Verifying Flux Density

I know the correct way to check the flux density for MPI is to use a hall effect meter but wondered how many people actually use one when working out in the field. And if not then how do people cover this in procedures, I know ISO 9934 says you can use other methods but doesn't offer any detail. I'm curious because in 7 years working in this industry I have never seen anyone use a field strength meter other than at training centres.
