tracing over longer distances). The mode is selected depending on
which is most effective under the locating conditions.
The receiver includes four volume settings, including a special
“expander” function that makes peaks and nulls more pronounced.
The expander feature enhances the amplitude difference between
two conductors carrying the same signal, making the unit extremely
accurate, even in congested areas. A headphone jack is also
A simple, easy-to-use system
The Dynatel 2250 Advanced Cable Locator is easy to operate and
requires very little training. Digital liquid crystal display (LCD) readout
and push-button operation make the unit easy to understand, for
more precise locates.
A “memory” feature remembers operator set-up from previous use.
The system consists of two basic components:
• Transmitter with built-in ohmmeter, which also senses and

The 2250 cable locator uses four active trace frequencies — 577 Hz,
underground cables, both copper and fiber optic (with metallic
8 kHz, 33 kHz and 200 kHz — which can be used individually or
trace wire). Lightweight, compact and well-balanced, the locator

• Measures cable or sonde depth with the push of a button
Both the receiver and the transmitter feature a self-test routine which
• Measures signal current in the cable
is executed each time the unit is turned on.
• Identifies cable and cable pairs
A power-up battery test indicates battery level.
• Identifies cable pairs through wet sections
Both components are constructed of heavy-duty materials designed
• Locates energized power cable with direct readout of cable depth
to withstand typical field use.
The 2250 cable locator provides accurate cable or sonde depth
measurements, giving a digital readout in inches, feet

Four modes of operation for accurate locates, even in
congested areas
For cable path locating, the Dynatel 2250 receiver uses one of four
user-selected locating modes – dual peak, dual null, differential
or special peak (which increases the sensitivity of the receiver for
