We have some trifield units, the standard and the natural DC field units. Latest one is a digital readout has a nice clicking sounds that speeds up it the field gets stronger. Have to say I like this unit, I was in a reported "haunted room" recently and I got some great info form it. It's good for relative measurments, i.e reading 16 compared to reading of 36. I find that on TAPs and other ghost hunting shows that a lot of the equipment poeple never talk in proper units WRT the firlds as this would a least give us an idea of the work that could be done under the influence of an electro---magnetic field.
We have taken some interesting reading from the Trifield Natural one though, as it its alam has gone off when a "gifted" person was experienceing something ( i could see nothing, but at least the EMF reader went off!)
It's my favourite part of investigations TBH, getting a increase in electro magnetic fields, for that reason i have far to many meters, and I hate those bloody call sensor ones with the little red lights and the crazy beeping and the little lead hanging out of them. Every paranormal investigation group that appears on "A Haunting" use them, I think they just have one kit that they share on that film set.
anyway thats my rant over and done with.
