Locators Application Guide
1. 10,000 ohms and less–both ends isolated from grounds.
2. Does not locate the path–has to be predetermined and only in direct burial applications. 5,000,000 and less.
3. Transmitter connected to metallic shield.
4. Will trace coax providing the bOnd is in place at the remote end–will disrupt service.
5. No sorting (high RF bleeds) can trace coax if transmitter connected to braid.
6. 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.
7. Direct Connection 4,000 ft at 7 ft deep
Inductive Coupler 1,000 ft at 3 ft deep
Inductive Antenna  700 ft at 3 ft deep
