I've been ghost hunting as a hobby for about two years now and I'm getting a bit frustrated with something. Every time I take my EMF meter into an old pub (especially 16th/17th century buildings with original wiring), I get wild readings - sometimes off the scale. My mates reckon it's just the ancient electrics, but it feels different somehow when it's actually paranormal.
Here's my process: I do a baseline reading before I start investigating. I check for obvious sources (phone towers, electrics, etc). Then I do a slow sweep of the building. In most cases, pubs have consistent high readings because they're packed with equipment - fridges, lights, the bar till systems. But there are pockets of really intense activity in certain areas. Cellar of the Bingley Arms in Yorkshire, for example - readings went mental near the old well.
My question: are other investigators filtering out pub environments because they're too noisy electromagnetically? Or is anyone else getting interesting results? And has anyone invested in better equipment that can distinguish between ambient electrical noise and actual paranormal electromagnetic signatures? My current meter was about £25 from Amazon and I know it's not precise.
