It depends on how "formal" you want to be with documenting it. You could use the bare minimum and just bring your phone and a tripod, if not a rock or brick or something to keep it stable. If you want to be more professional with it, a camera and tripod, along with hearing protection if yo...

Definitely an N-5, or at the very least a Sterling.
