Re: clock sync (was Digital Recorders: a Marantz 661?)

In some cases absolutely. That said, using a clapper imposes a fair amount of 
work and structure on the recordists. This can be challenging in natural 
conditions with a short (or no) crew, many takes, no shot logs and no 
opportunity for do-overs.
I recorded material on lemur research in Madagascar some years ago. Several 
people's voices were recorded in real time in the field as well as video, 
ambience and lemur calls. A nightmare and not very good. These days I'd give 
the people personal recorders and lavalieres and then pick the lemurs up with a 
parabolic or an array. I'd sync in post.
