The Stabila Pocket Pro Magnetic Level is a professional quality spirit level which fits in the pocket, or can be attached to a belt with the clip supplied. This little compact level has strong magnets holding the level in place on horizontal or vertical surfaces. This Stabila level is made from precisely ground aluminium, and can measure pipe surfaces with its V-groove base. Stabila Pocket Pro Magnetic is ideal for craftsman having pride in their work. The level has a robust case with aluminium core for added strength with two milled measuring surfaces on the side, and base. These professional levels allow the user to take measurements on flat and round surfaces, as both the base and lateral measuring surfaces have an extra strong rare earth magnet which is up to 5 times stronger than normal ferrite magnets. This will leave your hands free for adjusting and aligning metal objects. Accuracy in normal position & plusmn1mm / m.
