That is the whole thing. Marco is there to help you find a disc faster and get back to your round.
Put Marco on the discs you really do not want to lose.
Connect it before the round so it is ready when you need it.
If a shot disappears into the woods or rough, open the app and ring the disc.
Open Marco, tap the disc, and ring it. That is it.
Tap it, ring it, go find it.
