Hi Quy,
Reduced to Magnetic Equator is generally used in areas of low magnetic latitudes. Please have a look at the Application notes in the help for Reduce to Magnetic Equator and Pole for more information:

It's my understanding that you can use Reduce to Magnetic Pole for low latitudes, you would simply increase the Amplitude Correction the closer you get to the equator. However, this could result in artefacts perpendicular to your declination, or under-correcting the amplitudes of features along the declination direction. There's not often a single solution, you may want to try both Reduce to Magnetic Pole and Equator and compare the results.0
