Rotating Laser Level PR300-HV2S

Precision and productivity made automatic.

There’s value in experience. And Hilti designers have put years of experience to work in creating the Rotating Laser Level PR300-HV2S. Plus, it’s packed with more features—like an all-in-one receiver and remote, simple controls and an “AUTO” function that streamlines tough measuring tasks.


When used in conjunction with the Automatic Tripod PRA 90 and Laser Receiver PRA 83, the Rotating Laser Level PR300-HV2S becomes a multi-dimensional tool that takes layout productivity to new levels—up to 1,969 feet, with one person, and in two planes.

Better In Practice

You’ll appreciate how easy it is to harness the following performance advantages in the field, when you request an onsite demo of the Rotating Laser Level PR300-HV2S from your Hilti representative. 

  • Take convenience to the max, with the auto-alignment feature. Simply set the tool up, press “AUTO” and watch it align perfectly.

  • Speed up operation with receiver and remote control in a single device equipped with an easy user-guided interface. 

  • Replace unreliable string lines by using auto-alignment in vertical mode. 

  • Combine with the Hilti Automatic Tripod PRA 90 for the fastest single-person height transfers.

  • Handle horizontal leveling, vertical alignment, squaring, and plotting of slopes with ease and accuracy.

  • Ensure exact depths and levels for excavations, pouring concrete, transferring heights, and more.

  • Simplify alignment of columns and facades, or transfer of building lines. 

  • Grade foundations, trenches, piping, roads, ramps, and parking lots accurately—including slopes in both the X- and Y-axis—in less time, with less manpower.

  • Protect your layout accuracy and investment with a jobsite-tough rotating laser level that resists drops from a tripod at 5 feet, and a receiver that can withstand drops from 6.5 feet when mounted in the new PRA 83 rubber housing.
