Regardless which Stabila level you use --- R-Beam, 96/196, XTL or even 106T --- it's only designed to tell you one thing: either your work is level or it's not. But if you work in the real world and have to fit your work to existing out-of-level/plumb conditions, a new precision level accessory, the HOW FAR OUT level gauge, can tell you EXACTLY how far out things are. Check it out at www.howfarout.com For installations, renovation, or remodeling in older buildings, the How Far Out level gauge and positioning device turns your level into a precision survey instrument by adding a level adjustment screw and integrated inch/metric scale. The CNC machined gauge snaps on and off magnetically, and extra adapters are available to allow one gauge to be used on multiple levels. Re-calibrating your Stabila electronic level has never been more accurate or easier than when you use the How Far Out gauge as a positioining device to dial it into perfect position.
