Reminded me of this for some reason 😃
Don’t really see what a level of this size could be used for, any ideas?
They are about as reliable as a knitted condom
Accuracy ? What are you people on ? Its a bubble ! If it looks right both ways round, you'll do.... Who checks your shelves, NASA ?
Very true. How accurately the manufacturer sets that vial of air and water into their housing can have dramatic effects on the accuracy. If you have ever used a level to draw a straight and level line across a long wall without switching the level around at intervals you will know how inaccurate even the most expensive of levels can be.
