Do People Do Research Before Purchasing Paranormal Investigation Equipment?

I can't speak for everyone, but it seems that there are people out there doing paranormal investigations that buy equipment just because it was seen on tv, the newest thing out or its something they think may help them on investigations. There are a lot of companies out there that mis-advertise things, say its one thing when just doing some research will show that it's clearly not, re-brand an item and sell it for more because its "for paranormal investigating" oh and by the way, its illegal to re-brand something that's already re-branded or slap the word ghost in front of it and claim its for paranormal investigating.

Yes I own an online paranormal equipment company, but I am not writing this so people will buy from me and not the other guys. I am writing this as a paranormal investigator myself and am tired of seeing people get ripped off. To many paranormal equipment companies are using the tv ghost hunting shows to sell there items. It doesn't matter if there's a better item, or less expensive item just like it out there, if the "pro ghost hunters on tv" use it, it must be good, or if the word ghost is put in front of the item, hell it must be something special and will attract spirits, lol.

99% of paranormal investigators don't charge to investigate a home, piece of property or building, so why wouldn't they do a little research on the equipment they are interested in and not just buy something caused they saw it on tv or there is the word ghost in front of the name?

I don't know maybe its just me, but before spending $100's of my hard earned money, I want to do as much research on the equipment I'm looking into. And actually purchase something that will be useful.  I understand that we know nothing about the paranormal and yes it may be a tool made for something besides paranormal investigating that catches the best evidence yet. All I'm saying is, just know a little about what your purchasing first, I mean you wouldn't purchase a tv without doing some research on brands, different things it can do or accessories, all I'm saying is treat your paranormal equipment purchase the same way.
