As DigiRod

  • Extremely portable, universal system that eliminates the need to carry, transport, or maintain multiple grade rod types
  • Increases safety, reducing the need to lean over or go into excavations or trenches
  • Increases accuracy, the internal angle compensation system reduces errors and extra material costs due to tilted grade rods
  • Increases productivity by always having the correct rod on-hand, and eliminating tool marks on screeded concrete
  • Easy to learn, easy to use - the simple graphical display and bright backlight allow for fast readings in low light
  • Works with existing rotating lasers, increasing productivity with a fast payback

As a Rod Mounted Digital Laserometer

  • Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to "on-grade".
  • Anti-Strobe Sensor stops construction strobe lights from setting off the receiver, and eliminates phantom strikes for easier identification of true laser beam signals.
  • Large 12.7 cm (5 inch) reception height allows faster readings by acquiring the beam quickly, and makes it easier to stay in the beam.
  • Universal Reversible Clamp for square or oval rods
  • Simultaneous elevation LEDs and bright backlight reinforces the elevation display in low light for faster readings

As Handheld Laser Distance Meter

  • Increases productivity by one tool having multiple applications
  • Increases safety by allowing one person to make accurate readings in difficult-to-reach areas
  • Increases accuracy, eliminating issues with sagging or mis-held tapes at different temperatures
