DANGER

 

Important Notice 

The SeekTech ST-305 is intended for use with a 
SeekTech locator/reciever. The locator is a 
diagnostic tool that senses electromagnetic fields 
emitted by objects underground. It is meant to aide 
the user in locating these objects by recognizing 
characteristics of the field lines and displaying them 
on the screen. As electromagnetic field lines can be 
distorted and interfered with it is important to verify 
the location of underground objects before digging. 

Several utilities may be underground in the 
same area. Be sure to follow local guidelines 
and one-call service procedures. 
Exposing the utility is the only way to verify its 
existence, location, and depth. 
Ridge Tool Co., its affiliates and suppliers, will 
not be liable for any injury or any direct, 
indirect, incidental or consequential damages 
sustained or incurred by reason of the use of 
the  SeekTech ST-305.
