1. A portable locator comprising:
- at least two antenna nodes each having at least three substantially orthogonal coils;
a plurality of supports, each support connected to a corresponding one of the antenna nodes;
means for permitting the supports to be pivoted to vary a spacing between the antenna nodes;
a housing connected to the pivoting means; and
processing means at least partially mounted in the housing for receiving signals from the coils induced by electromagnetic emissions from a buried object, determining a location of the buried object, and providing an indication of the location.

10. A portable locator comprising:
-
at least two antenna nodes each having at least three substantially orthogonal coils; a plurality of supports, each support connected to a corresponding one of the antenna nodes; an assembly that allows the supports to be pivoted to vary a spacing between the antenna nodes; a housing connected to the assembly; and processing circuitry at least partially mounted in the housing capable of receiving signals from the coils induced by electromagnetic emissions from a buried object, determining a location of the buried object, and providing an indication of the location.
