Thanks to a rugged design and clever single button operating concept, the Hilti PRE 3 is extremely robust and easy to use. Featuring “Hilti Pulse Power” with a frequency of one million pulses per second, a single pass of the laser beam is all that’s needed to ensure reliable detection of the beam by the receiver for superior performance, even under the most difficult conditions. Designed from the outset with the user’s needs in mind, the entire PRE system makes it easy to work efficiently and with great accuracy. Well cushioned all round, the laser receiver is not only shockproof it also incorporates a large display and a practical tape measure.
