| The SMARTTOOL has dozens of uses around the shop. Use for chassis setup, radius rod angles, bird cage timing, and fabrication projects. Features of the SMARTTOOL include a "hold" button which allows "freezing" and "unfreezing" readings which can be displayed as degrees, percentages (slope), or in./ft. (pitch) at the push of a button. Plus and minus signs indicate when the pitch is slightly more or less than the pitch shown on the display. Pitch readings are in 1/8 in./ft. increments. A listen and level audio feature emits an audible "beep" at level and plumb. An on/off switch will shut the tool off automatically if it's left idle for more than six minutes. Powered by a standard 9 volt battery.
