Bosch Trapano centrale per attacco esagonale, 8 mm

I like how this one draws the horizontal and vertical lines, instead of a single point.

Great level, works very well. The only concern is when you are marking a level over a longer distance (15-20 feet), the level laser warps a couple of degrees. Place the level on a pivot and mark long lengths by pivoting on the axis and mark where the vertical and horizontal meet. This way is more accurate. To get the full range of use from this level you need to purchase a quality tri pod or the fully adjustable height mounting accessory bosch sells.

Easy setup. The laser lines are very easy to see indoors even in a brightly lit room. A real time saver.
