Even though he takes his whole vibe from the creatures, we’re pretty sure Batman never actually did his due diligence in learning about the species. If he did, however, we imagine that he’d start by using this handy tech: the Echo Meter Touch 2, an iPhone and iPad accessory that can identify the ultrasonic calls of bats.
Interestingly enough, there are over 900 species of bats in the world, with nearly 4 dozen living in North America, alone. And each of these fascinating, yet elusive creatures emits a distinct ultrasonic sound undetectable to the unaided human ear. With this little device, which plugs into the Lightning port of your phone or tablet, you can not only listen for bats, but you can identify each distinct species in real-time, gauge their location via your onboard GPS, record the sounds and turn them into something human ears can hear, and even share them with friends or colleagues. Oh, and if you don’t have an iPhone or iPad, they make a microUSB version, as well. Get all of this and more when you purchase the clever device for $179.
