Wall Painting Locator
Wall painting locator can solve this problem very well.
First, we choose the overall display style of wall painting in the
mobile phone, then set the number, size, spacing and nail
position of wall painting, and then projected to the wall by laser.
The height and angle of projection can also be adjusted in the
mobile phone. The whole process only takes a few minutes.
We can see the position of the nail very clearly and save time.
(“+” means the position of the nail)
