4.6.2.1  Peak mode 

The Receiver is equipped with 

sharp peak

 

 and 

broad peak

 

 functions, which facilitate high 

accuracy of tracing depending on the depth and density of utilities in the target zone. 

Fig. 23

 shows 

the relationship between the signal level and antenna displacement from the utility.
