We will provide an overview of the most common equipment including Cable Locators, Pipe and Leak Locators, Valve Box & Ferro Magnetometers and Water Level Indicators. Like any tool, picking the right one for the job will help you quickly get one project finished so that you can move on to the next.

Let's get started by reviewing what to look for in a cable locating device. Cable locating detectors come in single frequency and multiple frequency configurations. They are designed to trace all conductive lines including pipes, cables and conductive electrical lines. Some units include advanced features like digital displays. In general they are all-metal devices. You will want to be sure to get a quality headphone such as the Audiophone II to go along with your device.

This will allow you to hear the deeper fainter signals clearly and easily and also block external noise.

Cable Locating Metal Detectors:

The next type of industrial metal detectors are designed to locate valves boxes, manhole covers, oil tanks and general pipe locations. The Fisher FML-3 and FX-3 are magnetometers and as such will locate iron or steel only. They are extremely sensitive and deep seeking devices. If you are looking to locate other types of metal, the Fisher M-101 and the M-97 are all-metal, metal detectors and are what you need. The draw back is that they do not go as deep as the magnetometers. Be sure to get a headphone such as the Audiophone II for use with any of the devices in this category.

Valve, Box & Ferro Magnetometers:

The next group of detection devices are pipe detection and liquid leak locating instruments. They are designed to find leaks in pipes or the actual pipes. These devices feature special technologies for pinpointing leaks even in tough conditions. Some devices include digital displays and notch filters for suppressing external noise. Be sure to get a headphone such as the Audiophone II for use with these devices.

Pipe and Leak Locating Devices:

The final category of detection equipment is water level indicating devices. These devices can be ordered in a variety of lengths depending on your specific application. They will help you accurately measure the water level in water wells and other bodies of water. Contact with water is indicated by both an audio tone and LED.

Water Level Indicators:

In summary, there are a wide variety of industrial metal detectors and detection systems for different applications. It is important to understand the differences between the detection systems to select the correct unit for your job. We hope that you now feel better equipped to pick out the best detector for your next job.
