Since 2006 Chelonia’s ‘PODs’ have revolutionised the monitoring of wild dolphins and the smaller whales. These fully automated passive acoustic monitoring instruments detect porpoises, dolphins and other toothed whales (except sperm whales) by recognising the trains of echo-location sounds they produce.

The BatBug is different from other bat loggers: it uses the ultra-fast sampling (4MHz) and real time parallel processing developed in the F-POD to accurately select bat calls and store high-resolution details of each call so 32GB will store a year of data from solar powered BatBugs in remote wild places.
