David, I'm just wondering how directional your Brinibox is (if at all).=0D

first advice is to take it out with a fitted windjammer or just=0D
wrapped around with something soft like a sock and see what you get.=0D
You will be disappointed with the stereo image, and the built in mics=0D
till pick up everything from every angle. Compare the stereo sound=0D
with the single image from each channel and I would be surprised if=0D
you hear any difference.=0D

The PCM-M10 has a high impedance input so you will get less hiss from=0D
a higher output mic. But what mic? For general outdoor use I would not=0D
advise a cardioid as they have a very wide pickup "solid angle" (Left=0D

Whatever mic you start out with you will soon want better if you get=0D
hooked. You don't mention stereo, and that basically doubles your mic=0D
costs, but it does give you extra information on wildlife behaviour.=0D

Look out for a secondhand quality gunmic of any sort and you will be=0D

And you will have to lug a reflector around everywhere. This is a=0D

Beware of systems which promise a lot for little money. I'd avoid=0D
cardioids in favour of any gunmic, and hypercardioids have bad rear=0D

ground reflections. Good in treated studios, bad in the big outdoors.=0D
