In general, Prospect days can be great for checking out the school and seeing what the coach is like. You shouldn't have high expectations of being noticed unless you've been in communication with the coach prior to the prospect day.
We (the parents) never spoke to a coach prior to going to a prospect day. We let our son reach out on his own behalf. Sometimes he did, sometimes he didn't - but we felt it was up to him to initiate contact. I also told my son if he was a good enough player to be noticed, the coaches would notice him. I also told him that if he wanted it badly enough, he shouldn't have a problem speaking for himself. We took him to schools that were aligned with his GPA and life goals. Three D-1 programs followed up with him and we let him handle EVERY communication himself (we were there for guidance when he needed it).
