The DT500 and DT500A are the most versatile entry-level instruments you can buy. With an IP66 waterproof rating the DT500 and DT500A operate dependably even where conventional theodolites do not, such as sudden showers, continuous drizzling rain or the high humidity of underground construction sites.
The vertical and horizontal angles are electronically read and displayed on a large, easy to read, two-line LCD display. The automatic vertical circle indexing means you can achieve a level of accuracy not possible with other instruments in this price range.
Additional features:
Optical plummet which eliminates the need for a plumb bob.
Percentage of slope or vertical angle display with the touch of a button.
Angle readings are monitored by a self-checking microprocessor and displayed in less than .5 second.
Read horizontal angles clockwise or counterclockwise: then lock with the hold/release key to hold angles.
