This level is perfect! I'm a builder, handyman, carpenter by trade and I'm a perfectionist. Don't get me wrong, I'm advocating this for people who need a 48 inch or greater level in the construction trade, the leveling business, or anything else that requires tighter tolerances for a longer span. This is a very reliable level and I recommend it to people who are looking for a shorter level for everyday use and are professionals. even and even those who are perfectionists.
