Well, the RF detector determines if there are radio frequencies that might be coming from cell phones, security systems, 2-way radios, etc. If we set an RF detector next to our K2's, then we can determine if the K2 is spiking due to radio waves. Basically, both the RF and K2 will go off together. In the event that the K2 lights up and the RF detector does not, there's a good chance that we are experiencing something paranormal in nature.

The KII meter, or K2, is essentially a type of EMF detector. This will detect electro-magnetic fields within about a 3 to 5 foot radius. The theory is that spirits/ghosts emit a certain level of EMF. The K2 has a series of lights and if the meter detects an EMF it will light up. The stronger the EMF, the more the meter lights up. The sensitivity of the meter has been specifically set for paranormal investigations.

In theory, the spirit can communicate through the use of the K2 if it is an intelligent haunt. We can ask the spirit questions and request that they light up the lights based on their answers.

The K2 will also work for residual haunts, but for obvious reasons, they cannot communicate.

Any time we use a K2, we will also use an RF detector.

I have been debating this question all day, and here are some thoughts on the subject. If you conduct a hunt during the day, the outside noise could drown out any evp's you might pick up. A lot of cars and people talking could interfere with the recordings. In a sense night time is more quiet so it leaves less margin of error when trying to capture an evp. Also I am guessing that sunlight can cause some glares on the camera lenses since light reflects off of windows, glass, and so on. I'm pretty sure that ghosts roam during the day, but night time makes it a lot easier to find them. Since we are not created as nocturnal creatures, our senses seem to be heightened in the dark, allowing us to hear more clearly.
DPRI plans on conducting daytime investigations and comparing the data/evidence to night time investigations to determine the necessity of night time investigating. We will keep you posted on our results as they come available.

An orb can be caused by a number of things. The most common causes of orbs are light refracting off of dust particles or reflections due to lighting conditions. Orbs can also be caused by energy being gathered by an entity. It is our belief that if the orb is not seen by the naked eye, it cannot be considered valid evidence of paranormal activity.

An entity is a disembodied "consciousness" commonly referred to as a ghost, spirit or (if of an apparently malicious or resentful nature) demon.
