FAQ

Q1: What types of underground utilities can the TC-700 locate?
A: The TC-700 locates buried metal power cables, communication cables, fiber optic 
cable conduits, water supply and drainage pipelines, natural gas pipelines, oil 
pipelines, and can identify cable ground faults.

Q2: What is the maximum detection depth of the TC-700?
A: The TC-700 can detect buried utilities at depths of up to 20 meters, making it 
suitable for locating deeply buried infrastructure in urban and industrial environments.

Q3: Why does the TC-700 have 31 signal frequencies?
A: Different frequencies penetrate soil differently and interact differently with 
various utility materials. Having 31 selectable frequencies allows the operator to 
choose the optimal frequency for the specific utility type, soil condition, and 
depth — maximizing detection accuracy and minimizing interference.

Q4: What is SS phase signal identification?
A: Intelligent SS (Selective Signal) phase identification is an advanced signal 
processing technology that distinguishes the target utility's signal from background 
interference and adjacent utilities — significantly improving location accuracy in 
congested underground environments.

Q5: Can the TC-700 locate fiber optic cables?
A: The TC-700 locates fiber optic cables via their metallic conduit, armor, or 
messenger wire. It cannot directly detect non-metallic fiber cables without a 
metallic tracer element.

Q6: Is the TC-700 weatherproof for outdoor use?
A: Yes. The TC-700 is IP-rated for dustproof and weatherproof operation, making 
it suitable for outdoor field use in various weather conditions.

Q7: What does the TC-700 system include?
A: The TC-700 is a complete system including a signal transmitter and receiver 
unit, enabling both active signal injection and passive detection modes for 
comprehensive underground utility locating.

Q8: What warranty period does TC-700 have?
