Is anyone else's EMF meter just absolute rubbish in the rain?

Right, I've invested about £200 in what's supposedly a decent EMF detector - the SB7 Spirit Box knockoff from that site everyone recommends - and I took it out to Pendle Hill last weekend for a proper investigation. Conditions were ideal, bit overcast, temperature stable, the works. Then about halfway through the night it absolutely bucketed down and the thing started going mental. Couldn't get a clean reading to save my life.

Now I'm wondering if I'm just an idiot who didn't waterproof it properly, or if these gadgets genuinely can't handle British weather. Has anyone else had this issue? Should I be wrapping everything in cling film like I'm prepping for a trip to Narnia, or am I better off just waiting for a dry night?

Genuinely asking - don't want to waste another evening out on the moors if the equipment's gonna have a breakdown the moment a cloud sneezes at it.

Mate, the issue is that most of these meters aren't designed for actual British conditions. Manufacturers test them in Arizona or whatever. Get yourself some decent dry bags - the ones rock climbers use - and double-check all your batteries aren't corroding. Also, avoid using them during electrical storms obviously, but normal rain shouldn't kill a properly sealed unit.

The SB7 knockoff is honestly your problem there. If you're going to drop £200, get the actual ITC-Z or save a bit more for the legitimate SB7. I learned this the hard way after three "investigations" that were actually just me standing in the rain swearing at a broken meter.

This is why I stick to thermal imaging cameras and digital recorders. Less to go wrong with moving parts, and they work fine when wet. Plus you get actual evidence you can review later instead of just a number that goes beep.

Has anyone else had this issue?

Absolutely. Pendle Hill's a nightmare anyway - too many geological anomalies. You're probably picking up naturally occurring electromagnetic activity from mineral deposits, not anything paranormal. But yeah, waterproofing helps either way.
