Wildlife Acoustic – new SM4 – Song Meter


We have been using for our project the very reliable and robust Wildlife Acoustic SM2+ Song Meter (with external 6V lantern batteries to extend its deployment to 3 months). Wildlife Acoustic recently announced of a new and improved sensor – the SM4 Song Meter. It reportedly is lighter, more user friendly, and more energy efficient (which is great news). If you are starting your acoustic monitoring project now, these may be the sensors to keep in mind.
