Hello all,
Just as follow up to the two previous threads on bat monitoring using
recorded sounds from bat detectors. To those who weren't involved I asking
for help in choosing a recording tool to record output from electronic bat
detectors. This was purely as a scientific monitoring tool to map bat flight
paths. But I had issues with battery life, recording times and analysing
long lengths of blank recordings that only had the occasional bat record.
I finally realised, based a lot on what was said here, that I had to go with
Anabat, I bought one to try out (Detector and data logger) and then managed
to secure the monies to buy another 35 Anabat recorders, with the ZCAIM
Compact Flash recording unit, for the actual project.
The money is easily recovered from the time saved in analysing the results,
setting up the units in the field is so so easy compared to fiddling with
other types of detectors and minidisk or jukebox recorder options, the
standard battery life is good (lasting about 7 days in the field) and using
an external battery is easily done.
Simple analysis, counting the number of bat events, time of the event and
whether the bat was a horseshoe bat or a non-horseshoe bat is very quick and
easy to do with the Anabat Analook software.
Many thanks everyone for your help.
Graham
