Swanson’s mini surface level is suitable for two-axis leveling tasks that do not quite require extreme precision.
This type of level is extremely easy to use – hold or fasten it to a workpiece that needs to be horizontally parallel, and then adjust the workpiece until the level’s bubble is perfectly centered.
Although this level can be used on tables and appliances, it really earns its spot in the toolbox when used with workpieces that have very little horizontal surface area, such as wooden posts.
The Swanson surface level will set you back $5-6. Swanson describes this as “homeowner” grade, so adjust your expectations accordingly.
