The Leica NA724 Automatic Level delivers the optical precision and field-ready durability that professional contractors and surveyors demand on high-stakes jobsites. With 24x magnification and a standard deviation of 1.2mm per 100 feet, the NA724 produces reliable elevation readings for finish-floor layout, site grading, drainage verification, and structural monitoring. Whether you're setting benchmarks on a commercial pour or checking differential settlement on an existing structure, the NA724's compensator-stabilized optics maintain accuracy across variable site conditions—giving you confidence in every rod reading without repeated backchecks.
Built for the Demands of Real Jobsites
Leica engineered the NA724 as a workhorse instrument capable of handling the daily rigors of production construction while maintaining the measurement integrity that licensed surveyors require. The sealed, dust-resistant body protects internal optics from concrete dust, soil particulate, and jobsite moisture. The magnetic damping compensator self-levels within a 15-arcminute range, eliminating human error introduced by minor tripod settling or ground vibration. From high-rise foundation layout to road subgrade verification, the NA724 performs consistently across elevation differences that demand a dependable optical baseline.

Job Applications
Finish Floor Elevation Control: Establish and transfer accurate floor elevation benchmarks across large concrete pours, ensuring slabs meet specification tolerances for flatness and drainage before the pour begins and during finishing operations.
Site Grading and Drainage Slope: Verify subgrade elevations and confirm positive drainage slopes across parking lots, athletic fields, and building pads where even minor elevation errors cause long-term drainage failures and warranty claims.
Structural Settlement Monitoring: Establish baseline elevation readings on building corners and column bases, then recheck periodically to detect differential settlement before it reaches critical thresholds—essential for forensic documentation and owner reporting.
Roadway and Utility Layout: Set grade stakes for road subbase compaction, confirm pipe invert elevations in trench bottom, and verify manhole rim elevations against design drawings during utility installation and paving operations.

Frequently Asked Questions
- What is the accuracy of the Leica NA724?
- The NA724 achieves a standard deviation of 1.2mm per kilometer in a double-run leveling loop per ISO 17123-2, which translates to reliable sub-millimeter elevation control suitable for most construction and civil survey applications.
- Is the Leica NA724 suitable for professional surveying work?
- Yes. The NA724 meets the accuracy and optical quality standards required for construction surveying, site grading, and general civil layout. For precise geodetic or monitoring surveys requiring sub-millimeter loop closures, Leica's higher-specification digital levels may be more appropriate.
- What tripod does the Leica NA724 use?
- The NA724 mounts on any standard tripod with a 5/8-inch by 11 thread fitting, which is the industry-standard connection used by most professional surveying tripods. Leica's own aluminum and wood tripods are fully compatible.
- Does the NA724 come with a warranty?
- Leica Geosystems instruments are backed by a manufacturer's warranty covering defects in materials and workmanship. Contact Express Tools or visit our warranty page for current coverage terms and Leica's authorized service center locations.
Frequently Asked Questions
What is the accuracy of the Leica NA724?
The Leica NA724 achieves a standard deviation of 1.2mm per kilometer in a double-run leveling loop per ISO 17123-2. In practical construction terms, this provides reliable sub-millimeter elevation control across typical sighting distances, making it suitable for finish-floor layout, grading, and structural monitoring applications.
Is the Leica NA724 suitable for professional surveying work?
Yes. The NA724 meets the optical quality and accuracy standards required for construction surveying, site grading, and general civil layout work. For high-precision geodetic surveys or deformation monitoring requiring the tightest possible loop closures, Leica's digital level series offers additional capability, but the NA724 handles the vast majority of production construction survey tasks with confidence.
What tripod does the Leica NA724 use?
The NA724 is compatible with any tripod featuring the standard 5/8-inch by 11 thread mounting connection, which is the universal fitting used across professional surveying equipment. Leica's aluminum and wooden tripods are fully compatible, as are most third-party professional surveying tripods available through Express Tools.
Does the NA724 come with a warranty?
Leica Geosystems instruments are backed by a manufacturer's warranty covering defects in materials and workmanship. Express Tools is an authorized Leica dealer, so instruments purchased through us are eligible for full manufacturer warranty support.
