I fancy myself a bit of a handyman and prefer to do the vast majority of home repairs myself. Many projects require the use of a tape measure.

While I generally get my measurements right, occasionally I read the markings wrong, or the length is so great it’s difficult to measure with one person. These missteps often lead to me having to redo work and/or the utterance of four letter words Julie probably wouldn’t appreciate me listing.

Apparently, the gods of home repair felt sorry for me and granted me the opportunity to review the Jetery digital laser rangefinder. Hopefully, this will allow me to make accurate measurements, saving me time and swear-jar money.

The Jetery is a handheld rangefinder that measures 4.65 x 2.13 x 1.10 inches; it’s basically the size of a bulky TV remote control. It weighs 129 grams, again about the same as a remote control.


The front of the rangefinder contains everything you need to use it. The top half of the rangefinder contains the LCD display, while the bottom contains all your function buttons.


The top left of the device also contains a small, horizontal bubble. This is used to make sure you’re holding the rangefinder level during most operations. As you can see in the picture, my dining room table is nowhere near level.

The rear of the rangefinder has the battery compartment, a threaded inlet for use with a tripod, and laser information.

The device is powered by two included AAA batteries.


The front of the device holds the laser and the receiving window.

Also included is a nylon case which can be attached to your belt,


and a hand strap to help protect you from dropping the device.


The rangefinder is extremely easy to use. First, you turn the device on by quickly press the “meas” button.


Once you do that, the display will light up and appear as above.

Once the device is on, it enters single measurement mode. To use this mode, you first activate the laser beam by pressing the “meas” button once.


Once the laser beam is on, it projects a red dot onto your target.

You then press the “meas” button again and the device will measure the distance to the target.

Measurements can be displayed in the six formats shown above.

Along with single measurement mode, the rangefinder can be placed into continuous measurement mode. As the name suggests, continuous mode provides a constantly updated length as you move the device.

To enter continuous mode, you long press the “meas” button until you see “max” and “min” appear on screen.


The screen lists three lengths in continuous mode. The top length is the maximum detected length, the middle is the minimum detected length, and the bottom is the current detected length.

Along with standard measurements, the Jetery can also determine a rooms area and volume.

To determine area, you press the cube button under the “meas” button.


The display will then appear as above.

You then measure the length of the room, followed by the width. The device will automatically calculate the area and display it at the bottom.

To measure volume, you double press the cube button.

You then measure length, width, and height; the volume is then displayed at the bottom of the screen.

Not only can the device calculate area and volume, but it can also use Pythagorean theorem to calculate distances.

For instance, if you needed to measure the height of a wall, but were unable to get close enough to measure it, you could use this feature.

To do so, you press the triangle button to the right of the “meas” button.

You then measure the hypotenuse of the triangle. In the example above, the hypotenuse would be the 45 degree angle from the floor to the top of the wall you want the measurement of.

Next, you measure the length of the floor from your location to the wall you want to measure. The device will then display height of the wall at the bottom of the screen.

This feature can also be used to measure the hypotenuse or segments of a wall.

The Jetery can also add and subtract distances.

To use the addition feature, you press the plus sign on the device.


You then take two measurements and the device displays the sum of the two at the bottom.

To use the subtraction feature, you press the minus sign on the device.


You then make two measurements and the device displays the difference at the bottom.

Finally, the Jetery can be used to save measurements; this is a very simple thing to do.


After making a measurement, you hold down the save button for three seconds. This will then display a number in the top left of the screen – in this case “001”.

To scroll through saved measurements, you press the save button once and then use the plus and minus buttons to scroll.

The measurements aren’t saved permanently; each time you turn off the device they are forgotten.


I wanted to compare the accuracy of the Jetery to a standard tape measure.

First, I measured the width of my foyer.

According to the tape measure, the width measured 95 1/4 inches. The Jetery found the width to be 95 3/8 inches.

The measurements were an eighth of an inch apart, but that could be the result of me not measuring the exact same portion of the room.

I then measured the length of my son’s air hockey table. This time, both the tape measure and Jetery produced the exact same result, 47 1/16 inches.

It seems the device is extremely accurate.


I loved the Jetery and plan to use it a lot in the future. I no longer have to worry about misreading tick marks or waiting around for someone to hold a tape measure.

The device is extremely easy to use, but is capable of making pretty handy calculations. Not only that, but it appears to be very accurate.

If I were pressed to come up with a negative, I would say it would be better if the measurements were permanently store when saved; however, I didn’t really think that was too big of a deal.

Anyone that owns a home, or finds themselves making measurements often, should drop what they are doing and order this device immediately. I promise, it will save you time, energy, and headaches.
