Rapid, Stable, and Durable Performance – The AT-B4’s advanced compensator uses four high-tensile suspension wires for exceptional accuracy and durability, while its magnetic damping system ensures quick stabilization, even in high-vibration environments.

Easy Angle Measurement – The horizontal circle allows 1° or 1 gon readings with free rotation for quick and precise angle measurements. A protective cover prevents dirt and scratches, while the conveniently placed readout window enhances usability.

Short Minimum Focus (20 cm) – Work efficiently in tight spaces with a short 20 cm focusing distance, allowing for precise measurements in confined areas.

All-Weather Reliability – IPX6-rated for water resistance, the AT-B4 withstands heavy rain and harsh conditions while preventing internal condensation for consistent performance.
