VDO Logic Log Depth Montageanleitung Und Bedienungsanleitung Seite 91

INSTALLATION
On sailboats the senders should always be installed ahead of the keel,
as close to the longitudinal ship axis as possible. In the case of a long
keel the sender location should be in the first third of the hull, but not clo-
se to the maximum keel thickness.
Especially on sailboats it is important to install the sender vertically,
otherwise - due to additional list - a depth measurement may become
impossible.

Echo sounder sender
On motor boats the recommended installation is at about two thirds of
the hull length, never at the stern, in the zone of strong turbulence, or
near the bow, where disturbances due to strong air suction is to be ex-
pected.
An ideal location is near the longitudinal ship axis in the area of the first
stringer, if possible directly ahead of the engine compartment, This is the
only location where the echosounder can function without disturbances,
even at high speeds.
The deviation from vertical installation should not exceed 10 degrees,
but at high speed, tight turns and deep water this may cause failures of
the measurement.
