Bat detectors provide a relatively inexpensive means of listening to and recording bat vocalizations. These ultrasonic signals are way above the range of human hearing and general use audio recording equipment. The bat detector electronically converts the ultra high-frequency sounds down into the range where humans can hear and audio recorders can capture. There are many, many models on the market. Our hands-on field experience with a Laar model BB-XL detector, coupled to an R-DAT machine, has produced stunning results.

A special thank you to Karsten Passior. He has gone to enormous lengths to compile the most complete bat detector comparison listing to date, available for download. Through his kind generosity we are able provide this in-depth comparison. This chart is a subset of a much larger list of detectors. It contains detectors that are currently available as well as those recently discontinued. Practical factors like the availability of a frequency display light (LED or LCD), one or two hand operation, weight, basic noise, sensitivity, filtering technique, power requirements, etc. are used to compare models.

Anabat is another popular bat detector designed to help users identify and survey bats by detecting and analyzing their echolocation calls.
