Starrett Cross Test Level and Plumb, Cast Iron, Satin Nickel Finish, Precision Tool for Machinery Setup, 3x0.5x0.5 Inches, 24-30 Minutes Accuracy - 134

I use this to level the head of a camera tripod for precise panoramic images. it is small and easy to use. Leveling in both directions usually takes 2 minutes but the results are always there if I take the time to dial it in with this level.

I mostly use this to level my high-end turntable, and it is a VAST improvement over the (round) bubble levels typically used. It is both easy to read and accurate. Bottom line is I can level my turntable in under a minute vs 5 minutes or more using other levels.Being two levels set 90 degrees from each other it is much easier to tell how much to adjust in each dimension compared to a bubble level. It is also generally easier to read each bubble than the Stabila level I use for construction - must be something about the size of the bubble and the shape of the vial. I find I don't have to squint or get additional light like I do with most other levels.As for accuracy, I checked it against a couple other levels I have in my shop on my dead-nuts flat table saw top. In every orientation the Starrett and Stabila agreed. I compared by setting them up in the same orientation, then reversing the Starrett 180 degrees. If there was any difference it would be doubled by the reversed orientation. I repeated by reversing the Stabila, again they agreed no matter the orientation.I have not yet encountered a bubble level that the manufacturer would guarantee was an accurate level - Starrett does in fact guarantee its accuracy as a level, although not to the extremely fine tolerances of their much more expensive machinist levels. And because of the length of the two legs are longer than the width of the typical bubble level it is much easier to make an accurate level (think about it: the distance representing one degree of error is much greater at 3 inches than 1 inch, so easier to detect and correct errors).By the way, don't be put off by the insert Starrett puts in the box that says that it is NOT guaranteed for use as a try square, as the other reviewer was - I have a certified try square and understand that making the levels accurate within the cross-test level does NOT imply that the tool has to be perfectly 90 degrees nor perfectly flat, and I do think they made the right choice in keeping the price down by not doing it (my certified square cost about half-again what this level did). Like the other reviewer I can get it to rock a little when I press one corner but looking at the level on my table saw top I can see that it is flat over the vast majority of its bottom, with a small gap at only one corner. Using it to level something it sits perfectly stable, and based on my tests and Starrett's guarantee I trust it to be level as long as I don't press down on that corner or ONLY support it by that one corner.BTW, leveling a turntable with a straight level is hampered by the fact that almost all relatively inexpensive ones have a magnetic strip on them, which makes them effectively useless with a turntable and terrifyingly dangerous near your precious kilobuck moving coil cartridge!

This Starrett level is an excellent tool for helping me with my model railroad building. Great quality and excellent performance.

Seem pretty expensive for level but it works be nice if they could bring price down

had to have..

Funny little tool which is really useful under the right circumstances. Starrett quality, i.e. first rate.

Quick tool to use on machinery bases prior to using the 98’s for precision work!

I use it every day at work , It sits on my workbench or in my pocket. it serves as a square and two levels at the same time.
