The Leica NA730 is a professional-grade automatic level engineered for contractors who demand accuracy and durability on the job site. With 30x magnification and a compensator-based leveling system, this optical level delivers reliable elevation readings across a wide range of construction and surveying tasks. Whether you're setting foundations, checking grades, or controlling structural alignment, the NA730 performs consistently in the field conditions contractors actually face.
Overview: Built for the Job Site
The NA730 is part of Leica's trusted NA series of automatic levels, designed to combine optical performance with field-ready durability. The automatic compensator self-levels within the working range, eliminating the need for manual leveling adjustments during use and reducing setup time on busy sites. The instrument is suited for elevation control on commercial and residential construction, civil grading operations, utility installation, and topographic surveys where a reliable, no-frills optical level is the right tool for the task.

Job Site Applications
The NA730 is a versatile tool across multiple construction and survey disciplines:
- Foundation Layout: Set and verify elevation benchmarks for footings and slabs with the accuracy required for structural integrity.
- Site Grading and Earthwork: Control cut-and-fill operations and verify finish grades on road bases, parking lots, and drainage swales.
- Structural Alignment: Check floor elevations, beam heights, and column bases to ensure structures rise plumb and level from the ground up.
- Utility and Pipeline Installation: Maintain consistent invert elevations for gravity sewer, storm drain, and utility trench work where slope tolerances are tight.

Frequently Asked Questions
- What is the accuracy of the Leica NA730?
- The NA730 has a standard deviation of 2.0 mm per kilometer of double-run leveling, making it well suited for construction control, foundation work, and general site grading where high accuracy is required.
- Does the NA730 require manual leveling before each shot?
- No. The magnetic dampened pendulum compensator automatically levels the line of sight once the instrument is roughly leveled using the circular vial. This speeds up setup and reduces operator error during the workday.
- What tripod does the Leica NA730 use?
- The NA730 mounts on any standard 5/8-inch surveying tripod. Leica's GST05 aluminum tripod is a compatible and commonly recommended option for stable, accurate setups in field conditions.
- Is the NA730 suitable for use in wet or dusty conditions?
- The NA730 is built with a robust housing designed to handle typical job site exposure, including dust and light moisture. For extended use in heavy rain or fully wet conditions, appropriate protection or a weather-resistant cover is recommended.
