JEAN LUTZ, by listening to their customers, developed the TLK system to provide a fast, easy and powerful method to measure the true deviation of the Kelly PILES.

The solution is the PRAD, a wireless sensor attached to the Kelly block as it descends inside the hole while digging. PRAD memorizes the acquisitions and sends to the DIALOG as it ascends once communication is established.
