SeekTech SR-60
Orientation to the Signal
Because of the multiple signals being processed by each
Omnidirectional antenna, the target's signal always gets strong-
er as the receiver gets closer to the target. How the unit is held
does not affect Signal Strength. The user can approach from any
direction and does not need to know the orientation or direction
of the pipe or wire.
Locating Sondes
Used with a Sonde, the SR-60 eliminates Nulls and "Ghost Peaks".
A conventional locator signal often sees a signal increase fol-
lowed by a null (better described as no signal registering on the
antenna) and then a peak. This can confuse the operator who
may interpret a smaller peak as the target.
Figure 70: The signal from a Sonde as "seen" by a
conventional locator
The main peak is in the center, and two false peaks are out-
side the two nulls.
The SR-60 uses measurements of the complete field to direct
the user to the target. Finding a Sonde using Signal Strength is a
very direct process.

The only way to go is "up" toward the maximum signal.

More on Informational Locating
Because of the SR-60's advanced processing and display, the in-
formation provided by the SR-60 makes it clear when a locate is
reliable, and when one is suspect.
A good locator can understand the underground picture with
much less effort by using the combined information provided
by:
Proximity Signal/Signal Strength
Tracing Line
Distortion Indicator
Guidance Arrows and Directional Sound
Continuous Measured Depth indications
These indicators show what the antennas are "sensing" as they
move through the field. They signal when a field is being distort-
ed out of shape by interference from other cables, pipes, or con-
ductive objects nearby. When significant distortion is present,
the indicators will not agree. Knowing distortion is present al-
lows the operator the option of taking action to reduce it or at
least account for it. (For example, both location and Measured
Depth reading become suspect in distorted fields.)
The other side of having more information is verification that a
locate is reliable. If all of the indicators are in agreement and rea-
sonable then the degree of confidence in a locate can be much
higher.

Transportation and Storage
Before transporting, make sure that the unit is off to preserve
battery power.
When transporting, make sure that the unit is secure and does
not bounce around or get bumped by loose equipment. The
SR-60 should be stored in a cool dry place.
Note: If storing the SR-60 for an extended period, remove
the batteries completely.
If shipping the SR-60, remove the batteries entirely from
the unit.
Installing/Using Accessories
The SR-60 also comes with Sonde and Pole Markers that can be
used to mark Pole or Sonde locations above ground. There are
two (2) red markers to mark the Poles and one (1) yellow marker
to mark the Sonde. The markers can also be used to temporarily
mark points to come back to while scouting a target area or trac-
ing a line. If appropriate: replacements can be ordered from your
Ridgid dealer.
