Tinker & Rasor MK-5/S - Mark V Ranger Pipe Locator / Short Locator

The Tinker & Rasor MK-5/S is effective in locating shorts or undesirable electrical contacts to a buried coated pipe. Such electrical contacts should be removed prior to placing a pipeline under cathodic protection, as these contacts would drain a large amount of protective potential from the coated pipe.

The method of locating shorts or contacts on a coated pipe is that of applying AC audio-frequency energy between the pipe and a remote ground connection. A traverse is made along the pipeline with a receiver equipped with a search coil. A short or contact is observed along the traverse where the average AC signal picked up over the line suddenly drops to a very low level. This is assumed to be a point directly above the contact.

Optional PD-5 oscillator

Although the Mark V has the potent combination of Power and Sensitivity this can be radically enhanced with the addition of the PD-5 Auxiliary Oscillator. This 25 watt powerhouse has been known to supply enough energy to a well coated pipeline to allow cross country surveys of 15 miles from a single connection point. The PD-5 Fits into the Mark V and allows the Mark V to close while the PD-5 is in place.

Optional 45/90 probe

This optional probe gives the operator a search coil much closer to the ground, saving the back strain of bending over on difficult locates. The 45/90 also makes depth determination much easier.

Easy to operate and unaffected by surface cover. Its lightweight telescoping handle is ruggedly constructed and water resistant.

Optional bumper probe

The BP-1 (C) is designed for use with T&R audio frequency locators. The probe and optional clamp attach to a vehicle, usually the bumper, and allow pipeline location while driving. The probe comes with a 25' (7.62m) cable which can be run into the passenger area of the vehicle and attach to the locator receiver.

The Vehicle clamp holds the probe in 90° and 45° angles for pipeline locating, center and depth determination.
