Use a blower brush for the lenses. Never use compressed air cans (they can blow dust inside the sealed optics). Clean the tribrach (the base mount) regularly—dirt there ruins leveling.
The (Distance-Tilt-Measurement) series is a highly regarded line of electronic total stations used primarily in land surveying , construction , and civil engineering . Known for their legendary Nikon optics and rugged reliability, these instruments provide precise angle and distance measurements. 🛠️ Key Series and Models
The Nikon DTM is dust-resistant. In quarries, surveyors use it to measure stockpile volumes. The feature allows you to shoot the top of a pile without placing a prism there (using reflectorless EDM, standard on later models). nikon dtm
: Depending on the specific model, such as the Nikon DTM-322
Nikon DTM stands for Dynamic Tilt and Shift, a type of lens technology that allows photographers to control the plane of focus in a unique and creative way. The DTM system consists of a range of lenses that feature a tilting and shifting mechanism, enabling photographers to adjust the angle and position of the lens relative to the camera's sensor.

Absolutely not. While the is no longer in active production, it enjoys a robust second life. It is the perfect instrument for surveying students learning the fundamentals, for contractors on a budget, and for remote sites where a robotic station’s radio handle would just be another battery to drain.
"I was lucky to trial PhysisTM early on when working with one of its developers. Right from the start, I've found it simple to use, quick and surprisingly accurate when I compare it with my usual calculation, having read bone age x-rays for 20+ years."
PhysisTM is a convenient and reliable method to rapidly assess a patient’s bone age at the point of care. I used to flick back and forth through the Gruelich and Pyle atlas until I found an image that matched the patients X-ray, but now I can get an answer I know is accurate within a few seconds.
