Right, so Channel 4 screened a new documentary about Borley Rectory last Friday night and they used some kit I wasn't familiar with. It's called a 'trifield meter' - apparently measures electromagnetic fields in three dimensions? They got some absolutely mad readings in the chapel area - the thing was screaming constantly.
I've been ghost hunting for about eight years now and I've got a decent EMF meter (the K2 model, cost me about £80), but I've never seen readings spike that consistently. Either Borley's genuinely one of the most active locations in England, or those meters are picking up interference from the building's wiring. The doc didn't really address that possibility.
Has anyone here used a trifield meter? Are they worth the investment? They seem to run about £200-300 which is a fair chunk of change. Would love to know if they're more reliable than the standard EMF kit.
