Green backlight for easy reading in the dark.
Hidden magnetic bottom
Magnets hidden make sure it's reliable for measuring meral surface and also avoiding the influence of absorbed metal dust for the accuracy.
Inaccurate display warning
When the device tilts diagonally over 30 degrees, it will display ERRO instead of an angle. Because in this situation, this angle gauge is not accurate as it shuold be.
Frequently Asked Questions
1. Why it always show ERROR or ----(no readings)?
MEMS technology provides precise measuring result, but it will not accurate when angle gauge tilts diagonally over 30 degrees. So it tells ERROR or ---- to remind people to use it in a accurate way. Angle gauge with no ERROR indication will not give a correct measurement.
2. Do I need to recalibrate this angle gauge? How to recalibrate it?
GemRed angle gauges are well-calibrated from our factory and lab. You can use it out-of-box. If you want to recalibrate it, please refer to the video in the product page.
3. Does it has magnets on all four sides?
It only has magnets on the bottom. This angle gauge only work with the bottom. Other sides will not give accurate measurement.
4. What's the return policy for this angle gauge?
GemRed provides life-time after-sales services for its products.

I’m a retired shop teacher, years ago I bought one of these from a major supplier for setting the table saw blade angle at school as my students seemed to struggle and got sick of me giving them my “there is no such thing as good enough†lectures! Anyway I finally took a chance on this one as it was cheap enough and it works as good as the much more expensive one I bought years ago. Very happy with this purchase. Makes mitered corners for boxes super easy 44.5* spot on!

I got this to make sure my table saw, miter saw, jointer were square. While it is one of many ways to check angles, it is convenient and accurate.

I purchased this to ensure my table saw blade was square to my table - it works well but it is sensitive and tends to jump back and forth - so one needs to take a reading and wait, the adjust, take reading etc.. overall a good product and worth the small investment.

This is amazing. You set it on your table saw to "zero" it out, and then attach it to your saw blade (magnetically) to get the perfect degree for your cut. This really improved my game. I never adjust my saw blade without it.

Great product. $10 less than the one I got at Harbor Freight and 100 times better. And free shipping with Prime. Showed up the day after I ordered it. Measures absolute angles so it works great as a level. But also does relative angles. Easy to read inside or outside, even in direct sunlight. Or in the dark with the backlight. The backlight turns off after a short time to save battery life but the display stays active. Moving it makes the backlight pop back on.Accuracy is exactly as advertised. About +- .2 degrees. Better than a bubble level. If I measure an angle of a surface and it shows 0.8 deg. I can then flip it around to all 3 other sides, and see numbers like 89.2, 89.4, 0.7. Or rotate it 180 to measure the same angle from the other side, and the number is normally +- 0.1 or the same value.There are two arrows that point up and down to indicate which direction is the zero angle.When you turn it upside down to measure an angle from below, the numbers display inverted to make it easy to read.The base is magnetic, but not the sides. Easy to attach to something like a framing square to make it a long reaching level.And it comes with a belt pouch and battery!I couldn't be happier. Perfect simple tool. Doesn't add extra buttons to make it look "better", or lie about its accuracy by displaying extra zeros to get people to buy it. Don't waste your money on those. This is the angle finder and electronic level you are looking for.

It does what it is supposed too. And paired up against my original one, it reads correctly. I have had no issues with it other than having to change the battery in it not too long after starting to use it. I replaced it with a similar low cost battery and it's doing just fine.

Easiest way to hit an angle on a table saw. I should have bought one a long time ago.

If you zero this out on a level surface, then rotate 90 degrees on its side, the gauge is off by .1. That doesn’t affect the bottom reference surface, but I’d expect the case to be square at least.Overall It’s accurate enough for most uses, but for cutting irregular miters you really need accuracy down to 100th of a degree, as it is it’s hard to tell if the gauge rounds up or down a tenth of a degree.The packaging was protective and the nylon pouch is a nice bonus for storage.
