The 45/90 Probe, when used with the Tinker & Rasor Model PD Short Locator, allows for greater accuracy and tracing distances while locating electrical contacts and insulated joints on coated pipelines in corrosion control systems.
Use with all Model PD Receivers by simply plugging the probe jack into the "cleat" receptacle. Follow the same easy operating methods shown in the Model PD Instruction Manual for locating electrical shorts or pipe tracing.
The search coil is located in the tip of the probe head, which allows fast, accurate performance. When the search coil is in a vertical position, a sharp "null" indicates the center of the pipe or cable.
The depth of the pipe or cable can be accurately determined without the usual bending or kneeling. First locate center of the pipe or line "A" by crossing the pipe in a sweeping motion. A "null" (no signal) will mark the center of the pipe. Mark this location "A", moving 90o from the pipe with bubble centered in 45o angle gauge and holding the probe tip close to the ground until another "null"- "B" is detected. This distance from "B" to "A" less ½ of the outside diameter of the pipe will be the depth of the buried pipe.
The "probe" itself is the red sensing element, as illustrated. This elements plugs into a black telescopic handle assembly with a quick twist probe release fitting. The handle features a comfortable Neoprene grip handle and a 45o depth angle gauge on the side. A plug receptacle is located on top of the handle to accept the coiled cord from the Model PD Short Locator.
