Most detectors have a standard size coil that comes with them, mostly an 11" coil. This is an all around coil. The other new coils are great coils and are used for tight areas and are a little smaller. They are also all around coils but used in different environments. The stock coil will cover more ground with each sweep. Every coil will preform a little different and Nokta has determined that the 11" is best served as the standard coil.
