●Base Type: Detachable
●Certification: GSI Certified Grade 2A
●Angle Accuracy: 3"
●Angle Measurement Method: Incremental
●Distance Accuracy: ±(3mm+2ppm）m.s.e

Smooth and reliable sighting
All fine adjustment screws and clamping screws use a coaxial design to ensure reliable one-handed sighting.
The lower fine adjustment screw features a sliding cover.
By sliding the cover only when necessary, you can prevent accidents where the horizontal dial is moved unintentionally.
