TraceMaster II Pipe & Cable Locator

Newly Enhanced Sensitivity

for tough to locate pipes and cables

No experience required...

  • Single-handed operation
  • 2 buttons, 2 knobs (too easy)
  • Change frequencies from the receiver

but it’s the Pro’s choice in
pipe and cable locators.

The TraceMaster II® is the professional’s choice for locating pipe and cable, but you don’t have to be a pro to use it. So even if you only have an occasional need to find pipe and cable underground, keep a Schonstedt TraceMaster® in your kit.

Locating Tips: Pipe & Cable

Determining Target Depth by
Triangulation with the MAC-51Bx

The receiver can be used for the traditional triangulation method to determine the approximate depth of a target as illustrated in below. However, when using this method it is necessary to take into account the fact that the center of the cable-sensor is located 11 inches up the receiver tube from the black tip. When the position of the target has been determined by the null, mark the spot (#1) on the ground. Hold the receiver tip on the ground at this spot, slant the instrument at a 45o angle and slowly move directly back, to one side, from the target until a second null is obtained. Now mark a spot (#2) on the ground that is directly below a point 11 inches up the receiver tube from the black tip. Measure the distance between spot #1 and spot #2. This measurement indicates the approximate depth of the target.

You should always take a depth reading on both sides of the line. If the measured distances between spots #1 and #2 on both sides of the line are not the same, there is a good chance that a nearby line is causing the two measurements to be different. Move further along the line and repeat the depth reading procedure until the measurements are the same on both sides of the line. Once two very similar measurements are obtained, the calculated depth of the cable will always be within 4 to 6 inches of its actual depth.
