much you argue against them, DAT recorders have one huge advantage
over both the tape and minidisc recorders, and that is where
you can record up to 11 hours of audio and then be able to
instantly transfer it into your computer in minutes. Initially
DAT recorders were not held in too high a regard since they
have a minimum recording range of 300Hz when EVPs are said
to be recorded at a much lower frequency. However, despite
this we have added an Olympus 2100PC DAT Recorder to our equipment
following a few experiments and trials regarding its potential.
These produced a positive result, and one particular recording
can be found on our evidence page.
Because of their size and light
weight, these recorders can be put pretty much anywhere and
left for the entire investigation - two AAA batteries can
record approximately 20 hours of audio and the internal memory
itself can record 11 and a half hours of continuous, uninterrupted
audio. Such potentials of its use could be, for example, to
monitor a trigger object to ensure no tampering. Or it could
be left in a location and then have that area sealed so that
no out-side noise can be recorded.
