Adapt these procedures as appropriate, to suit your individual
requirement.
CAUTION:
Where it is necessary to cut holes (e.g. for cable routing and

weakening critical parts of the vessel's structure. If in doubt, seek
the advice of a reputable boat builder.

Fitting transducers

Instructions for installing and maintaining the speed and depth
transducers are packed with them. Before attempting to install the
transducers, read these instructions and the Site requirements for
transducers described in this Chapter.
