10.4.7 Types and range of sondes
Standard sonde
The standard sonde combines compact size with
a strong signal and is the standard sonde for most
applications unless a smaller size, greater depth or
rugged construction sonde is required.
Figure 10.9: Standard sonde
Super small sonde
This is a specialized sonde particularly suitable for no-dig
applications. This type of sonde has an interchangeable
battery compartment so that the length of the sonde can
be altered. Shortening the length of the sonde means that
fewer batteries can be accommodated and this will affect
battery life.

sondes
Sewer sonde
This sonde incorporates a very strong housing and makes
the sonde suitable for use in municipal sewer systems.
The sonde has a long life for daily use in all conditions.

FlexiTrace
The FlexiTrace is a traceable plastic covered fiberglass
rod incorporating wire conductors and is used for locating
small diameter, non-metallic pipes to a depth of to 3
meters. The FlexiTrace can be inserted into a pipe or
duct as small as 12 mm/0.5 inch internal diameter with
a minimum bend radius of 250mm. Batteries are not
required, as the FlexiTrace is powered by the RD8000
transmitter.
The FlexiTrace can be used in two modes: Sonde mode
or Line mode. In sonde mode only the tip of the FlexiTrace
is energized whilst in line mode its whole length is
energized.
To use as a sonde, connect both transmitter leads to the
FlexiTrace stud terminals. As the FlexiTrace terminals are
not color coded it does not matter to which terminals the
leads are connected. To use the FlexiTrace in line mode,
connect the red transmitter lead to a FlexiTrace terminal
and ground the black lead.
