Scouting Using Scantrons

[Sue-San]

Hey everyone,

Last year, I saw a team (I think 1503 - correct me if I’m wrong) using some sort of scantron scouting system to scout. I would LOVE to get something like this set up for my team to use next year or even at championships, if possible.

If anyone knows anything about scouting using scantron sheets, I have a few questions:

-What devices do you need in order to make this work?
-Do you need a power supply at competition to run this?
-If your team uses this, how effective has it been?

Thank you in advanced!
