- 10,000 ohms and less-both ends isolated from grounds.
- Does not locate the path-has to be predetermined and only in direct burial applications 5,000,000 and less.
- Transmitter connected to metallic shield.
- Will trace coax providing the bond is in place at the remote end-will disrupt service.
- No sorting (high Rf bleeds) can trace coax if transmitter connected to braid.
- Low frequency locators need a "path to earth"(dirt), 5000 ft. on an open conductor and 2500 ft. on a metallic pipe at 3 ft. deep.
- Direct connection 4000 ft at 7 ft deep.
Inductive Coupler 1,000 ft at 3 ft deep.
Inductive Antenna 700 ft at 3 ft deep.
