AT-5005 
Professional 
Underground Cable / 
Pipe Locator System
Buried Utilities represent a major challenge to electricians 
who need to trace and trouble shoot such systems. They also 
represent a hazard to excavation crews. Improperly performed 
digging can cause cable or pipe damage resulting in personal 
injury, costly repairs and penalties. This product is faster and 
more accurate than what’s available on the market today. 
The AT-5005 features A-Frame attachment to pinpoint cable 
ground faults in non-destructive way. The optional Pipe 
Transmitter allows tracing and locating of non-metallic pipes. 
No hassle

Our commitment to 
high-quality products 
and customer service 
is demonstrated by 
our industry exclusive  
“No Hassle” warranty.  
In the unlikely event 
that an Amprobe Test 
Tool requires warranty 
service, any of our 
local dealers are 
authorized to replace 
it, on the spot.
(note: $500 MSLP limit)
Using superior design and powerful software, the AT-5005 
offers several new performance features, establishing them 
as the new standard for locating and pinpointing faults in the 
underground systems. Distance sensitive Left / Right indication 
guides the user to the exact location of the buried utilities 
which saves time and effort not available on standard locators. 
The Signal Select and Distortion Alert provide superior 
accuracy by visually indicating a clean signal of the traced line, 
versus “ghost” and ‘return’ path of false signals coming from 
the neighboring lines, and keeping the user on the target line.
The core of the AT-5005 Utility Locating Systems is the 
ergonomically designed handheld receiver. Designed for 
comfort, the lightweight receiver is balanced for all day use. 
The receiver’s bright color display is complete with intuitive, 
easily read graphics that can be viewed in all lighting 
conditions.

Locates underground energized and de-energized wires, cables and  ■ 
pipes, eliminates exploratory digging in parking lots or under floors for 
buried pipes and wires
New technology makes tracing much faster, accurate and unambiguous  ■ 
when compared to standard locators:    
  – Signal Select and Distortion Alert icon indicates clean signal of the  
    traced line, versus “ghost” and ‘return’ path signals coming from  
    the neighboring lines                        
  – Forward-looking Guidance Coil alerts for bends and “T”      
  – Distance Sensitive Left / Right Guidance guides the user to the  
   exact location of the buried utilities and eliminates “blind” searches  
   for the line
Three testing modes for best accuracy:    ■ 
  – Passive Power Mode (50, 60, 100 and 120 Hz) – tracing      
     energized lines conducting current                       
  – Passive Radio Mode (RF) – using surrounding radio waves to trace  
    underground object                   
  – Active Mode - T-5000 signal generator with broad frequency  
    selection between 491 Hz and 166 kHz with induction mode or  
    directly connected to the cable with test leads or optional clamp 
Active Mode Depth measurement up to 20’ (6m) ■ 
Bright Color ¼ VGA receiver graphical display and audible signal  ■
indicators provide clear reading to the user 
Strong testing signal generated by 10 Watt variable output transmitter  ■
for dependable depth and distance locating 
Powerful Digital Signal Processing in both receiver and transmitter  ■
provides outstanding performance in tracing when compared to analog 
devices
Automatic or manual gain mode allows respectively quick and easy  ■ 
tracing of the line or precise pinpointing of the fault 
Receiver Bluetooth® wireless communication for downloading relevant  ■ 
images and archiving of meaningful digital information (previous survey 
results)
Ground Fault Locating with A-Frame adapter for power and telecom  ■ 
cables (optional for AT-5000)
Precise pinpointing of buried services and exceptionally      ■ 
fast sound and meter response
Rugged durable construction, weatherproof         ■ 
and drop resistant to 3’
Includes receiver (R-5000), transmitter (T-5000),      ■ 
connection cable, ground stake, ground cable,      and  
carrying case and A-Frame
