Description
The FCST-MB series spherical Marker Balls induction coil is suspended above the antifreeze inside the sphere. Regardless of the sphere's movement, the coil maintains a horizontal, upward-facing orientation, providing excellent positioning accuracy. Installation is straightforward, eliminating the need to consider the sphere's orientation and simplifying the process.
The FCST-MB series spherical Marker Balls are designed and manufactured to international standard frequencies and are compatible withUnderground Marker Locator (EX.ID version) also designed and manufactured to international standard frequencies. A detailed product list is provided below.

Construction Suggestions
The FCST-MB series spherical Marker Balls are installed above pipes. Due to their internal self-balancing design, there is no need to deliberately keep them level. Non-metallic pipes can be directly attached to the pipe and fixed with cable ties. When covering the pipe with soil, fill the gap between the marker and the pipe with sand or soil to avoid uneven stress on the marker after covering the pipe with soil.
Considering the uncertainty of the thickness of the cover soil in the later stage, it is generally recommended that the burial depth be less than 80% of the maximum detectable depth of this model.(See the PIG2 image.)

In the case of straight-line distances, to avoid interference between marker balls, the distance between two adjacent underground electronic marker balls should be greater than 1.5 meters and less than 50 meters.(See the PIG3 image.)
For notable points, buried cable marker balls need to be placed at the corresponding locations.Whether gas, electricity, telecommunications, district heating or water, a network typically includes notable points, which also represent points of weaknesses:
• Buried “dead ends” e.g. water connection points or micro ducts to be connected later
• Fiber Optic Splice Closure or buried branch
• Repairs or splices
• Crossover Network
• Change of direction or depth and degree of change
These points are usually difficult if not impossible to spot from above ground by the field teams unless they were recently excavated. The positioning of passive markers in key locations allows stakeholders to identify these locations quickly and positively, differentiating them from the rest of the network.

If the pipe is metal, the marker must be at least 120mm away from the top of the pipe, and there must be no metal object covering the fiber ball markers.(See the PIG4 image.)
PIG4-Metal pipe installation scene demonstration
If it's a plastic pipe, secure it directly with cable ties and install the fiber locator ball above the pipe. The following three situations will cause problems with marker ball recognition:
Situation 1: The marker ball is installed below the pipe.
Situation 2: The marker ball is installed above the pipe, but there are metal objects in the soil-covered area, interfering with the test.
Situation 3: The marker ball is installed directly below the object being marked.
