The DIGISYSTEM and the DIGICAT
DIGITRACE
This accessory is connected to the DIGITEX, and can be used in two modes: Line mode where
a signal is impressed on the length of the DIGITRACE, and sonde mode where just the tip
emits the signal.
For tracing non metallic pipes and conduits.
Operates at 8 and 33 kHz modes.
DIGIMOUSE
The sonde of the DIGISYSTEM. This battery powered transmitter is used in conjunction with
standard drain rods. It is then traced using the DIGICAT.
For tracing non metallic pipes and conduits.
Operates at 33 kHz mode.
Locating with the DIGITEX
There are two DIGITEX modes, both of which are available in 8 or 33 kHz:
• Induction
• Connection.
The advantages of using induction mode are that it is quick and simple to use, and a signal
can be applied to a service without having to make any physical connection to it. The disad-
vantages are that the risk of cross - coupling (the signal applying itself to more than one
service) to adjacent services is high, and part of the signal strength is lost in the surrounding
soil.

33 kHz provides the best coupling efficiency.
