Offset entry
This option is used to select whether the displayed water depth is from
the surface or below the Biducer.
• Set a 0 (zero) offset, to give the depth from the transducer to the
seabed.
• Set a negative offset, to give the depth from the keel to the seabed.
• Set a positive offset, to give the depth from the waterline to the
seabed.
1. At the OFFSET display, press depth and speed together
momentarily to enter edit mode.
