Batseeker 4 Ultrasonic Bat Detector

​Would you like to listen to bats on your evening walk or nature hike? Then the Batseeker 4 is the gadget for you! Perfect for budding scientists, nature enthusiasts, conservationists, and educators, the Batseeker 4 is unfortunately for the time being OUT OF STOCK. For a review of  the Batseeker 4, see Al Milano's Bat Detector Reviews.

​The Batseeker 4 lets you hear ultrasonic bat calls during evening flight and feeding activity. State-of-the-art digital frequency division technology makes the Batseeker 4 easy to use, requiring no tuning. It simultaneously covers the entire sound frequency range (20-100kHz) of most species of bats, as well as rodents and certain insects. The highly sensitive Batseeker 4 is based on a precision MEMS silicon microphone with a high signal-to-noise ratio. It samples bat calls every 1.1 milliseconds, with a sample frequency of 400kHz and a resolution of 3kHZ.  You can record bat sounds directly from the built-in speaker or from the audio jack using a 4 conductor 3.5mm male-to-male audio patch cable to connect it to a computer or smart phone with an OMTP audio jack or CTIA-to-OMTP adapter. The Batseeker 4 also works with stereo headphones or earbuds.
The compact portable design of the Batseeker 4 allows it to easily fit in your pocket. Two standard AAA batteries are required (not included; Batseeker recommends environmentally friendly Sanyo eneloop low-discharge NiMH batteries). A pair of 750mAh AAA batteries will last for several hours of continuous use on a single charge. The Batseeker 4 digitally filters out the low-frequency sounds picked up by the sensitive silicon microphone and divides the remaining ultrasonic component by 10, right into the audible range for humans. The Batseeker 4 uses advanced digital signal processing to restore the incoming signal strength in the audible signal output, so that nearby bats sound louder than distant bats. The advantage of frequency division over heterodyne conversion is that there is no static and no tuning is required: you will never miss a bat call by being tuned to the wrong frequency!
