Robust, Smart, and Multi-functional

Reinforced Housing

The precision measurement module and elements are protected by solid rubber and fiberglass reinforced housing.

The Leica DISTO E7400X is therefore shock-resistant and passes drop tests from up to 6ft height.

Tough IP65 Protection

The Disto E7400x is protected against water, dust and shock with a IP65 protection class rating.


To obtain an IP65 rating, the case must be tight enough to provide complete protection from dust entering any of the electronic components.


It also can sustain water projected by nozzle against the enclosure from any direction without harmful effects after 3 minutes of continuous spraying.

Smart Indirect Measurements

Thanks to the combination of distance and tilt measurements, you can determine the horizontal distance precisely - even over obstructions. With the help of the tilt sensor, you can also determine indirect heights.

This function is very helpful if walls, hedges or people are between the instrument and the target.

Min Max Measurement
Minimum/Maximum Measurement
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.
Area and Volume
Area & Volume Measurement
To get the area of a ceiling, floor, wall, or the volume of a room, you only need two or three measurements. No need to write down the individual values! The precise result is calculated automatically and shown on the display.
Digital Point Finder
Digital Point Finder
The integrated digital Point-Finder, with a 4x zoom and color display, makes finding the target at long distances a breeze. Its high resolution capability provides a sharp, crystal-clear image, allowing measurements to be taken even in glaring sunshine.
Triangle Function
Room Angle / Triangle
The triangle function helps you to calculate, quickly and efficiently, the area of a multi-cornered room. Divide the room into imaginary triangles. Using only three measurements, determine the area of each triangle, which you can add up cumulatively. Pressing a key gives you a detailed display of the room angle, so that you can quickly check whether it is a right angle.
Painter Function
With this function you can determine the total wall area of a room without having to note down any intermediate results. Simply measure the lengths of the walls which you can add or subtract as required. Finally measure the room height, which is then automatically multiplied by the previously calculated value. 
Pythagoras Function
Using the tripod, you can measure distances indirectly, horizontally and vertically.The Leica DISTO calculates the result automatically for you from three measurements. Functions such as automatic minimum and maximum measurements help you to measure the right point.

Partial heights, e.g. balcony or window heights, are determined by Pythagoras. Pythagoras Functions
Tilt Sensor
360° Tilt Sensor
The tilt sensors in the Leica DISTO can measure inclinations up to +45°, or even have a measurement range of 360°. This means you can measure inclinations over your head. This is particularly useful for determining roof slopes. 
Tilt Sensor
Smart Horizontal Mode
Smart Horizontal Mode
The desired horizontal distance is determined using the tilt measurement, event if the object cannot be directly targeted horizontally. This is very helpful if there are obstacles, e.g. walls, hedges or people, between the instrument and the target.
Smart Horizontal Mode
Height Tracking
Height Tracking
You can determine the heights of buildings or trees that have no suitable reflective points by using the height tracking function. Target with the digital point finder on the bottom point of the height to be measured and take a measurement. Then target with the laser on the top point of the object. The display then shows the height.
Height Tracking
Stake Out Functions
Stake Out
One or two different distances (a and b) can be entered into the device and then used to subtract from defined measured lengths. The display always shows the current stake-out distance and a direction arrow. At a distance of 0.1m to the next stake-out point an acoustic signal sounds.
Stake Out
Add Subtract Measurements Function
Add and Subtract Measurements
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.
Set a timer to delay a measurement the same way you would with the shutter on a digital camera.
Multi-Function End Piece
Multi-Function End Piece
Whether measuring out of corners, slots or from edges, with this end-piece you are prepared for all measuring situations. The instrument detects the end-piece automatically, which helps you avoid expensive measuring errors.
