We dont really use anything super hightech. You really dont need to.
Alls you really need is:
-Digital Camera
-Cam corder ( these are very nice to have)
- Tape recorder ( to get all of them nice EVP's) NOTE- Make sure that you have a EXTERNAL mic so you dont get any false positives.
- Flashlight ( really dont need to explain)
-Thermometer (Nothing special just the kind you can pick up at a walmart.)
-Spare batteries ( Never know when you will run out)
- And all of the little stuff (notepad,pen,ext.)
