M-D SmartTool Digital Spirit Level Module - 21.8 cm (includes cover)

Features

Simple to use
Smart Tool permits you to find level and plumb in two ways.  For quick references, use the sensitive bubble vials. For highly precise work, use the digital display on the Sensor Module.  It provides accuracy to 1/10 of a degree. But the real advantage of the SmartTool is that it also reads all the other angles bubble vials don't.  So when you are not dealing with level or plumb, SmartTool quickly tells what the angle is and what the angle needs to be.  And only SmartTool allows you to measure angles three different ways: degrees, percent slope, and pitch (rise over run).

Read in Degrees
Set saw blade angles to a fraction of degree accuracy with SmartTool.  Assure there is no gap when you join 2 cuts together with .1 degree accuracy. You can easily duplicate a stair angle for setting handrails and never again will you be measuring top and bottom to make sure stair treads and rails are parallel.

Percent Slope and Pitch
In the percent slope mode the SmartTool allows you to read angles to meet requirements for sewer connections, ADA ramps, and grading. And showing compliance is merely a matter of pointing to the display. SmartTool also gives you roof pitch readings -- in inches of rise per foot of run -- right on the display. No two-handed measurements, no conversion calculations, and no mistakes.

Listen and Level Audio Feature
Have tasks where you really can't see the SmartTool but need instant feedback?  Then turn on the audio beeper.  When turned on with a single button, SmartTool lets you hear when your task is at level or plumb.  This can be great when shimming projects, leveling buildings, pool tables or other projects where you need immediate feedback but are not in a position to see the display. This can leave your hands free to adjust, nail, or screw the project in place when you hear the beep telling you it is where you want it.

Hold
The hold button makes it easy to measure in areas where the digital display is not visible.  Take the measurement, push the hold button, and then bring the SmartTool in front of you to see your reading.
