The persistent precessing domain (PPD) is an isolated region of coherent spin precession which is observed in the B phase of superfluid He-3 at the lowest achievable temperatures. It has many unusual properties and its free decay can exceed 1000 s at the lowest temperatures. Previous observations of the PPD were highly irreproducible but we now find the PPD to be very reproducible when there is a field minimum along the cell axis. Here we discuss measurements of the PPD as we control the magnetic field profile, allowing the depth of the minimum to be adjusted.
