The User Manuals for the D3aBT/D330i can be found here. FAQ is here.

The Leica DISTO™ D3aBT (known in the US as the D330i) is a 9 measurement mode LDM accurate to 1/16th of an inch. It features a back-lit LCD display, a tilt sensor, and Bluetooth 2.1.

(Note: The D3aBT (D330i) does not work with iOS).

Pair the D3aBT (D330i) with a compatible Android device to run a variety of apps, including the free Leica DISTO™ Sketch App. Or Bluetooth measurements to your cursor in AutoCAD® or BricsCAD as you take them with the DISTO™ Transfer app.  

The D3aBT (D330i) is the ideal LDM for creating an as-built interior space in AutoCAD®. 

Getting as-built dimensions can be a challenge when there obstacles blocking the level horizontal shot you need to get the measurement you want to take.  In Smart Horizontal mode, the D3aBT (D330i) uses angle data from a tilt sensor and does the math to solve for the level horizontal distance to your target.

With a range of up to 330', a small wobble in the tool can translate to the laser point bouncing in wide arcs on your target . For best results when measuring long distances, keep your dot steady with a tripod and Leica's patented Fine Tune Adapter.
