Review on Accurately Measure Angles And Levels With GemRed XVB Digital Gauge Level Box For Pipe Conduit by Greg Cunningham

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.
