The TraceMaster II is Schonstedt's most versatile
locating tool. It is an ideal choice when:
• There is significant volume of underground
locating work to do
• The underground environment is congested with
multiple utilities
• Excavation projects are medium to large size
• Terrain and/or soil type are challenging
• Distances are long (over 300 feet)
The Schonstedt TraceMaster consists of two parts: a
Transmitter and a Receiver. The TraceMaster is used
to locate things underground such as pipes and
electrical lines, although the TraceMaster cannot
locate plastic pipe. The TraceMaster uses different
frequencies to locate different utilities. The
passive mode does not use the transmitter. Instead
the receiver searches for 50/60 Hz signals such as
those from live power lines. In the active modes the
transmitter operates at four different frequencies:
low (575 Hz), mid-range (8 kHz), high (82 kHz), and
very high (455 kHz). The receiver can determine the
approximate depth of the target, and has the ability
to operate in manual or automatic gain modes.
The different TraceMaster II models options
include;
AF- Means “All Frequencies” this model is able to
operate on all the frequencies available. The
frequencies can be changed from the transmitter or
the receiver via a built-in radio link.
SF- Means “Single Frequencies” this model is able to
operate on one frequency, which is selected when the
item is purchased.
PF- Means “Passive Frequency” this model does not
come with a transmitter. And can only be used in the
passive mode. The passive mode is used to detect
live power lines only.
What Hertz or Frequency do I need?
Passive Frequency - In the passive mode the
transmitter shuts down its output and the receiver
searches for 50/60 Hz signals, from AC power off
live buried cables and pipes.
With four classes of frequencies, the TraceMaster
is the most versatile locator on the market. The
Active Frequencies Include:
Low Frequency (575 Hz) - This frequency will not
jump to adjacent conductors and can only be induced
with the conductive clips connected directly to
access points on the utility to be traced. The low
range frequency is the best choice for tracing over
long cable lines.
Mid-range Frequency (8 kHz) - This frequency will
not usually jump to adjacent conductors, but may
jump across non-conductive joints in a pipe for
longer tracing. It can only be induced with the
conductive clips connected directly to access points
on the utility to be traced, or the optional
inductive clamp. Medium range frequencies are
generally the most useful range for location.
High Frequency (82 kHz) - This frequency can
typically jump to adjacent conductors and can be
induced by the conductive clips, the optional
inductive clamp, or the built-in inductive antenna.
This frequency is best for larger pipes such as
water and gas lines. If the signal is weak during
the beginning of a trace, you can switch to a higher
range frequency.
If you are purchasing the single frequency
TraceMaster and need to select just one frequency to
detect electrical, water and gas lines it is better
to use the high
frequency of 82 kHz.
Very High Frequency (455 kHz) - This frequency can
easily jump to adjacent conductors and it is a good
frequency to use for total field survey or "quick
scan" of a small area. It can be induced by the
conductive clips, the optional inductive clamp, or
the built-in inductive antenna. Very high range
frequencies are good for rapidly sweeping for all
utilities in a congested area.Hopefully this
article helps you quickly get an understanding of
how the Schonstedt TraceMaster is made, how it
works, and how it is sold.
