iGaging 6" Digital Outside Caliper

I purchased the iGaging Digital Inside Caliper with Friction Join and Tension Adjustment to handle specialized internal woodworking and machining measurements, and it has been absolute perfection. The build quality is top-tier; the heavy-duty legs are rigid and perfectly machined, completely avoiding the flexing issues that plague cheap plastic alternative gauges. The standout mechanical feature is the smooth friction joint combined with a reliable spring-load movement. It allows you to glide the calipers open seamlessly inside recesses or deep grooves, holding its exact position via tension until you lock it down firmly using the integrated thumbscrew knob. The digital performance is incredibly accurate and highly versatile for a wide range of shop tasks. Long battery life. The extra-large LCD screen is highly readable, and the top control button allows you to effortlessly cycle through three distinct readout modes: decimal inches, metric millimeters, and fractional inches down to 1/64-inch resolution. It also includes an essential "Hold" function that locks the measurement on the display screen. This means you can comfortably extract the calipers from tight, hidden bores without worrying about accidentally shifting the legs and losing your reading. For anyone processing deep parallel recesses, turned bowls, or internal diameters, this direct-reading caliper is a phenomenal, 5-star value.

Makes things a lot easier coming up with measurements

Ever wanted to know the thickness of glass used for a fish tank? This is your key to the answer! Fish tanks often have trim that keeps you from using a standard caliper on it. But with this, I can measure the glass without bothering with the trim. My only problem with it is that the measurements get so accurate, that it will change very quickly if there is ANY angle to the tool what so ever, while trying to measure. So 11/16th's may turn into 23/32nd's with the tiniest least-noticeable twist of the tool. And glass is often measured in "standard" sizes, even if they are off by a millimeter. So it's best to get to know the standards of thickness for what you are measuring so you can get it as close as possible to what you're reading.

I like it for $20. It is accurate enough as I gauged it against a slide caliper. I was concerned that it would not be accurate but it checked out fine at the 64th scale. The battery door would not stay closed right out of the package so I wired it in place with a wire tire from a bread bag. As I said with the 4 star rating. I am very happy for the price. If i was going to use the tool to help make money on at least an irregular basis I would consider the ones costing 10 to 20 times as much. In my case if I get to use it a few times over the rest of my life and it still works I won't complain much at all. Heck I got to use it once already. Jay

I have had this for several years. It still works flawlessly.
