iGaging 6" Digital External Outside Caliper OD for Woodworking

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 ordered these calipers to measure various things but mostly for getting some outside measurements of various running shoes I have purchased. The calipers came in a one time use plastic package. Not any hard shell case to protect it against bumping and damaging. It does come with an extra CR2032 battery. The readout is LCD which is clear to read. The ON button also serves as the zero button. The left most button switches between millimeters and inches. I’ve had them for about 8 months now and I was a little surprised when I took them out to use them and the battery was already dead. Thankfully as I mentioned they came with an extra battery.

This seems to measure accurately. It uses two larger batteries rather than the small button cells in some similar digital caliper I looked at. The larger batteries are both good and bad - they are good for long battery life, not as good if you prefer a smaller calipier head.

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
