Featuring an electronic self-leveling within ±5 degrees, it is ideal for site preparation, excavating, landscaping-terracing and retaining walls, controlling concrete pours, alignment, and plumb of concrete forms, leveling deck floors, establishing diagonals and footings for decks and patios, contour framing, and drainage.
