The D330i can connect to Android smartphones or tablets and PC's that are compatible with Bluetooth 2.1, including Windows 7 machines.

The D330i is not compatible with iOS devives.

In addition to the DISTO Transfer App for PC and Android, the D330i is compatible with the Leica DISTO Sketch App on Android devices.

The E7500i's Bluetooth data-sharing capability makes it the ideal hand-held laser distance meter for Building Information Modeling (BIM).

For more information on how Leica Geosystems supports BIM across our product line, check out the BIM Field Trip on our corporate site.

The compact D330i has a range of up to 330ft, depending on conditions.

That's right: A sixteenth of an inch. Take out a pair of earbuds. Look at how wide the the 1/8" jack is. Now divide that by half.

In Smart Horizontal mode, the D330i can determine the level horizontal distance to a target when you have to shoot over an obstacle. The onboard 360° tilt sensor provides an angle measurement so the software can do the math to figure out how much to subtract from the angled shot to get the actual horizontal distance.

The endpiece is an integral part of the tool, connected to the circuit board.

In the closed position the DISTO knows to measure from its base.

Flip it open 90 degrees to align the base perfectly on an edge or corner.

Flip it out all the way and you can put this baby in a corner to accurately measure diagonals. Otherwise, the width of the base would prevent you from getting aII the way into the corner, rendering the measurement inaccurate.

In Min/Max mode, you "sweep" the laser point into a corner. The longest measurement is recorded. Very useful for accurate diagonal room or window/door measurements.

In area mode, the DISTO determines the area of a rectangle or square in two shots. Volume mode adds a third vertical shot to calculate volume.

The simple area function is great when a room is a square or rectangle, but what if you have to determine the area of a room that has more than four corners? That is where the triangle function comes in. Divide the room into imaginary triangles, take three shots for each and then add them up. The DISTO will also tell you circumfrence and the angle of the triangle.

When the DISTO is in area or volume mode, you can use the add / subtract function to total up the area of several surfaces, or subtract an area, like a door for example, from a measurement.

Take indirect height and width measurements using the Pythagorean Theorem.

The key is to make sure your second shot -- the "rectangular shot" -- is perpendicular to the point you are measuring, shown as the 90° angle in the images. The best way to ensure accuracy is to use a tripod and an adapter.

The stake out function uses the continuous measurement mode to indicate where to place stakes along a stake-out line. Ideal for any situation where you need to place objects at a consistent interval. The display shows the distance to the next stake out point and the DISTO beeps as you approach it.

The D330i's internal memory stores the last 20 measurements for recall.

Set a timer to delay a measurement the same way you would with the shutter on a digital camera.

The Ingress Protection (IP) rating was developed by the European Committee for Electrotechnical Standardization (CENELEC) to create a standard of toughness.

The first number, in this case a 5 out of 6, is the rating for protection against dust. The second number, in this case a 4 out of 8, is the rating for protection against liquids.

See the Certifications page for detailed information about the IP standard.

The Leica DISTO™ D330i features wireless data transfer to older Bluetooth™ v2 devices. Its the way to break the #2 Ticonderoga pencil habit without having to replace perfectly good hardware.

The D330i is set up for a user who needs to capture precise, complex measurements in programs like AutoCAD in real time, primarily indoors.

Multi-tone beeps to confirm different kinds of measurements, active min-max tracking, dedicated buttons for the most popular features, and really great keypads (see below) make interior surveys a lot easier to do.

This is our pneumatic keypad torture chamber. It helps us quantify our quest for the perfect keypad and it puts suppliers on notice that we are big proponents of "trust but verify".

It is also a good example of how the experience of engineering and building a wide range of professional precision measurement tools translates to building a better laser distance meter.

Smart Horizontal: Math, meet World

Ever try to measure a room filled with people, furniture, or materials? All of those things tend to placed at a height that makes it hard to take a level horizontal shot with a DISTO, let alone run a tape on the floor.

Smart Horizontal lets you measure on-the-level when you don’t have a straight shot.

With Smart Horizontal activated, take your shot up to 45° over all the stuff in the way. The D330i uses a tilt sensor to calculate the difference between the length of angled shot and the same shot at 0°.

In the sample display, the D330i is pointed 33.6 degrees above level and measuring a slope distance to a wall 26.75 feet away. The actual level horizontal distance is 22.28 feet.

One button, no calculator. Easy, peasey.
