The UltraView LED torpedo level features a built-in LED to illuminate the bubble meniscus. The level also features a window so the bubble can be seen from the top. Rare-earth magnets keep the level attached to metal surfaces, and an anti-slip grip prevents the level from sliding when set on a surface. A ruler groove allows for a ruler or other straight edge to be inserted for longer measurements, and it also serves as a V-groove to help the level balance on pipes. Empire Level; www.empirelevel.com
