Packed with the most innovative measuring wheel features, it’s no surprise that the Calculated Industries 6575 Digiroller is regarded by many as the best measuring wheel on the market.

Don’t want the hassle of reading off analog displays? Then a digital measuring wheel is your best bet. More specifically, the Calculated Industries Digiroller Plus III. It just might be what you need in your tool kit.

Packed with the most innovative measuring wheel features, it’s no surprise that the Calculated Industries 6575 Digiroller is regarded by many as the best measuring wheel on the market. While it comes with a slightly heftier price tag than other models, the Digiroller Plus III is something that land surveyors and other professionals should definitely not leave home without.

The brand’s latest measuring wheel model as of this writing, the Digiroller Plus III completely embodies "form follows function." Boasting a 7-digit backlit display on its top-mounted control panel, it lets you easily read off measurements under broad daylight or even under low-light conditions.

As with most tools, however, this digital measuring wheel comes with a few minor imperfections. Other users found the position of the On/Clear buttons a tad inconvenient as it might cause them to accidentally reset the counter. It’s also unnoticeably heavier than its predecessor, the Digiroller Plus II, and more expensive than other measuring wheel brands.

Regardless, the Digiroller Plus III gives little to no cause for complaints; its handy features more than make up for its weight and price. Compared to the older Digiroller model (and other measuring wheels on the market), this Calculated Industries measuring wheel is designed with better ergonomics, accuracy, and efficiency in mind.

Features and Benefits

What sets the Digiroller Plus III apart from all other measuring wheels out there is its center-line design. This innovative design, combined with its heavy-duty 12.5-inch wheel, allows for improved balance and accuracy, ideal for getting distance estimations on rugged terrain outdoors.

Another thing that makes the Calculated Industries 6575 great for outdoor use is that it’s built to withstand tough field conditions. Featuring reinforced, shock-resistant metal construction and protective bumpers, this digital measuring wheel is heavily protected against the elements and is truly built to last.

True, this Calculated Industries measuring wheel comes with an incredibly sturdy build. But that doesn’t mean it isn’t easy to carry or maneuver. Its pistol grip rubber handle adds comfort to measuring distances all day long, while its foldable body and built-in carrying handle let you bring the measuring wheel wherever the job takes you—all without difficulty. Just fold it up, store it in its included carrying case, and you’re all set to go.

To add to its ergonomic design, this digital measuring wheel comes with large TruTac buttons that are pretty easy to press, even while you’re wearing thick winter gloves. Plus, its top-mounted control panel with a backlit LCD allows you to read off measurements or press buttons without having to bend down.

Prefer U.S. or metric units? Have the freedom of choice with the Digiroller Plus III. It can measure up to a whopping 9,999,999 feet, meters, yards, or inches with 99.5% accuracy, at a maximum speed of 12 miles per hour. A combination of efficiency and accuracy is what you’ll get when you have this digital measuring wheel at your disposal.

Safety Features

Since the Calculated Industries 6575 Digiroller is specially made for surveyors, landscapers, and other professionals, it features a design that can help prevent work-related hazards. One of its safety features is its high-visibility green color, which is bright enough to be seen in low-light conditions. Combine its hi-viz color with its reflective safety tape, and what you’ll have is the perfect measuring wheel to use near high-traffic areas.

Low visibility isn’t the only hazard found in workplaces. Ergonomic hazards are often overlooked by employers and employees alike, but Calculated Industries makes sure that its products are all ergonomically designed—just like the 6575 Digiroller. Its pistol grip handle helps prevent hand strains from working all day long, while its top-mounted controls eliminate the need to bend down, thus preventing neck and back strains.

Best Ways to Use the Product

Measuring distances, areas, volumes, and circles is easy when you use the Digiroller Plus III digital measuring wheel. Just place the wheel at the start of the measurement, clear the display, press the On/Clear button, and start rolling. Remember to keep the handle position consistent throughout the measurement.

When measuring areas and perimeters, roll the wheel along the length of the area being measured, then press the Length and On/Clear buttons. Next, roll the wheel along the width and press the Width/LxW button.

When measuring volumes, set the wheel to height mode by pressing the Set and +1/2 Wheel buttons. Then, roll the wheel along the height of the area being measured, then press the Set and On/Clear buttons. Next, use the wheel to measure the length of the area and press the Length and On/Clear buttons. After that, measure the width of the area, then press the Set and Width/LxW buttons.

Lastly, to measure circumferences, just roll the wheel along the area’s diameter and press the Length button.

Best Ways to Use the Digiroller Plus III

Like other measuring wheels, the 6575 Digiroller Plus III has a built-in kickstand, which you can flip down to keep the tool upright whenever you need to jot down measurements. But unlike others on the market, it comes with a cumulative memory key to save your data, so you don’t have to worry about losing your measurements. It also has a Units button, which allows you to change the unit of measurement of the displayed value.

Remember to follow the manufacturer’s care instructions when using, storing, or transporting the Digiroller Plus III digital measuring wheel. That way, you can keep it in pristine condition for years of use.

User Reviews

An average rating of 4.7 out of 5 can be considered fairly high, and the Digiroller Plus III well-deserves that. Measuring wheel veterans, among other users, found this model packed with quite the advanced features.

Apart from the many functions that this tool has in store, users particularly liked its overall design. Even users over 6-feet tall felt comfortable walking around with this measuring wheel, along with its ergonomic handle. They could attest to the fact that anyone who uses this measuring wheel—be they short or tall—will never find it unwieldy to maneuver.

Some reviews state that the top-mounted On/Clear button is placed in an awkward position. They say that you have to be extra careful to not press the button on accident.

Digiroller Plus III reviews
