New paranormal investigation kit—worth the money or overpriced rubbish?

So I'm thinking about getting into actual paranormal investigation (more than just reading forums obsessively) and there's this kit on Amazon for about £89.99 - comes with an EMF meter, digital thermometer, digital voice recorder, and some motion sensors. The reviews are mixed: some people love it, others say it's cheap rubbish that gives false positives constantly.

Has anyone actually used this sort of thing? More broadly, what equipment is actually worth investing in if you want to do proper investigations? I don't want to spend hundreds on professional-grade stuff if I'm just mucking about, but I also don't want equipment so dodgy it's useless.

Also, pro tip: if you're in the West Midlands, apparently there's a paranormal investigation group that meets monthly. I'm thinking of joining just to learn what I'm doing before buying gear.

GhostHunt_George: That kit is okay for starting out. The EMF meter is the weak point - it'll detect basically anything electronic and give you false positives like mad. But the thermometer and voice recorder are actually decent. For £90 it's not terrible. Just don't expect Hollywood results. Most of your time will be standing in the dark listening to old houses creaking.

"Most of your time will be standing in the dark listening to old houses creaking."

This is the most honest thing anyone will tell you. You buy the kit, you get excited, you spend three nights in an old pub in the cold, you record nothing of interest, and then it sits in a drawer. Not saying don't do it - I did it myself. Just manage your expectations.

Tech_Tim: If you're serious, get a decent digital recorder (£40-50) and a thermometer (£20). Skip the EMF meter for now because they're either cheap and useless or expensive and give false positives anyway. Honestly your mobile phone's voice recording is fine to start. Don't sink money into gear until you know you'll actually use it.

InvestigatorIan: Which West Midlands group? I'm near Coventry and I've been wanting to join one but didn't know where to start. Also, joining a group is definitely the right call. You'll learn more from three nights with experienced people than a year of solo investigations with expensive gear.

PracticalPete: The best equipment is honestly a camera that works in low light, a notebook, and a buddy. Seriously. Document everything, take photos, make notes of time and temperature. Most paranormal investigation is just careful observation anyway. The fancy kit is fun but not essential.
