Advanced EMF investigation - what are your actual protocols and how are you ruling out mundane explanations?

I've been doing ghost hunting for a while now and I've noticed that a lot of investigations don't have rigorous controls for environmental EMF interference. People get excited about EMF spikes without considering wifi routers, electrical wiring, mobile phone towers, faulty appliances - basically all the things that generate electromagnetic fields constantly.

So I'm trying to develop a more systematic approach. Before any investigation, I'm doing background EMF baseline readings at various points in the location, checking for sources, noting weather conditions (which apparently affect EMF detection), and attempting to distinguish between sources.

The challenge: genuine anomalous EMF activity (if it exists) would presumably be inconsistent with environmental sources, show patterns suggesting intelligent interaction, and be repeatable. But how many investigations actually test for repeatability? Most people go once and assume any spikes they find are paranormal.

I'd love to hear about other people's protocols. Specifically:

- How are you establishing baseline readings?
- What counts as 'anomalous' in your investigation?
- Are you testing for environmental sources?
- What's your standard for declaring something genuinely unexplained?

Trying to do this properly rather than just waving EMF meters around like everyone else.

This is genuinely good practice. Most ghost hunters are absolute cowboys when it comes to methodology. They get an EMF reading near a house's electrical panel (which obviously generates fields) and declare it paranormal. Basic science controls would eliminate 90% of false positives.

I work in environmental research (different field but similar principles) and I'd suggest you start documenting your protocols in writing before each investigation. Baseline readings, environmental conditions, sources identified, duration of monitoring, sensitivity settings on your equipment, temperature and humidity. Turn it into a formal investigation log. Makes patterns much easier to identify afterwards.

For baseline readings I use a calibrated EMF meter (nothing fancy, about £60 from Amazon) and do a full walk-around documenting readings at different locations and heights. Takes about 20 mins but gives you context for anything you find later. I also note wall power routing because that's usually where anomalies cluster.

The thing about EMF meters is they're designed for occupational safety assessment, not ghost detection. So the thresholds that indicate 'electrical hazard' are way higher than paranormal investigators use. You're basically looking for needle movements that might not mean anything in their intended context.

Brilliant approach overall. If you're serious about this, you might want to add temperature monitoring with multiple sensors, pressure readings if you can access them, and audio baseline (because infrasound can cause emotional responses that people interpret as paranormal). Make it a full environmental profile. That's how actual paranormal research is done (as opposed to TV ghost hunting).
