Spectra Precision M302 Wall and Ceiling Mount / Bracket

Overview

The David White AL8-32 Automatic Level Package delivers professional-grade leveling performance for contractors, surveyors, and construction professionals who demand accuracy and reliability on every job site. This complete kit combines the proven AL8-32 32-power automatic level with a high-visibility inches rod and sturdy aluminum tripod, creating an immediate-deployment solution that eliminates the need for separate component purchases. With its compensator-stabilized line of sight and weather-resistant construction, this package provides consistently accurate measurements across residential construction, site grading, foundation work, and landscape applications. The AL8-32's 32x magnification power enables precise readings at extended distances while maintaining the clarity needed for tight tolerance work. Whether you're establishing grade for a new foundation, setting forms for concrete pours, or conducting topographic surveys, this turnkey package arrives ready to set up and start measuring. The included inches rod makes this kit particularly valuable for domestic construction projects where imperial measurements streamline communication and reduce conversion errors. At $354, this package represents exceptional value by bundling three essential components at a price point significantly below purchasing items individually.

What's in the Kit

• David White AL8-32 Automatic Level: Main instrument with 32x magnification and automatic compensator system
• 13-Foot Inches Measuring Rod (Model 45-8932-1C): Graduated in feet, inches, and eighths with high-contrast markings for visibility
• Adjustable Aluminum Tripod: Heavy-duty tripod with extendable legs, pointed shoes, and 5/8-11 mounting thread
• Protective Carrying Case: Padded hard case for instrument protection during transport and storage
• Lens Covers: Objective and eyepiece protective caps to prevent scratches and dust accumulation

• User Manual: Complete operating instructions with setup procedures and maintenance guidelines
• Manufacturer Warranty Documentation: Coverage details and registration information

Job Applications

• Residential Foundation Work: Establishing level reference points for foundation excavation and formwork ensures proper drainage and structural integrity. The inches rod eliminates measurement conversion, reducing errors when communicating with concrete crews who work exclusively in imperial units.
• Site Grading and Drainage: Determining existing elevations and establishing finish grades for proper water runoff protects structures from moisture damage. The 400-foot working range covers large residential lots from a single setup position, improving efficiency on grading projects.
• Concrete Flatwork and Slabs: Setting screeds and checking slab elevations during pours guarantees level finished surfaces for floors, driveways, and patios. The 32x magnification allows clear rod readings even across long pours, maintaining accuracy as crews work across the surface.
• Landscape Construction: Installing retaining walls, terracing, and irrigation systems requires accurate elevation measurements to ensure proper function and appearance. The automatic compensator maintains accuracy even when the tripod settles slightly on soft ground during extended measurement sessions.
• Deck and Patio Installation: Establishing level building platforms and checking post heights creates structurally sound outdoor living spaces. The minimum 3.3-foot focus distance enables measurements in tight spaces between existing structures.
• Building Addition Layout: Matching new construction to existing building elevations requires precision measurements at multiple points. The included complete package means arriving on-site with everything needed rather than discovering missing components mid-project.

Compatible Accessories

• Grade Rods: Metric graduated rods, direct elevation rods, and extended-length options for specialized applications
• Leveling Rod Accessories: Rod targets, rod levels, and extension sections for increased measurement range
• Tripod Upgrades: Heavy-duty wood tripods and quick-setup models for different working conditions
• Carrying Solutions: Soft carrying cases, backpack-style carriers, and vehicle mounting systems
• Maintenance Items: Lens cleaning kits, replacement covers, and calibration tools
• Measurement Tools: Stadia rods, turning points, and hub stakes for extended survey work

FAQ

What's the difference between an automatic level and a transit?

An automatic level uses an internal compensator that automatically maintains a level line of sight when the instrument is approximately level, making it faster to set up and easier to use than a traditional transit. Transits require manual leveling using bubble vials and are primarily used when vertical angle measurements are needed, while automatic levels excel at efficient horizontal leveling work like the AL8-32's construction applications.

Can this level be used for foundation work on sloped lots?

Yes, the David White AL8-32 is ideal for sloped lot foundation work. The tripod adjusts to provide a stable platform on uneven terrain, and the 400-foot working range allows you to establish benchmark elevations and measure multiple points across the slope from a single setup. The automatic compensator works within ±15 arc minutes, accommodating the tripod positions needed on challenging terrain while maintaining measurement accuracy.

How do I know if the automatic compensator is working correctly?

After setting up and leveling the instrument using the circular bubble, gently tap the telescope while looking through the eyepiece at the rod. You should see the crosshair image move slightly then settle back to the same position within a few seconds—this indicates the compensator is freely operating. If the crosshair doesn't return to exactly the same position or doesn't move at all, the compensator may require service or the instrument may be outside its working range and need releveling.

What accuracy can I expect at different distances with this package?

The AL8-32 provides ±1/16 inch accuracy at 100 feet under normal conditions. At 200 feet, expect approximately ±1/8 inch accuracy, which is suitable for most construction applications. Beyond 200 feet up to the 400-foot maximum range, atmospheric conditions, rod visibility, and reading technique become more significant factors. For critical measurements beyond 200 feet, take multiple readings and minimize heat shimmer by measuring during cooler morning hours.
