Hey John,
That's a good one! No, I'm pretty sure my dog is not a registered member of this forum, so he won't be able to comment.
Actually, I wrote that in response to the reviewer at the link I provided having said that the PCM-M10 allows you to bring the ultrasonic frequenicies down so that we can hear whatever's happening up there.
I suppose a lot of people would say, "been there, done that," but I'm a noob at recording stuff, so it's appealing to me.
Mike
