Sokkia RAB-Code Barcode Staff Grade Rod (SDL Digital Level Rods)

Overview

The Sokkia RAB-Code Barcode Staff Grade Rod is a precision leveling rod designed exclusively for use with Sokkia SDL digital levels. Using Sokkia’s proprietary RAB-Code (Random Bidirectional Code) technology, these staffs allow digital levels to automatically read height measurements, improving accuracy and eliminating manual reading errors.

Available in multiple lengths and configurations, these rods are built for professional surveying and construction applications. Most models feature rugged fiberglass construction for durability and waterproof performance, while select models are available in aluminum.

Built for Digital Level Accuracy

Sokkia’s RAB-Code system allows SDL digital levels to automatically read the staff, reducing human error and increasing measurement consistency. This is especially important for high-precision leveling tasks where accuracy and repeatability are critical.

Dual-Sided Functionality (BGS50-G3 Model)

The BGS50-G3 model features dual-sided graduations:

• One side: RAB-Code in centimeters for digital level reading
• Other side: Feet, tenths, and hundredths for traditional measurement

This makes it a versatile option for crews working across both digital and conventional workflows.

Durable and Field Ready

Constructed primarily from fiberglass, these rods are built to handle harsh jobsite conditions. The waterproof design ensures long-term durability, while the telescopic sections allow for easy transport and compact storage.

Applications

• Digital leveling with Sokkia SDL series
• Construction elevation checks
• Control point establishment
• Surveying and engineering projects
