Functions that need to know the angle of the DISTO™ when the shot is taken are enabled by a highly accurate 360° tilt sensor that determines the angle of the laser. These include Smart Horizontal and Height Tracking modes.

The onboard digital camera features a 4x digital zoom "point finder" that shows you where the dot is even if you can't see it with the naked eye. Put the crosshairs on the spot you are measuring to and hit the button. It's that simple.

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.

It's not always so simple as taking one shot to get the measurement you need. Sometimes its handy to add multiple shots together, or subtract a negative space from a measurement.

As you use the Add/Subtract function, the final result is displayed in the main line, and the last measurement taken is shown above.

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.

Send measurements directly to your apps using Bluetooth Smart.

See our App Directory for a list of apps that all kinds of professionals are using to transform the way they work.

See our blog for more information about device compatibility.

The Leica DISTO™ Plan App lets you take a picture with your iPhone or Android and layer measured lines on top of it.

Bluetooth DISTOs & the wifi 3D Disto are useful for Building Information Modeling (BIM).

The D810 touch is like that big Swiss Army knife you always wanted, the one with all the doodads.

The compass is useful for answering questions like, "Wait. Is this the north elevation or the west elevation?" or "Which way am I facing?"

The Diameter function uses Measure in Picture technology to determine the diameter of cylindrical objects, like tanks.

The read out also provides circumfrence (top number) and circular area.

The dual lense digital camera employs a wide field lens and a 4x zoom lens to power Measure in a Picture (MIP) technology -- the most advanced handheld remote measurement technology currently available.

Combined with the data returned by the laser and the tilt sensor, the software uses the fixed focal lengths of the lenses to determine height, width, and area in MIP mode or the circumference and volume in Measure a Cylinder mode.

The unit stores images with measurements laid over them for recall on the device or to download later, an especially useful feature for as-built measuring or Building Information Modeling (BIM).

Measure slopes with multiple shots. Each shot is stored as a profile pair that references the step before it.

"Real time" height tracking for situations where you can hit a reflective target (like the ground) on the low end, but not at the top. Perfect for measuring the height of an overhead wire, for example.

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 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 all the way into the corner, rendering the measurement inaccurate.

Store measurements and images with measurements associated with them.

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.

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.

With over 20 functions, chances are you are going to use one or two more than the rest. This Favorites function lets you bookmark your most-used functions on the tabs at the bottom of the touch screen.

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.

This DISTO™ will take approximately 4000 measurments per charge. The 3D Disto will typically last a full working day of 8 hours.

Indirect distance measuring between two points. The reported measurements also include the horizontal distance between the two points, the vertical distance between the two points, and the angle between the points.

Use Smart Horizontal to 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 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.

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

The Trapezium Function is useful for determining the length and slope of a roof section, and the area it covers. The DISTO™ uses the its internal tilt sensor to calculate the angle and the distance between the shots, which means you can measure roofs accurately from the ground.

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.
