Digital Electronic Theodolite for construction

The LDT-05 digital electronic theodolite is designed for enhanced performance in construction applications. Work faster with the advanced features of the LDT-05 to improve productivity while increasing the bottom line.

Advanced features:
  • Automatic vertical compensation
    - A tilt warning occurs if out of compensation range, preventing costly errors
  • Visible laser plummet
    - Makes setting over a point a snap — much faster & easier than optical plummets
  • 5-second accuracy
    - High accuracy for tight tolerances
  • Precision dual LCD panels with large, easy-to-read numbers
    - Observe display and functions from both sides of the instrument
  • Vertical angle measuring includes percent of grade option
    - Percent of grade or degrees — your choice!
  • Auto Power-Off Option
    - If enabled, shuts off unit in 30 minutes if no activity to conserve power
  • Audible 90 degree ‘beep’
    - Emits an audible tone at for each of the four right-angle directions for faster orientation
  • Zero resetting
    - Instantly resets the horizontal angle to zero
  • The LDT-05 includes both rechargeable and alkaline battery options
