Rotary Laser Level

I need to shoot grade with a rotary laser and have never used one. I need to dig for a foundation wall and want to go down 44" from top of existing foundation for an addition. how do i go about using the laser to achieve this depth accurately?

Also, posting the same question 4 times isn't fooling anyone.

Unlike yourself, we're not idiots here.
