- Millions of professional craftsmen worldwide rely on spirit levels from STABILA. Why is that? The "Spirit Levels Basics" videos clearly explain what makes STABILA spirit levels so unique. There are also helpful tips on what to look out for when buying a spirit level. Part 1 deals with the vial installation system and what you have to know about the subject of measuring accuracy. Also, the secret of the lasting precision of STABILA spirit levels is revealed.

When I bought my first Stabila level over 40 years ago, I was so confident in Stabila accuracy, but also protective of my first investment in such a precision instrument, that I did not deploy my new Stabila for daily jobsite use. Instead, I used it at the start of each workday to check and calibrate my older levels equipped with "adjustable vials." It did not take long for me to realize the practical value inherent in Stabila's motto, "Trust, never adjust." So I soon replaced all my levels with Stabila 96/196 series models, almost all of which are still in service yet today after decades of reliable use. I have also added many specialty models over the decades since, in particular, the various extendable models ranging from XTL to 80T to 106T. I have even customized some of my Stabilas to create models particularly useful in my specialty work installing millwork and doing renovations in historical structures where time has caused the basic structures and finished openings to deviate from level and plumb. I know of only one competitive level on the market today that can claim to equal Stabila accuracy, and none that can rival its incredible and time-tested durability. As craftsmen, layout tools are our eyes. My Stabilas enable me to see level and plumb with absolute certainty.
Thank you very much for your detailed feedback, which we really appreciate! 💛🖤
Thoroughly enjoyable video and the comments and answers below also added to my knowledge pool.
I'm just a DIYer, but I like to do things right. Looking to replace my old 'non' Stabila level and acquire a longer one at the same. Was pretty sure even before I arrived at your channel via your website (which doesn't appear of page 1 of a google search BTW, get you SEO sorted,😉😉) that it was Stabila level I wanted. This video made up my mind, that yup, I will be investing in one or two of your levels.
Gonna watch part 2 now and then likely will watch some product specific vids that you mentioned as well. Thank you.
We are very happy to hear that! Thank you very much and we wish you lots of fun with your new STABILA spirit levels 💛🖤
Question: What is meant by "upside down" level position: Does this refer only to whether the vial is in "reverse" position, or does it refer (also) to which edge of the level profile bears against the surface to be measured? To illustrate: In surveying the sill of a doorway, the vial would naturally be in the normal position with the edge of the profile farthest from the vial resting on the sill, thus providing the best accuracy (if the level specifies different accuracies for normal vs reverse vial positions). When surveying the head of the doorway, however, one could conceivably use the level with the vial itself in either normal or inverted position, depending upon which edge of the profile is used to make contact with the surface being surveyed. Can one presume that the machined top and bottom edges of the profile are perfectly parallel? If so, would a measurement taken with the vial in normal position (while using the top edge of the profile against the head of the doorway) have the same accuracy as the measurement taken at the sill, since the vial itself would be in "normal" position in both cases? Or should one always use the profile edge farthest from the vial as reference edge? Thank you for clarifying this detail.
Thank you for your question. So the spirit level should always be used with the measuring surface against the "object" to be measured - as you said, with the profile edge farthest from the vial as reference edge 💛🖤
@@STABILAOfficial If I may, I would like to ask a few follow-up questions: As a finish carpenter, almost all of my levels are Stabila 96, 196, or Tech series, and all but one of these are machined on both top and bottom edges. This fact has historically led me to believe that these edges are parallel and therefore that their relationship to the vial would be the same. This understanding seems further confirmed by the unusual fact that the accuracy of these levels is marked as identical in both normal or inverted positions (.029 deg.). Is my belief about parallelism correct, and if so, why is it better to use these levels as you instructed, i.e., with the edge farthest from the vial always as reference?
Also, I note that the only 196 series level I own that is not machined on both sides is a very old 59" model, on which neither edge is machined; instead, both edges are painted just the same as the rest of the profile. Investigating more closely, I also notice that this model does not have any marking as to accuracy whatsoever. So, is the additional production step of machining of both sides of modern iterations of this flagship series the key to its identical accuracy, regardless of position?
As somewhat of a Stabila fanboy, I am curious how the different Stabila series are named. Why 96, 80, 70, etc.? I thought that perhaps it had to do with the profile dimensions or extrusion die size or weight/length of the aluminum needed, but I haven't been able to discern it. Is there any relaionship between series names and profile characteristics?
I also note that all of my machined Stabilas are nearly perfectly identical in finished profile height, just a hair under 60 mm. Is this dimension so tightly controlled over time that for practical purposes on the job, for example in a case where one is using two 196 series levels in relation to one another, one can presume that every such level is identical in profile height? (I notice that my one odd painted level is about 1 mm taller than all the machined ones.)
Thank you for your replies to my curiosity. As a specialist in trim and door installations, my Stabila levels have been a major factor in my success over the years.
@@michael.schuler Depending on the type, STABILA spirit levels have either one or two measuring surfaces that you can use for measurements. So you are lucky the ones you have, have two measuring surface. With your first question, I thought you were referring to one of our most common spirit levels (type 70), which only has one measuring surface. But also the number of measuring surfaces on your spirit level is indicated on our website in the technical data on the product pages for your model - if you get a new one and are not sure👌
The accuracy of the spirit level is marked on the profile. A distinction is made between the accuracy in the normal position (normally 0.5 mm/m) and that in the reverse position (0.5 mm/m, 0.75 mm/m or 1.0 mm/m depending on version). You can also view the accuracy values for all spirit level models on our website on the product pages.
You got us with the names (96, 80, 70 etc.) - they have no meaning whatsoever 🙈
@@STABILAOfficial HELLO! I follow this discussion because I am about to buy a 80as set but I have a question about this....if I put the level on the middle of a wall in regular position and I have to draw an horizontal line...if I use the top part to mark...then the line would be 0.75mm/m ? I mean only the bottom of the level is rectified with the bubble and gives 0.5 mm/m? I understand that if I use it upside down it gives 0.75 but if I use it regular position but use the top part to measure for ex. the bottom of a kictchen cabinet that is on my head...will I get 0.75 or 0.5? To sum it all up....using upside down and getting 0.75 is related to the bubble hitting the opposite part of the vial (less calibrated) or has to do with the fact that both sides of the level are not parallel like @michael.schuler was saying ??the 80as says "two measuring surfaces" ..but are they both 0.5mm/m if the level is used in regular position?? I hope you can understand what I mean ...thank you for the support!
@xx-og1sg Thank you! You asked the follow-up question that I too wanted to ask.
