Flexible - practical
- measuring angles and directions on construction sites
- correct alignment of pillars, poles, scaffoldings, slipform elements and prefabricated construction elements
- simple surveying tasks, profile surveys and leveling works
- geophysical and geographical exploration tasks
- all operating elements are easy to find and guarantee quick and simple sight taking
- the FG-T3 has a rugged body, low weight and a compact design – thus turning it into an invaluable survey instrument on construction sites
Powerful telescope
- completely rotatable telescope with excellent light transmission, magnification 20x
- image: erect and true-to-side
- graticule plate: equipped with double and single reticles for exact focussing on the target, additional reticles to measure distance
- diopters on both sides of the telescope to simplify targeting
Comfortable and easy angle reading
- both the horizontal and the vertical circle are equipped with microscopes in order to take exact readings
- both scales are displayed in a single image
- circle adjustment device for circular orientation, angle measurement and transmittance of direction
Accessories
- prism eyecaps for extreme vertical angle measurement
- tribrach with optical plummet for the exact positioning above reference points
Optional
- tubular bubble level for simple leveling works
- attachable compass to determine magnetic azimuth (not part of standard equipment)
Carrying case
- made of impact-resistant materials
- attachable compass (circular, full 360 degrees)
- precision leveling rod equipment (5mm: 100601:002.22 / 10mm: 100601:001.22)
