2.4 Installing the Depth and Speed Transducers
If you are installing your RayData as a stand-alone unit, you need to
install the depth transducer and the speed transducer (incorporating the
temperature transducer) that will be connected to the RayData.
The depth and speed transducers are normally supplied with detailed
installation and maintenance instructions. You must read these
instructions, together with the information in this chapter, before
attempting to install the transducers.
Transducer Type
The RayData is supplied in various configurations. Depending on your
choice, one of the following transducer sets is included:
• Plastic through hull depth and speed transducers, suitable for use with
Glass Reinforced Plastic (GRP), Steel and Aluminium hulls (with

Caution: Plastic through hull transducers must not be used on
vessels with wooden hulls.
• Bronze through hull depth and speed transducers, suitable for use
with fibreglass and wooden hull installations (with system M78709).
• Combined depth and speed bronze triducer (with system M78710).
The following transducers are also available as options:
• Retractable bronze depth transducer (part number M78717)
