The HHCL10 is ideal for pinpointing 
the location of electrical cables and 
metal, water, or gas pipes behind 
walls, above ceilings or under 
floors. It can also trace circuits, 
detect open- and short-circuits,  
find outlets covered by plaster, 
identify a circuit’s breaker, and 
locate blockages in plastic pipes. 
Makes it safe to break through 
any wall by revealing and locating 
hidden infrastructure up to 2 m 
(6.6') behind it, and eliminates the  
need to find and read construction 
drawings before starting a 
job. Transmitter and receiver 
communicate on any of eight 
channels and display readings  
on a big, bright, multi-function 
graphic LCD.
Both units also include a flashlight 
(for illuminating dark areas) and  
a buzzer that can be muted.
Transmitter has three power levels; 
receiver has variable sensitivity. 
Compatible with one- or two-pole 
circuits. Used with a metal rod, 
system can locate blockages and 
constrictions in plastic pipes.
