Measures Longer and longer, Improvement Never Settles! How could we lift the ranging cabability to a new level of 1000m? The three key factors are “Dual-light Source Distance Measuring technology”, optimization of the signal-to-noise ratio, a more stable objective lens system.

| A New Step to be More Accurate,
Innovation Never Stops!
Every hard working surveyor deserves a higher precision than before. Four innovations have been realized in our newly designed optical system to achieve this goal: “Focal Length Compensation Mirror”, “Fully sealed emitting laser circuit”, “Less reflectors in optical part”, “the 4th Generation EDM CPU”. |
