is designed specifically to 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" and validate any temperature change around the device from up
to 50' away (line of sight).
can also help investigators become more efficient and thorough by helping to monitor
remote unattended areas throughout a house or building during an investigation
and help direct attention to an area that may have paranormal activity. In addition, the ATDD device utilizes RED LEDs
for a "+" temperature change and BLUE LEDs for a "-"
multi-purpose push button is used to "Tare" the circuit and mute the
