Dividers are essential for the hand tool woodworker.  Used since ancient times, dividers are utilized by woodworkers for precise layout and measurement operations such as laying out dovetails, dividing a board into equal sections, precise transferring of dimensions from one place to another, scribing arcs and circles, and many more tasks.  

If you want the absolute finest dividers on the market today, then Starrett's American-made, 277 Spring Dividers with Round Legs and Solid Nut are for you.  These premium dividers are designed for craftsmen who appreciate and want a quality tool that will last a lifetime. These Starrett spring dividers have a finer adjustment and better balance than typical dividers so they provide a more sensitive "feel" for more precise operations.

If you are going to use my method of laying out dovetails (taught to me by Alan Peters) then I recommend using two dividers for laying out dovetails: one to mark the half pins and one to mark the full tails.
