Leica : DISTO™ D510
Bluetooth Smart (4.0)  
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. 
Single Measurement 660ft Range  
The big receiver lens and the module it is connected to can see a laser dot outside at distances of over 600 ft, depending on conditions. 
Area / Volume  
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. 
Min / Max Function  
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. 
Smart Horizontal™ Mode  
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. 
Triangle / Room  
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. 
Trapezium Function  
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. 
Pythagoras Function  
Take indirect height and width measurements using the Pythagorean Theorem.
Three Point Pythagoras
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. 
Painter Function  
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. 
Sloped Object Measurement  
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. 
Height Tracking  
"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 
Height Profile Tracking  
Measure slopes with multiple shots. Each shot is stored as a profile pair that references the step before it. 
Stake Out Function  
The stake out function uses the continuous measurement mode to indicate where to place stakes along a stakeout 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. 
4x Zoom Pointfinder camera  
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. 
360° Tilt Sensor  
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. 
Memory stores 30 Displays  
Store measurements and images with measurements associated with them. 
Add & Subtract  
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.

Intelligent Endpiece  
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. 
Timer  
Set a timer to delay a measurement the same way you would with the shutter on a digital camera. 
Personalize Favorites  
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 mostused functions on the tabs at the bottom of the touch screen.
