0° Hummer / Hummer

0° Hummer
0° Hummer

When knocking in something with a hammer, it’s difficult for people to find out the horizontal line without hinting by others. As a result, the things knocked in the wall are often not consistent in height. 0°Hummer can assist the user to find out the horizontal line and the vertical line. When people have knocked in the first nail in the wall, they can put the bottom of the hammer against the wall to trigger the switch on the bottom, thus radiating a ray vertical to the horizontal line on the wall. Users can confirm the position of the next nail by relying on the positon of the first nail shone by the ray.
