metres.

On the far right side of the Seismic Lab, Hydrographer Jim Weedon was looking at several computer screens which monitor our single-beam bathymetry.

By means of a complex mechanism, this contraction, no more than a few tenths of a millimetre, moves the hand on the dial, and does so with unparalleled precision: less than 0.18% deviation for the depth gauge at 45 metres.

FUNCTIONS: Hours, minutes, small seconds, central hand for displaying dive depth up to 120 m, depth gauge subdial for displaying maximum depth, power-reserve indicator, date display
