Intelligent Auto Focus

• The SDL1X automatically focuses exclusively on the RAB-Code staff.
• This technology completely eliminates false focusing on undesirable objects, enhancing measurement efficiency and reliability.
• Furthermore, Auto Focus eliminates the incomplete focusing that often causes inaccurate measurement with digital levels.

Remote Trigger

• The wireless Remote Trigger DLC1 prevents accidental jolts from touching the instrument.

Dual-axis Tilt Sensor 

• The liquid dual-axis tilt sensor alerts the users by LCD display and beeps when instrument tilt exceeds +-8.5', disabling measurement to avoid misreading
• The LCD graphic circular level facilitates instrument setup.

Measurement and Recording Programs

• Onboard software supports height difference measurement and data recording in the following procedures: BF, BFFB, BBFF, BFBF, aBF, aBFFB, aFBBF (B=Backsight, F=Foresight, a=alternating)
• Measurement tolerance can be set in each route for on-site accuracy checks.

Up-to-date Data Memory and Interface

• 10,000-point internal memory.
• USB port and SD card slot for improved usability.

100m (320ft) Bluetooth Wireless Modem (Optional)

• License-free Bluetooth technology enables wireless operation via various devices such as a data collector.

New Super-Invar Starr for 0.2mm Precision 

• The SDL1X achieves the highest in precision when combined with the New Super-Invar RAB-Code Staff BIS30A that boasts the industry's lowest linear expansion coefficient +-0.1ppm/°C.
• Ideal for first-order leveling as well as sub-millimeter height and subsidence measurement applications. 

Supplied with:

• BDC58 Li‐ion battery, CDC68 115VAC Charger, DLC1 Remote Trigger, dust cover, tool kit, operator's manual, carrying case.
