The orange 3M EMS Spherical Marker - Telephone makes marking and subsequently locating underground telephone lines with the 3M Dynatel marker locators extremely easy. It can be located to a maximum depth of 1.50 metres, is insensitive to minerals, chemicals and temperature changes and is therefore suitable for all types of soil. The free-floating design in a watertight PE sphere ensures that the marker always aligns itself exactly horizontally, regardless of the installation position. The liquid inside the sphere is a mixture of water and propylene glycol, which is biodegradable and harmless to humans, fauna and flora. The electronic markers are regarded as the most reliable method of marking existing or newly installed facilities - even under snow. Their function is not affected by metal ducts or pipes, fences or high-voltage power lines.
