How to choose a bat detector

With our new SM4BAT Full Spectrum and Zero Crossing recorders shipping soon, you may be wondering how to choose the best bat detector and recorder from our product line up.

What they all have in common

All of the Wildlife Acoustics bat detectors have the ability to record bats. They are all equipped with the low noise FG microphone element, making for superior recordings in a variety of climates and conditions.

Passive vs. Active

Our SM3BAT and SM4BAT are weatherproof passive bat detectors, meaning that you may leave them unattended while they record, sometimes for weeks or months at a time.

Can the Echo Meter Touch be used for bicycle transects?

For our resourceful customer Peder Halverson, the answer is yes.

Wondering know how he did it? Peder shared the details with us:

"It’s simply a camera monopod fastened to the bike’s front wheel frame, a wooden platform fastened to that, a cardboard iPad mini case box glued to that, the iPad mini in the carboard secured by a Velcro band. The module’s microphone is covered by a windscreen salvaged from a Zoom H2 recorder that was once used to record bat calls from a Petterson unit. The monopod pole can telescope up farther, but I like it this way for better visibility of the road ahead. The iPad can rotate on the monopod either this way, giving better visibility ahead, or it can rotate so that the screen is always visible to the rider. It likes to ride this way, slowly rotating to this orientation.

This method is being compared with the method in which the iPad is slipped into the rope pocket on the back of a backpack. So far the two methods seem to give equally good spectrograms, even though one might imagine the pole method to give less audio reflections. The backpack method allows the iPad’s cover to remain open, so that the screen is visible to automobiles to the rear, acting as a great additional reflector. It also feels a lot more secure for the iPad and module.
