Description
The Greenlee BLL-200 Buried Line Locator is a compact, lightweight kit consisting of two
components—a transmitter and a receiver. The receiver can work alone for tracing buried
current-carrying conductors, or with the transmitter for tracing other conductive objects.
Applications include the following:
• HVAC (Heating, Ventilation and Air Conditioning)
• telephone
• CATV (Cable Television)
• line voltage
• fiber optic with metallic shield
• security system wiring
• conduit
• water pipe
• finding unknown conductors
The transmitter also provides the ability to measure the depth of the buried conductor.
Buried debris, underground rebar (reinforcement bar), and areas crowded with conductors can
create a challenging tracing environment. This manual provides tips and strategies to help
reduce or eliminate the difficulties caused by these circumstances. Use of the BLL-200 is
explained under Introduction and Operation. The Introduction explains some of the general
concepts of the tool, and Operation goes into more detail on the use of the tool.
