Owner's Manual

The Topcon DT-307 Series weathers any wet or dust conditions in the field, allowing for a more productive day during inclement weather. The degree of protection against water is based on the standard IEC60529, whose definition is "water projected in powerful jets against the enclosure from any direction shall have no harmful effects".

All models are also compact and lightweight for easy portability; and their simple operation provides precise measurement in a functional, hassle-free package. The Topcon DT-307 Series allows for more than 140h of continuous measurement in the angle mode. This long battery life will eliminate the necessity for the replacement batteries on the job.

Add a whole new dimension of accuracy and confidence to your alignment jobs with Topcon's unique DT-307 Series featuring a red Class II laser beam. Use it anywhere on your site and see clearly in direct sunlight up to 165 ft. Now you can easily and accurately place anchor bolts at regular intervals on a line, set an angle, and use the beam to verify your tape measure is properly aligned for the next stake, or "sight in" footers, frames, and tilt-up walls.
