Spectra Precision HL750 Receiver Sensor

  • Digital readout of elevation – not only will high or low arrows be displayed, but the exact distance from grade will be numerically displayed, which eliminates the need to get “on-grade” to make measurements
  • Large 12.7 cm (5 inch) reception height acquires the beam quickly and makes it easy to stay in the beam
  • Works with another HL750 for long range wireless remote display and monitoring – even when the second receiver is out of sight (up to 80 m or 260 ft.)
  • Machine operators can monitor elevation shots taken by another person or foremen can monitor elevations and cut/fill readings from anywhere on the jobsite
  • Anti-strobe sensor stops construction strobe lights from setting off the receiver, and makes it easier to identify true laser beam signals
  • Multiple deadband setting allows adaptation to meet all your jobsite requirements
  • Dust and weatherproof housing withstands a drop of up to 3 m (10 ft) onto concrete for reduced downtime
  • Two clamp positions for cut/fill or excavation. Excavation mode puts more reception height and elevation information above grade for higher utilization in digging and staking applications
