Product Introduction
36x HD lenses-see farther than ever
With a 45mm objective lens diameter, a wide 1°30" field of view, a short 2-meter working distance, and a wide-field, upright image, you'll see farther and clearer than ever
High-Performance Compensator Ensures Accuracy
The unique copper-bearing pendulum compensator offers superior stability, ensuring the level's accuracy, clarity, and longevity.
Compensator Warning Mechanism, Assisted Leveling
A warning indicator is located on the left side of the telescope. If the instrument's vertical tilt exceeds 5 degrees, a red warning light illuminates; once the instrument is perfectly vertical, a green line appears centered. This ensures measurement accuracy and minimizes measurement errors caused by instrument misalignment.
Horizontal Locking Screw to Reduce Lens Rotation Error
A horizontal locking screw has been added; loosening it reduces resistance to lens rotation, while tightening it secures the lens in place. This effectively minimizes displacement of the bracket beneath the lens caused by lens rotation, thereby improving measurement accuracy.
