Recorder - Can be digital or tape. They serve to capture so-called FVEs (Electronic Voice Phenomenes), also mandatory in an investigation. You'll be blown away by what you can record! Some recorders are sound activated, so he only turns on and records if he notices some sound in the near environment, so if he calls and no one has said anything, he probably captured a sound from the beyond. Digital recorders are easier if you want to analyze this sound in a computer program, it will suffice a cable to pass the recording from the recorder to the computer. In the tape recorder, it is more difficult to analyze in a computer program. But there are those who prefer the good old magnetic tapes. They are not usually very expensive, they cost on average between $ 50 and $ 200 but you can even use recorders or applications of your own Smartphone. Image Source: Daily Republic. Radesthetic rods - Another inexpensive option, as well as the compass, to lead to an investigation are the radestesthetic rods. But there are controversies ... Many believe that what moves the rods is nothing more than the unconscious movement of those who hold them. Others believe that the surrounding magnetic field is going to influence the movements of the rods. Anyway, if you want to make radiestés rods is just to do a quick search on the internet that you will read more about them and learn how to do, it's cool. Thermometer - one of the hallmarks of the presence of ghosts is to leave the environment cold as a refrigerator. This is because it is believed that when a ghost tries to materialize it steals energy from the environment and heat is a form of energy. They thus generate "Cold Points". Since it is always good to have solid, measurable records instead of just saying that you have felt this or that, being able to record the sudden drop in temperature of a particular point in the environment is very interesting. A digital temperature meter costs around $ 60.00. Walkie-Talkies - It's interesting if you have more people in your research group. Very useful for communicating when everyone is in an environment or home point, if someone hears or sees something, they can ask or report immediately to the colleague. But be careful, walkie-talkies can interfere with the results, as many devices end up capturing radio waves. Sometimes the walkie-talkies themselves are used as instruments by the ghosts that end up manifesting through them. They cost about R $ 70.00 per pair. Cell Phone - Obviously for emergencies or whatever, but cell phones can interfere with the other electronics used in the investigation, so be careful. It is good that you leave it off while reading, and only switch on when necessary. Powder (talc) and Black Plastic - This is very interesting and can be scary. You can try to capture the "footprints" of some spirit with this, just pick up a plastic (which can be an open garbage bag in the middle) black, put on the floor where there are history of apparitions, sprinkle talc or flour on it and wait. When you check in later, you may find that the energy of a ghost has stirred the dust, or even imprinted marks on it. Just make sure you tell other people in the investigation that they will not go there. Strobe Light - you must have gone to a ballad where you had one of those. They blink so much and so fast that our movements seem to be in slow motion or that we move at intervals like photos. This is the same fan principle, explained above. As the lights flash, isolate images that would otherwise move too fast for the human brain to solve, you can do the test again using a powered fan. Put a strobe light pointed at it and you can see the propellers. So during an investigation you can turn on a strobe light in the dark while watching, it goes that "someone" appears ... Such a light costs on average $ 200.00.
