useful software for syncing many files with no timecode

I’m an Assistant Editor who works in documentaries. I wanted to let Premiere users know about an inexpensive third-party software, Syncalia 3, that has been incredibly useful to me. I frequently run into situations where there’s verite footage by multiple cameras that are supposed to sync with each other (and with separately-recorded sound) but there’s no timecode or timecode that doesn’t match, no clapper, no camera reports explaining what clips are supposed to sync with which other clips, etc. I thought that knowing that this software was an option would be helpful to Premiere users.
