Comments about Sima Sima MZM-1 Zoom Microphone:
Making race video's can be a challenging envirment, the mini digatal microphone has worked perfecly without exception.
I carry it around in a bag in which it gets banged around and ruffed up pretty good, it works every time, I have been using the mini microphone for a year and a half with no failures, you can not ask more than that.
Also I can stand next to a running race car with the zoom on and get just the audio I want on the video, also I just lay it on the counter in the press box and can pick up the track announcer for the call on a race.
I would doubly recommend this micropohone for any use plan on.
