The ATDD is a new Paranormal device designed to specifically monitor and detect a +5 deg. / -5 deg. ambient temperature (deviation) change that occurs within an environment. When a temperature shift does occur, the device will react quickly and produce a unique, one octave "step" tone for each individual degree change. Incremental "+" changes have a higher pitch while descending "-" temperature drops have a lower pitch. This allows a paranormal investigator to "hear" any temperature change around the device from up to 75' away (line of sight). The intent of this device is to help investigators become more efficient and thorough by monitoring remote unattended area throughout a house or building during an investigation and then help direct attention to an area that may have paranormal activity. In addition, the ATDD device utilizes RED LED's for a "+" temperature change and BLUE LED's for a "-" change.

A single multi-purpose push button is used to "Tare" the circuit and mute the sound in any of the three configurations.

Saint Michael the Archangel,
defend us in battle.
Be our protection
against the wickedness
and snares of the devil.
May God rebuke him,
we humbly pray;
and do Thou, O Prince
of the Heavenly Host
by the Power of God-
cast into hell,
satan and all the evil spirits,
who prowl about the world
seeking the ruins of souls
