There are two types of Grade & slope lasers. The first is single slope that will give you a slope in one axis at a time. The second is a dual slope laser that will give you two slopes on separate axis at the same time. Slope lasers come with different ways to adjust the grade. The first would be a manual grade slope laser that you would figure out what the grade is to be and set your detector and rod to that grade, then manually moving the beam up or down until your detector comes on to center. This type will not have a display on the laser to read grade.
The second is a dual slope this type will have a display to see the different grades on the laser and will usually be more expensive than the single slope laser. Dual slope lasers give you the option to induce a grade in both axes giving you a compound grade.
