The Sokkia SDL30 is a high-precision digital level built for surveyors who need reliable and fast measurements in the field. With a simple aim, focus, and press of a button, the SDL30 captures both height and distance readings in just 2.5 seconds. Its advanced Wave-and-Read technology tracks the leveling staff as it moves, automatically recording the most accurate vertical position. This improves accuracy and speeds up workflow, especially on uneven terrain or in dynamic job site environments.

This digital level provides consistent performance even in challenging conditions like low light or partial shade. It can detect inverted staff readings automatically, making overhead measurements such as tunnels and ceilings easy to manage without manual calculation. The SDL30 supports multiple measurement modes, including single, repeat, average, tracking, and wave-based measurements. This flexibility makes it suitable for a wide range of elevation and layout tasks.

The SDL30 is engineered with 32x magnification optics, a dot-matrix LCD display, and an internal memory that stores up to 2,000 measurements. Its rugged IPX4-rated housing resists water and dust. With a rechargeable lithium-ion battery, the unit provides up to 8.5 hours of continuous operation, ensuring you can complete full-day jobs without interruption.
