You want to sample bat activity at a single site at a building, in the forest or in the open field for a period of some weeks to months (daily operation status per SMS included).
Using the GSM-batcorder you can continously record bat activity at the height of a wind turbine nacelle or at the area of the lower blade tip with the mast microphone.
You will find the most current firmware for the batcorder 3.0 and batcorder 3.1 for download. In addition we publish the change history for the former firmwares. The most current firmware always includes all earlier changes, thus installation of the latest firmware installs all former updates automatically. Please see update instructions in the batcorder manual or in this pdf document.
