/ Bat detectors?
could anyone recommend me a good bat detector?
I need one for my son's school project, and I would rather spend some money on a proper detector with recording and sonogram options than waste anything on a cheapo heterodyne type toy detector.
My favourite would be a used professional model, but unfortunately there appears to be nothing of interest on the standard auction sites or caving / bat enthusiast fora.
Has he had a good look in his utility belt? It might save you having to buy a new one.
What about an EM Touch, they plug in to an iPhone / iPad and you can use the Kaleidoscope programme to analyse calls.
Could be a bit pricey though.
I can recommend the Magenta bat 4, but there is no recording function. If you want something for recording you are looking at spending £200-£2000 depending on how serious you are.
I bought the British Acoustic Technology ‘Belfry’ Model. It’s pricey at £500 but can differentiate all British bats and even tell you whether they are young, male or female or indeed healthy.
Thanks for the advice, everyone!
I am a biologist and would keep any detector for myself once my son has finished his project, so price is not the most important issue, it needs to be a detector not a toy.
At my old institute I used a handheld Anabat detector when running along with the guys from zoology, but it will be in use during the time so I cannot borrow it, and buying that one would definitely be above budget.
I already had considered an EM touch 2, possibly the pro version if I can get a used one somewehere.
I don't know if there are any out there but I wonder if it is possible to get one with DSP technology. Radio has been revolutionised by using a spectrum Waterfall display of frequency v time. If you could get one that collected the ultrasound spectrum with the ability to download and display like that it would be rather interesting - would it work by if you did it by down conversion of the spectrum and feeding it into DSP software on a sound card?
There are apps you can use to process digital recordings of bat sounds, unfortunately the price of a decent ultrasonic microphone is roughly the same as the full detector setup.
The top alternative to the EM touch that I am considering actually is a USB ultrasonic microphone like the Dodotronic Ultramic coupled to an app for frequency conversion (for live identification) and recording (for documentation) running on a tablet.
I can vouch for the Magenta ones - good value and seem to be reliable and effective
Thanks, but apparently they are all heterodyne detectors without sonogram recording option , so not quite what I am after.
Based on your "likes" I seem to be the only person not getting the joke. Probably my age showing, but would you mind explaining?
Ah just a poor reference to Batman and his utility belt. In the 1960's TV series he seemed to have the most random things in it, 'bat-spray' 'the bat swatter' ,bat-kerchief', to name a few.
I've got a friend who develops DSP applications and hardware - usually radio related - I might see if he's ever thought of widening his scope ...
The best reply is the EM Touch, which now has Android support. It's a very cheap way of getting that facility. I'm going to get one - I only have a het detector I build a few decades ago.
Earlier this year Tom Randall and Pete Whittaker (AKA the Wideboyz) travelled back to their favourite crack haunt of Canyonlands National Park in Utah, where they established another hard first ascent in the White Rim – Black Mamba 5.14b –...
