More than one Reader suggested, that they'd like to see some of my detector reviews more conveniently located on the Blog. In other words, easier to navigate back & forth from - For ease of comparison, etc. One Visitor, informed me that they had trouble locating reviews of specific bat detectors they were interested in.
So, what follows, are a bunch of Mini-Reviews of bat detectors; with convenient Links to the full Reviews (including a couple of digital recorders at the end). I hope having all of these reviews in one Post proves useful for those trying to decide on a bat detector to purchase.
More than one of the Reviews are of machines that have been discontinued/replaced by newer models. But, I did not omit them, for the sake of completeness.
Beginning with some of the offerings from Wildlife Acoustics:
The single best-sounding heterodyne detector I’ve ever heard. A very capable and sensitive time expansion unit as well. Partnered with a Zoom H2 or H2n = A perfect combination; with well-documented set-up tips easily found on The Web. Confused about set-up? Use my settings! (approved by Mr. Pettersson himself):
I love the very compact size, and comfortable feel it has when held. I really like the green LED display, and the ability to fit this little detector in just about any pocket. I was happy to see a line-out jack: But later learned that it’s for headphones, only. Attempting to record bat calls with this unit will leave you disappointed. As per Elekon: The Batscanner was not designed for recording bat calls.
One can immediately tell how sensitive it is, simply by powering it on, and rubbing your fingers together in front of it. The microphone on this unit, is the now popular MEMs type. When in the field (without any man-made interference nearby): Pressing the power button will cause the unit to display three dashes " - - - " on the LED display. In contrast to powering it on indoors, where it will latch on to whichever electronic signal that reaches it first.
The unit simply displays the last frequency that was detected; until a new bat flies by, within it's range. You can just look at the display and see what the detected peak frequency was.
There is something I don’t like: battery changing. You need a small Phillips head screwdriver, to remove 2 small screws that hold the battery door in place.
Elekon Batlogger M: I simply cannot say enough good things about this detector. It is simply outstanding, with unprecedented abilities: It can detect – And record bats at greater distances than any other detector I’ve tested. How far? A colleague of mine in Germany, recently tested a Batlogger M to find it able to detect bat signals at distances of over 59 Meters!
