Spotlight on optional hardware attachments: The SMX-UT ultrasonic microphone

Looking to upgrade your bat recording rig? The SMX-UT is our most powerful and precise tool for omnidirectional bat recording.

As the higher end alternative to our SMX-US ultrasonic microphone, the SMX-UT provides a flatter frequency response and higher sensitivity at frequencies above 60kHz. It records up to 192kHz and it’s weatherproof, just like the standard SMX-US microphone. The SMX-UT has very little reduction in sensitivity off-axis, which means it can record bats in all directions. This is helpful for capturing a larger sampling of bat passes and echolocations.

And if your recording needs require a directional microphone, the SMX-UT is compatible with our SMX Horn accessory. This horn will transform the UT microphone into a highly directional microphone.

A New Way to Tackle White Nose Syndrome: Artificial Bat Cave

The deadly fungus that causes White Nose Syndrome has claimed more than 6 million bats since it was identified in 2006. It has been a crisis for bats all over the Eastern US and Canada. Yet despite desperate efforts by various research groups and organizations, the epidemic has sprinted on at an alarming rate, threatening eventual extinction for several bat species.

Last year, The Nature Conservancy of Tennessee employed an all-new strategy. They built an artificial bat cave. The operation is more complicated than it sounds. The cave needed to have just the right conditions – the wrong temperature and humidity could spell disaster for the already weak populations. It also needed to be free of humans, who have been known to accidentally spread the disease from cave to cave.

How to get the most out of your SM2+ recorder

How to get the most out of your SM2+ recorder

Hello again All,

So, pop quiz, what firmware revision are your SM2s running? Right now? Do you know where your firmware is?

All joking aside, keeping your firmware updated is one of the easiest ways to make sure that your SM2 recorders are running up to snuff. Every time our engineering staff releases a new version, you can be assured that bugs will be fixed and (maybe) a few new features will be added. Let’s take a look one of the great things that the latest firmware revision as of this writing (3.2.5) holds for you: the SD Card Speed Test.
