Question: What is the accuracy ??  For example if you were to measure a known distance of exactly 100 ft, what would be the error ??
Document: Met every expectation. Used once so far to measure POA roads. Very accurate--compared to known distance-- off by maybe an inch in about 100 ft. Measures well on rough asphalt/gravel surfaces. Mechanical counter far superior to electronic counters on other models (e.g. won't automatically shut off in the midst of measuring). You do have to be careful on resets. Often takes two &#34;presses&#34; to get all the dials way back to zero and lined up..
The 12" rollatape was easy to use from the start. Intutive, light weight and easy to handle. I used it to measure the distance I walked in the Ilahee perserve and was astounded to find that I walking between 3.5 and 4.2 miles.Great product.
Solid product. Does exactly what I need it to do. I would recommend it for any surveyors like myself who need measurements all the time.
This product is solidly built except for the internal mechanism. It worked well for the first couple months, then the counter mechanism started to jam and I would hear grinding when rolling the wheel. It was impossible to reset the count to zero when this happened. Or, it would fail to measure while rolling. I wound up taking it apart on more than one occasion to find that the plastic parts on the counter dials were stuck together. I released the internal parts by hand, put it back together, and it would work for another week at a time.
Was within a few inches in approximately one hundred feet on a smooth surface.One aspect that requires adjustment is the height of the wheel. If you're measuring from a wall, the distance from the axle to the ground needs to be taken into account. Plus it helps to read without lifting, because the wheel can rotate slightly.All in all, works as anticipated, and have set aside the old four inch wheel.TriFlow is an excellent lubricant. Reset mechanism works fine. See no reason why this unit shouldn't continue to perform well with reasonable care.The smaller unit was more compact and could be carried inside a tool bag, whereas this one has to be carried separately, but would not go back due to the ease of measuring larger distances.
So far, a great wheel for the price. Like any other, you cannot run with it on rough terrain in order to maintain accuracy. Is well built, and sturdy.
This measuring wheel does an adequate. I wish that I had spent a bit more money so that the distance could be reset at the handle rather than bending over and resetting.
Very easy to use. Just walk and measure. Remember it only goes to 10000 feet and then reset to continue to use it.
I needed this to measure lengths of trails that I build on property and it works great and is accurate
Having read reviews about a delicate internal mechanism, the first thing was to disassemble and spray liberally with TriFlow. Took a bit more than I expected to reassemble it. There are two plastic end pieces that hold the axle. After that, all good.Had been using a four inch wheel for measuring commercial roofs, and for larger buildings it was very accurate but just too slow. Could take many hours, especially with aggregate (rock) surfacing.The larger wheel is much quicker and sufficiently accurate. It doesn't seem to give the same accuracy down to the inch, but very close.Had someone on the roof with a measuring tape and we checked accuracy.
Answer: yes
