Locator with removable antenna portion
View Patent ↗A locator is disclosed that includes a base module and an antenna module. The base module and antenna module are coupled both mechanically and electrically at a joint. Such an arrangement allows for easy stowage and shipment of the locator as well as the ability, by interchanging antenna modules, to provide multi-functional locators.
1. A locator that locates underground objects, comprising:
a base module; and
an antenna module,
wherein the base module and the antenna module are electrically and mechanically coupled in a removable fashion to form the locator; and
wherein the locator is able to locate underground objects only when the base module and the antenna module are coupled.
2. The locator of claim 1 , wherein the locator is a line locator that locates underground conductors.
3. The locator of claim 1 , wherein the locator is a marker locator that locates underground markers.
4. A base module of a locator, comprising:
electronics for receiving and processing data from an antenna module to locate an underground object;
an electrical coupler for accepting an electrical connection to the antenna module; and
a mechanical coupler for mechanically coupling to the antenna module;
wherein the base module is able to locate an underground object only when coupled with the antenna module.
5. The base module of claim 4 , wherein the locator is a line locator that locates underground conductors.
6. The base module of claim 4 , wherein the locator is a marker locator that locates underground markers.
7. An antenna module for a locator, comprising:
at least one electromagnetic field detector;
an electrical coupler for accepting an electrical connection to a base module, the base module receiving signals from the at least one electromagnetic field detector to locate an underground object; and
a mechanical coupler for mechanically coupling to the base module;
wherein the locator is able to locate an underground object only when the base module and the at least one electromagnetic field detector are coupled.
8. The antenna module of claim 7 , wherein the locator is a line locator that locates underground conductors.
9. The antenna module of claim 7 , wherein the locator is a marker locator that locates underground markers.
