ROTARY LASER LEVEL: This rotary self-leveling leveler in the horizontal plane and manually levelling leveler in the vertical plane is a workhorse for small job sites. It features an illuminated vertical vial and changeable rotational speeds of 200; 400; or 600 RPM.
This is an excellent rotary laser level, and very simple to use. The kit has everything you need to get started. I use this for my concrete business, and could not be happier.
