Wildlife Acoustics, Inc. is the leading provider of bioacoustic equipment and we have been using their (now discontinued) SM2+ sensors for our project in Cameroon. They have quarterly rounds of grants (up to 5,000 USD) for their equipment. The deadline for the next round is Nov. 15, 2016. Do you have a cool project in mind that would require acoustic sensors? Maybe you should think fast and put a proposal together. We will! We have been itching to try the new SM4 sensors in the field.
