Installation of the sending unit
The sending unit must be installed in a turbulence-free zone in the hull. If
an echo sounder is installed, the Sumlog sending unit should be instal-
led at the same height and to the side of, or laterally offset to the echo-
sounder. Check for sufficient distance to stanchions, stringers,
bulkheads, etc. when drilling the hull.
Do not install the sending unit close to external valves, an-
odes, etc. to avoid influences by turbulence.
On sailing boats the sending unit should always be installed in front of
the keel, as close to the longitudinal ship axis as possible. On boats with
a long keel the installation should be at the end of the first third of the
hull, but not at the widest location of the hull.
On powerboats the sending unit should be installed at about the first
third of the hull and never towards the stern in a zone of strong turbu-
lence or up front, where strong disturbances by air induction must be
