Plumb Bob: Used to find vertical reference, no bubble level, cannot measure angles.
Sine Bar: Used with a surface plate to measure precise angles, but requires gauge blocks, not a bubble level.
Bevel Gauge: Measures and transfers angles, but manual, no bubble level, mainly for marking.
Clinometer: Uses a spirit/bubble level to measure slopes, inclinations, and relative heights, and can assess surface straightness.
