"The authors (a “famous ghost hunter” and an “international demonologist” who survived childhoods in homes tormented with ghosts, poltergeists and other paranormal phenomena before branching out into investigating cryptids, UFOs, crop circles and hauntings) do not come across as swivel-eyed loons. Their advice to would-be investigators is practical, especially about mental and physical preparation for investigations (eg. don’t use drugs, pay attention to feelings of discomfort, don’t go alone, don’t lie or ramp up the drama, etc) and the pitfalls of being in the media spotlight. There much here also about good equipment, good methods – even, should you choose to start a group, on choosing and registering a name. There is a sample investigation questionnaire and even a chart of types of ‘orbs’ caused by flash reflection off dust and bugs." - Fortean Times March 2015
