Laser-Assisted Construction Surveying

The KT02-FL combines conventional electronic theodolite functions with laser-assisted positioning. The visible laser can provide a practical reference during construction alignment, while the laser plummet helps the operator position the instrument accurately over a survey point.

Its dual LCD layout and straightforward keypad are designed for routine field work, making the instrument suitable for construction crews and surveyors who need reliable angular measurement without the added complexity of a total station.
