• 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Two Point Pythagoras

    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.

  •  

     

    "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.

  • Stake Out Function

    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.

  • 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.

  • 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.

  • 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 aII the way into the corner, rendering the measurement inaccurate.

  • 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.

  • Store measurements and images with measurements associated with them.

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

  • "IP" stands for Ingress Protection. 

    The Ingress Protection (IP) rating was developed by the European Committee for Electrotechnical Standardization (CENELEC) to create a standard of toughness for electronic devices: Higher numbers mean more resistance to dust and water.

    For more information on IP ratings, see the IP section on the Certification page.

The Leica DISTO™ E7400x is a 9 measurement mode LDM ​ intended for use on active job sites. It features a precise laser module, a backlit LCD display, a tilt sensor, and a ruggedized chassis. 

The E7400x is rated IP65 -- totally protected from dust and low pressure water contact. The E7400x also has a 2 meter (~6') drop rating.

Measuring the diagonal distance of rough openings can be a challenge. It requires bending a tape just so to get both ends all the way into the corners, and the bigger the opening the harder it is to do that without having the tape collapse on you. The E7400x eliminates the hassle and makes it easy to get accurate diagonals using its intelligent end piece and a min/max mode.

There are often obstacles blocking the shot you need to get the measurement you want on an active job site.  Smart Horizontal solves that problem by letting you shoot over obstacles to determine the level horizontal distance to your target. The tilt sensor automatically calculates the difference in length between the longer shot you take to clear obstacles and the horizontal line you need to get your measurement.

With a range of up to 395', 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.

ToolSelect Review of the DISTO E7400x

ToolSelect.com may be gone, but all of their tool reviews still live on the ToolSelect YouTube channel.

Here, Barnaby asked Chad Klompstra from Bruce Heys Builders to review the E7400x.

How to use the E7400x

Some of videos refer to the X310, which is the European model number for the E7400x.
