I have had this bat detector for a couple of weeks and use it nearly every night. Having used an analogue bat detector for many years this is just so much better and takes out the guess work. We have both Soprano and Common pipistrelle and the graphics really do show how different the calls are. It is very straightforward to use as it simply plugs into my iPad Air 2 and the app springs into life. The dedicated app again is straightforward to use. It is useful to able to transfer the recording files to my computer for record keeping. I like the location of the recording too – a very useful feature if you travel some distance in one evening or just mapping out where and when you saw which bat species. I am not sure I would need the Pro version – as an amateur the non-Pro version is more than adequate. It does drain the iPad battery a little quicker and so it's important to remember to charge if it is going to be used for many hours in one night (or alternatively take another iPad or iPhone and charge the drained one). I found grabbing screenshots a bit tricky on the fly but now go back to the recorder and grab a screenshot from there for my records. All in all an excellent piece of kit.
The Echo Meter Touch 2 is a great piece of kit that is easy to use. Simply download the free app and connect the Echo Meter Touch 2 to the Lightning port of your iPhone or iPad. The connector is short, so the Echo Meter fits snugly against the edge of your phone or tablet. That means that you have to remove any protective case around your iOS device first, and this makes using the device, especially when stumbling around in the dark, a bit precarious. Since the Echo Meter is also fairly thick (its edge sticks out above the edge of my iPad), you can't just make the hole in your case wider to fit it in, since that would mean removing the edge of the case along the top, which would compromise its solidity. If only the connector had been a bit longer, it would have been usable with regular cases.
The app can be downloaded for free and is quite intuitive to use. In Live Mode, the app will identify bats that are heard through the Echo Meter, but I could only get an identification while recording, never when simply listening without activating the Record button. It is not clear from the manual whether this is intentional or just a quirk from my listening sessions. Recording is done in a clever way – recordings of what turns out later to be noise are thrown away automatically – but you still end up with more than a few Mb on your hard disk: 120 Mb during my first session. Some short recordings of noise will also get a name, so don't count on the names of your files indicating the number of observations, you should really go through them and look at the sonogram.
All in all, a great invention (I am finally sure of my observations, which I never was with my old detector), but I would have liked to keep the case around my iOS device when using it.
