The new Rook 2 EMF Meter with data logging detects small changes in electromagnetic energy and temperature with alerts, logs and so much more. This detector is specifically designed for ghost hunting with an emphasis on detecting energy changes and proximity so you can be alerted to a presence and track down the source easily. The Rook is fortified to reduce outside interference and false readings. The Rook is built from our experience as paranormal investigators with features we need for quality evidence, documentation and source tracking.

Data recording to a memory card
Flag marker and alerts for reading spikes
Highly sensitive EMF detects even small changes
Quality detection fortified from most interference detecting NATURAL magnetic and man-made EMF
Balanced to sit upright on its own for viewing in 360 degrees
Rechargeable battery, speaker switch, SD card port and more
 
Theories within the field of paranormal research suggest that these fluctuations may indicate a presence of a paranormal nature. Given that, an energy (EMF) sensor is a popular, easy-to-use tool to detect spikes in electromagnetic energy. Once all sources have been ruled out, changes on this meter may signify activity or communication from the beyond or the unknown. Spikes and fluctuations, on the Rook, are indicated by the dual lighted panel on the top with an audible buzzer to indicate proximity/strength.
 
Data Logs, Flags, Change alerts... all in one compact device.
Seeing a reading spike during an investigation is helpful. But what if you could see every sampling of all environmental readings on one timeline? Now you can with this new evolution - Rook 2. This new feature takes readings from the sensors and records them to an SD card which can be viewed later in a timeline graph or spreadsheet.
 
Spike Flags for special review.
While logging, Rook 2 will highlight significant spikes with automatic “Spike Flags”. During your investigation, Rook 2 will review your data live and determine if a change in the environment indicates something you should review and flag it for you. The log will be marked, a light will illuminate and an audio tone will alert you to this trigger. This gives you the opportunity to mark a certain point in the data yourself for special review.
The spreadsheet will be marked to indicate which sensor was triggered:
EMF Spikes: "E"
Temp Spikes: "T+" for temperature rise and "T-" for lower spikes
 
Review results on your computer.
The built-in data logger stores all investigation information on a memory card. You can open this data in any spreadsheet or graphing program of your choice to scroll through the readings, graph it for analysis and present to your client or team members. Just pull the SD card out, insert it into your computer via any SD card reader and load the CSV file into the app of your choice. We use a CSV (Comma Separated Values), a standard data format that just about ANY graphing program or spreadsheet application can display such as Excel, Google Sheets and Numbers. Once imported you can create graphs and analyze to find patterns and anomalies.
 
Multi-Use Display
The Rook 2 utilizes a super fast LED screen to show the exact readings from each sensor. It shows both EMF and temperature readings alongside other helpful information at a glance. Beyond that, it will highlight readings when a spike is detected. It will also indicate whether the last readings were higher or lower than the last. You can also monitor battery level and confirm that the SD card is present and recording.
 
EMF Meter with Sound
The Rook utilizes a highly sensitive Electromagnetic Field Sensor detecting even small changes in the electromagnetic field around the device. The display shows you an exact reading of the EMF strength in addition to a traditional lighted scale. You will also hear when spikes occur with an audible tone indicating EMF spikes. Theories within the ghost hunting field suggest that these spikes may signify activity or communication from spirits on the other side. Given that, the use of sensitive and reliable EMF detection during an investigation is important to document. The speaker can be turned on/off as you desire.
 
Ambient Thermometer
The Rook 2 contains an ambient temperature sensor with a real-time digital display. In addition to the digital readout there are LED light indicators that light to alert you to spikes or drops in temperature. Blue when the temperature drops and orange/red when it gets warmer. The unit of measurement can be switched to display Fahrenheit or Celsius.
 
How are the Rook readings different from other EMF meters?
When compared to other energy meters the Rook towers above in many respects. The Rook has been built, specifically, for paranormal investigations from years of experience knowing what we wanted in an easy-to-use, go-to sensor.
Sound and lights.
The Rook includes a sound alert which gets louder and faster as an audible indicator of EMF strength and proximity. You will hear a progressive change in tone as an indicator in addition to the light panel. The tone is made light enough to not interfere with potential EVPs but loud enough for indication as you scan the room.
 
Fortified from interference.
As you may know, many EMF meters are broadly affected by frequencies such as those produced by radios, walkie-talkies and cell phones. By ruling out these commonly-used frequencies, the Rook is NOT nearly as susceptible to these kinds of false readings, making it a stronghold of quality evidence. It is, however, sensitive to magnetic and electronic frequencies so you can easily track down sources of EMF leaks which can have adverse effects to those exposed. Note: while we have done our best to rule out as much interference as possible, as technology changes there may be some device models using frequencies not covered.
 
High sensitivity.
The Rook offers a high resolution, highly sensitive reading to alert you to much smaller changes in the environment with a sound alert to indicate proximity. The Rook allows you to see and hear even small fluctuations in energy change. The Rook's dual-light panel indicate energy change. These lights will pulse and get brighter to indicate fractional changes in strength.
 
Long-lasting rechargeable battery.
The battery on the Rook lasts a long time and will, likely, get you through a few investigations. It's rechargeable via standard USB-C.
