Spectra Precision AL24M Automatic Level

The Spectra Precision AL24M is a durable and dependable 24x magnification automatic level designed for elevation control, site layout, and general construction applications. Built with a magnetic dampening compensator, the AL24M is ideal for use in vibration-prone environments, such as busy job sites or areas near heavy equipment. It provides ±2.0 mm accuracy per kilometer of double-run leveling and a leveling precision of ±2.5 mm at 50 meters, making it well-suited for cut/fill tasks, landscaping, and basic layout work.

The AL24M features erect image optics, a 30 mm objective lens, and a 1°20' field of view, providing clear visuals even in low light. It has a short minimum focusing distance of 0.60 m (1.97 ft.), allowing it to perform well in tight workspaces. The integrated stadia lines, horizontal angle scale, and double-sided tangent drives allow quick measurements and easy target alignment from either side.

Each AL24M is housed in a rugged metal body and comes with a plumb bob, adjustment tools, rain hood, and hard-shell carrying case—ready for use right out of the box or as part of a complete package with tripod and grade rod.

Air vs. Magnetic Dampened Compensators

The AL24M uses a magnetic dampening system, which is ideal for high-vibration environments where quick, stable leveling is critical. Magnetic systems are less sensitive to sudden movement and recover quickly, making them excellent for use on active construction sites.

In contrast, air dampened models (like the AL24A) are designed for higher-precision applications and smoother environments, such as surveying or engineering layouts. Choose magnetic for rugged reliability, and air for fine accuracy where conditions allow.
