2X Battery Life (AA model)
Get up to 420 hours' deployment (double that of its predecessor) with just eight AA alkaline or NiMH rechargeable batteries. Choose whether to deploy with four or eight batteries.
Lithium-ion Battery Life (Li-ion model)
Deploy with one to six 18650 Lithium-ion batteries for up to 1,040 hours of recording time (separate lid accessory no longer needed)—an ideal solution for remote or otherwise difficult-to-access sites.
IP67 Weatherproof Housing
Deploy with confidence, thanks to enhanced, IP67-rated weatherproof housing that’s built to withstand even the most rugged terrestrial deployments and harsh elements.
Added Tripod Mount
Quickly deploy in a variety of habitats/landscapes/environments via the newly added tripod mount. Use off-the-shelf equipment for a more flexible setup.

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."
