EMF (Electro Magnetic Field) Detector: An emf detector is a must. It is easily explained by viewing ghosts as invisible energy. An emf detector will detect that energy. the same energy surrounding your computer monitor right now. If you get emf readings in a cemetary with no near by power lines, You got yourself a ghost.
Camera: Ghost hunting needs a camera #1 important item. I like digital, because here is no film, no developing, no over exposures, just digital results. A 35mm will also work fine.
Air Ion Counter: measures the amount of positive and negative ions in the area. Ghosts are said to give off electromagnetic discharge. So the positive ion count will read high
Baby Powder: Used to track ghost footsteps. I personally dont bring this ghost hunting
Barometer: when a barmometers pressure raises, its said ghosts are present
Candles and Matches: Backup Lighting Incase the flashlight dies. ghosts can suck your power right up.
Cell Phone: If a ghost attacks you or you need help while ghost hunting, grab your cell.
Batteries: Bring Extra’s Ghosts will drain the power fast. You dont want to get caught with a flashlight that dont work, or a useless camera.
Flashlights: Tripping scares ghosts, and can make you hurt your leg. I dont suggest bringing a huge flashlight that everyone will see for miles, but a pen light or two to watch where you step. Perhaps one of those small mag lights.
First Aid Kit: You can get cut in a cemetery, even get broken up. Show some caution
Film: Extra and plenty of cmera film to photograph ghosts. If your using a digital camera, bring 2 or 3 memory cards incase one craps out. This happened to me several times. Take my advice
Headset Communicators: Never go ghost hunting alone. Bring a friend or two. Communicate using headset’s. If someone needs to locate another in an emergency situation, you need to be connected. especially if it is a big cemetary
Notebook and pen: Write down weather conditions, time, and incidents that transpired. Be clear and perform a full investigation. Record EMF readings and other variables that will help you next time by going during the optimum conditions
Recorder: Camcorder, Tape Recorder, Or digital recorder with a very sensitive microphone. You may catch voices and words that noone in your party said.
Watch: Its important to record the time you took the pictures. Like roll1 4:00-4:15
