I bought this Neoteck digital dial indicator on February 17, 2018, mainly to help calibrate my table saw. More than eight years later, it still works nearly as well as it did when I bought it. I have replaced the battery only once, and that was fairly recent.
My table saw setup was basic. I screwed the indicator onto a piece of wood and attached a small angle bracket to the mounting point on the back. This made a homemade jig that I could run along the saw’s guide while keeping the indicator against the fence.
I would place the indicator against the fence and zero the display. As I moved the jig along the fence, the reading showed how much its position changed. Positive and negative readings indicated the direction and amount of the difference, allowing me to adjust the fence in or out. It was a practical way to check alignment instead of relying on sight alone.
The indicator has three controls: zero, on/off, and a button that switches between inches and millimeters. The zero function establishes a reference point wherever the probe is positioned. The display then shows the change as the probe moves.
Getting the probe to rest on exactly zero during my handheld demonstration was difficult because my hand was moving. After I pressed and released the probe, the display returned to within 0.0005 inch of zero. That is the smallest displayed increment in inch mode, so it was close enough for this demonstration. I would still use a stable mount for an actual alignment check.
According to the supplied seller listing, the indicator has a measuring range of 0 to 25.4 millimeters, or 0 to 1 inch. The listed resolution is 0.01 millimeter or 0.0005 inch. These are seller specifications, not measurements I independently verified. The listing also says the indicator uses an LR44 battery and includes a removable rear cover with a 6.5-millimeter mounting hole.
One limitation of my setup is the small mounting point on the back of the indicator. The angle bracket worked for my homemade table saw jig, but anyone building a similar fixture will need to plan how the indicator will attach to it.
The main reason I still recommend this indicator is its longevity. I have owned the same unit since 2018, used it for table saw alignment, and replaced the battery once. It remains easy to operate and continues to provide useful readings when I need to check small relative changes in a workshop setup.
