Several models are available:

• Solid 25 mm steel rod, threaded at upper extremity, can accommodate a zinc or plastic cap (Z02-M02). Hardened steel bolts are available to protect the thread.
• Galvanized 3/4" pipe can be driven into the ground without any special instrument. Excessive length can be removed with an ordinary pipe-cutter. A zinc or copper cap can then be added (T02). Caps come with a magnet for easy detection of the marker using a conventional detector.

Specially designed bolts protect the upper extremity of the geodesic markers (BOUENF).

We also offer markers meeting federal government standards for positionning by satellite (G.P.S.)

These models are available with a selection of points.
