The Sokkia SDL1X is a high-end digital level engineered for professionals who demand the highest precision, productivity, and reliability in leveling tasks. It delivers exceptional height accuracy, up to 0.2 mm (standard deviation based on ISO17123‑2) when paired with the Super‑Invar RAB‑Code BIS30A staff, with slightly lower accuracy using standard staffs. Featuring Intelligent Auto Focus, the SDL1X identifies and locks focus only on the coded staff, eliminating false focusing and speeding up measurements by up to 40 percent compared to manual‑focus models. It also includes a View Finder for fast and accurate alignment that reduces eye fatigue.

Safety and accuracy are further enhanced through a dual‑axis tilt sensor that disables measurement if the instrument tilt exceeds ±8.5′, alerting the user via display and beep. The instrument supports a wireless remote trigger—this prevents disturbances from touching the device and ensures stable readings. It offers generous connectivity and storage, including 10 000-point internal memory, USB and SD card slots, and optional Bluetooth wireless (up to 100 m range) for seamless data transfer.

Other notable performance specs:

• Measuring Range: 1.6 to 100 m
• Measurement Modes: Single, Repeat, Average, Rapid‑Repeat
• Measurement Time: ~2.5 s (single), ~1 s (rapid‑repeat)
• Display Resolution: down to 0.00001 m (height), precise enough for advanced surveying needs
• Optical System: 32× magnification; robust compensator with magnetic damping and ±12′ working range
• Rugged Design: Dust and water protection (IP54 or IP45 depending on spec), and long operating life—more than 9 hours with auto‑focus use
