Hi there,
What can I say about these acoustic recorders?
They're from Wildlife Acoustics and Titley, so you can rely on the quality and the results.
Of the Wildlife Acoustics models, the SM4 will produce the best results, but the Mini isn't far behind (though with only one channel as standard - optional second microphone is available). The Micro is a smaller and more affordable option for those who don't need deployments longer than 150 hours.
Titley's Chorus is a tough little recorder that comes with one acoustic microphone, but you can add an additional acoustic microphone or an ultrasonic microphone to record bats at night and birds/frogs during the day. Recording for up to 40 nights full spectrum ultrasonic or 300 hours of acoustic recording, and with built-in GPS so you can use it for transects.
I want you to be 100% happy with your purchase so call me on 0333 9000 927 for advice.
Warm Regards,
Martin.

Comment from a client:
"My bat detector microphone failed during a dawn survey and knew that I had a group of dusk surveys starting in two days time. I was not in a good place as I did not have a spare, but my equipment was less than a year old.
After my survey I contacted Martin by email and he called me back on the same day, a few hours later, after a quick nap. He told me he did not have a part in stock, but had already contacted the supplier on my behalf.
The next day I received a replacement part, free of charge and express delivered from Switzerland. I thought it was amazing, and could not believe it was resolved so quickly.
Due to Martin's exceptional service I was good to go with the surveys, and I really would like to thank Martin and Wildlife Countryside Services for making the dusk surveys happen."
