Grab parents to assist to bring you up to six. Repeat for any siblings, mentors, or other random persons you bring with you.

Or partner with another team who does have such a system for an event or two. You get the data and learn one way to scout.

If both of those ideas fail...
I would suggest running a 2-person team, with a backup 2-person team at any given time. Each person scouts one side of the field; the backups double-check.
