Klein Tools 935DAGL Digital Level Angle Finder with Programmable Angles, Measures 0 - 90 and 0 - 180 Degree or Dual Axis Bullseye Ranges

I got this handy little box to level my house, plus it turned out very useful for leveling the stones in an outdoor patio. This item is durable and simple to use. It automatically senses when you want it to run in 1D (traditional bubble level mode) or 2D (bullseye surface level mode). The mode depends on whether it's lying on its back or on its side.Its screen defaults to a vividly legible dark mode, which is a mercy when we work at night or in dark crawl spaces. Be sure to get the separate pipe strap if you need to level & plumb tubular objects.Note, there is in fact a 1D (bubble style) and 2D (surface style) level built into iPhones, and so I compared them. There was no context. The iPhone level is imprecise. As of July 2025, the iPhone level does not even pretend to distinguish inclinations in increments of less than one degree. That is practically useless for construction, especially in safety-conscious construction applications.This item is far better than the iPhone's built-in digital level, and it was well worth paying for the upgrade. This Klein level's precision is 1/10th of a degree in both dimensions. That is plenty for most applications. Extremely high precision engineering applications will need a high end Pro level 10x - 100x more expensive, but for household tasks and general construction, this level is perfect.As an added benefit over an iPhone level, there are none of the cybersecurity risks of leaving your phone (with its private data and high replacement price tag) lying around a worksite, plus this one is ruggedized and weather-resistant. There is a shock-resistant orange bumper around the edge. You can leave it on a surface for reference, or leave it strapped to a pipe, and it'll likely survive the shift unscathed.

Perfect little device. I got the 935DAGL on sale and don't regret the expense one bit.Some functions are automated, like tilt screen, tilt function change. I've yet to explore the alarm and memory functions but I don't really need those in my home garage. The included storage pouch is a bit too snug, and has no belt loop or clip, but it works for protection.

This thing works great !Can be used in many situations & the more you use it the more you realize new places it can be used. Leveling my trailer, leveling my tools on an uneven shop floor, etc. A very practical tool, worth the price & easy to use.

Amazing does all the angles!

Very good digital level. I use it now more than other levels. Game changer

It is perfect in every way. No flaws. But the smaller version of this is better. It just is. You'll use the smaller one more. This bigger version . . . there is nothing like it, but Electricians have little use for the horizontal level, but everything else is nice.

A little larger than I wanted but very accurate and functional.

Muy buen producto vino excelente funciona bien mide bien los grados
