Analog Markers

PIN Marker 130/100

It is a stick underground marker of small dimensions. The design of the PIN Marker provides the possibility of its detection in vertical as well as in horizontal positions.

For fiber optic networks, the PIN Marker 130/100 is designed so that it can be directly attached to a 7/4 mm microduct using an optical coupler. It can be attached to other sizes of microtducts by using reducers.

In other applications, it is ideal for marking important points at shallow depths.

MAR 100-LQ

MAR 100-LQ is a self-leveling underground marker designed for narrow excavations. The biggest advantage of the MAR 100-LQ is the self-leveling construction. This greatly simplifies the installation of this marker. The robust outer PE casing provides it with high resistance to mechanical damage and gives it protection even in the harshest conditions. The two holes on the sides of the marker cover are for the eventual attachment of the MAR 100-LQ to the liner by means of fixing strips.

MiM Marker 120 analog

Marker 120 analog is a passive analog marker designed for the permanent marking of the underground facilities. The external diameter of the markers is only 12 cm which means that the MiM Marker 120 analog can be used in the narrowest trenches or in the places with bad access. MiM Marker 120 analog represents the cost friendly and reliable way of marking all types of the underground facilities where the exact and clear detection is needed.

MAR 100-3D

MAR 100-3D is a spherical underground marker designed for narrow excavations. The biggest advantage of the MAR 100-3D is the spherical characteristic of its electromagnetic field. This greatly simplifies the installation of this marker. The MAR 100-3D's robust outer PE casing provides it with high resistance to mechanical damage and gives it protection even in the harshest conditions. The two holes on the sides of the marker cover are for the eventual attachment of the MAR 100-3D to the liner by means of fixing strips.
MAR 100-3D can be used as an alternative ball marker for applications where liquid inside of marker is not allowed.

Marker 2500, Long Marker

MARKER 2500, Long MARKER

Marker 2500 is a flat underground marker for universal use where marking of important points is not required. The Marker 2500 is designed to mark utility lines at a maximum depth of 1.8 m. In the past, the Marker 2500 was the most widely used method for marking all types of underground networks.

Long Marker
A flat Long Marker is designed for deep excavations. It has the advantage of a long reading range. The new marker design allows the marker to be used up to a depth of 2.5 m. It is intended to be used for marking of less important points of the underground utilities in bigger depths.
