The Peersonic has my 60 day 100% Satisfaction Guarantee & extra year's warranty

Hi there,

The Peersonic is a very affordable hand-held bat detector/recorder that can also be used as a passive detector/recorder.

Changing the microphone involves unscrewing the case and replacing the microphone circuit board (simple plug to fit). Each microphone comes with a different coloured control knob, so you know which microphone you have fitted.

To use the remote microphone, you need to fit the remote mic adaptor.

If you want an RPA3, with a 60 day 100% Satisfaction Guarantee and a FREE extra year's warranty, you'd better get your arse in gear and order yours today - there's usually a 3-5 day lead time on these, sometimes more.

What can I say about the Peersonic RPA3?

If you're looking for an active/passive recorder that's easy to use, affordable and records in full spectrum, this is certainly one to consider.

I want you to be 100% happy with your purchase so call me on 0333 9000 927 for advice, or drop me an email.

Warm Regards,

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."
