Hi there,
These units are all full spectrum ultrasonic recorders for leaving out on site.
The Elekon Batlogger M can also be used hand-held for active surveying, though they don't have a sonogram display.
The Titley Ranger & Chorus, Elekon Batloggers A, A+, C & S2, Pettersson D500X and Wildlife Acoustics SM4BAT FS and MINI BAT 2 are passive recorders. There is also the Elekon Batlogger WE X for long-term bat monitoring of wind turbines.
The Mini Bat 2, Ranger & Chorus can be used for both acoustic (birds/frogs) and ultrasonic recordings.
If you want a unit that can be used both actively and passively, the Batlogger M is an excellent piece of kit.
For passive use it's a matter of personal preference (and budget), as well as how you'll use them (see below).
Choose whichever one has the features that suit you best and if you need some help choosing, call me on 0333 9000 927 (+44 333 9000 927 from outside the UK) or email me.
You'll get a free bat calls book worth £35: either British Bat Calls by Jon Russ, Social Calls of the Bats of Britain and Ireland by Neil Middleton et al, Bats of Britain & Europe by Christian Dietz & Andreas Kiefer or Is That a Bat? by Neil Middleton; with the Titley Ranger, Elekon Batloggers A+, C, M & WE, Pettersson D500X & D1000X, Wildlife Acoustics SM4BAT FS.
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."
