A rugged laser distance meter for folks who get their hands dirty.
  • She’s short and skinny, but she’s strong: IP65 certified dust, water, and drop protection.
  • The E7400x knows when you are on the level…and it knows when you aren’t, which is how it measures heights and widths.
  • More accuracy and longer range than you are likely to need.

The E7400x has a range of 395ft, 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.

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.

In Smart Horizontal mode, the DISTO 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.

"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 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.

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.

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

Our IP 65-rated tools are the highest rated laser distance meters on the market. See the Certifications page for detailed information about the IP standard.

A hardened DISTO for rugged job sites.

The Leica DISTO e7400x strikes the right balance between simplicity and usefulness for an active job site.

If you are working mostly indoors on jobs like laying tile, framing out walls, or hanging cabinets you don’t need data-transfer or optics that are geared for planning and documentation: You need a tool that can get dirty and take a hit, day after day.

Measures distance and height

The Leica DISTO e7400x is simple and rugged, but it is far from stripped down. It calculates area and volume, has a “stake out” function that makes spacing anchors or studs equally a snap, and it has an integrated digital tilt sensor.

A laser distance meter with a bubble level on it is like a smartphone with a rotary dial. Using its tilt sensor and software the E7400x can calculate height and width and it can take indirect measurements.

Generally speaking, a Leica DISTO e7400x has a 390 foot range and is accurate to about 1/16 of an inch.

But Swiss engineers are not fans of generality.

DISTO laser modules are tested prior to assembly and complete DISTOs are tested before they are shipped. A certificate of accuracy is issued for each serial number and is included in the box.
