Review: Amazing precision! - If you thought a good hardware store level was precise, think again. I needed this to level out the platen on my wide format printer, we’re talking about fractions of a mm tolerance that were causing the print carriage to rub. After using steel thickness gauges to level everything out, we were still getting a slight bit of blur across the travel. Bring in a $300 level I never knew I needed. First, you have to calibrate this yourself. Look up some videos and find a VERY stable table or just go straight to the concrete like I did, just make sure the floor is clean and there is no lose debris. Place some tape marks and take your time alternating directions. Once calibrated, you’ll be able to capture the slightest inaccuracies. 0.0002” per foot tolerance is no joke. We were able to plum up the platen in no time and fix the detail issue with the printer. Life saver! Would have never been able to achieve the same results using an ordinary level, not even close. It’s expensive for what it is, but everything about it is precision machined and the glass vial is insanely sensitive. The 12” version I purchased actually comes with 3 total levels. I knew it had an extra one on the front for a second axis, but it also has another for a 3rd axis located in the middle where the finger holes are. At this price and sensitivity, I wish it came with a case. It’s pretty robust and the main vial has a cover, but I’d like to give it some extra protection anyway.
Review: Very accurate - There are several great machinist tool manufacturers around, Starrett is one. This is a very accurate level.

## Features

- Adjustable - The vials are adjustable to a positive setting. It can be adjusted by turning the knurled knob on the side of the level, making it easy for quick leveling tasks.
- Durable Fine Finish - The base is made from cast iron and is precision-machined on the reference surface to increase durability. The vial is housed in a satin finished brass tube with a friction-fit closing cover to prevent breakage.
- Accurate and Precise - With the cross test vial, it is possible to simultaneously level in both directions. This prevents inaccuracies in the main vial reading caused by canting the level sidewise on round work.
- Ergonomic - The base of the levels features an involute groove between the bearing flats for accurate seating on round work. This groove has a special involute design, permitting better centering and greater capacity to handle larger rounds.
- The Standard for Excellence - Proudly made in the USA, Starrett combines over 140 years of American heritage and innovation with globally sourced materials to deliver exceptional quality tools and products.

## Questions & Answers

**Q: Is this a starrett exact level? meaning, made in china.**
A: This Starrett level is made in the United States.

**Q: Does the level come in the standard red Starett cardboard box?**
A: I don't know that it is the standard box.  It is cardboard and relatively well made.  The lid slips entirely over the lower part of the box.  The lid is colored red and says Starett a lot.

**Q: Does this level come with certs from starret?**
A: Depends on what you mean by "certs". There is a card that says "A bubble movement of 1 division (1/10") on main vial indicates an elevation of .005" per foot." The accuracy of this number is not specified - could be .004" or .006", no way to know. However, it is definitely very sensitive - more than is useful for most purposes. There is a screw to adjust the vial so that it is level - turn the assembly around on a flat and "level" surface, and the indication should be the same in both directions, or adjust the screw so that it is the same, and then it will be accurately reading the tilt of the surface.

**Q: can i get a replacement bubble cylinder for the primary bubble**
A: There are 2 options that we have for replacing the bubble cylinder's. 1 option is replacing the vial w/ solution only but you must know how to install it properly or option 2 would be to purchase the tube and plug vial that is already set properly inside the silver casing.

### ⭐⭐⭐⭐⭐ Very accurate

### ⭐⭐⭐⭐⭐ World's Greatest Level
*by J***E on July 10, 2014*

I was amazed of the accuracy of a machinists type of level vs a good carpenters level. No comparison, and Starrett, as anyone knows has a reputation that is second to none. When I borrowed my brother's Starrett 8" machinist level, and used it to level my pool table, it truly did the job so well, that it's almost like magic, seeing how straight the balls could actually roll, and even when hit slow, they continue on their straight path with no variation at all of getting off course. I had been trying to get one of these for over a year on e-bay, but gosh, the prices were always over $100.00 even for those that could have been taken better care of. I finally decided to pay a little more and just get a new one. It will easily hold its value by taking care of it, and in 30 years time, will be worth more if not abused. Next project will be a plane, and needed something I could truly rely on to level the table with. It already made a believer out of me with how well it leveled my pool table. I use digital levelers on occasion, but trust this one more. And 100 years down the road to whomever inherits and still has this level, if they had taken care of it, it'll still be as good as the day I bought it. One can't say as much for electronic levels and will probably be lucky to get ten years use out of them. Their displays have a tendency to go out, and they are a bit finicky. It's nice when old fashioned technology trumps some of this new stuff. This is one such case.
