One of the best instructional camps that uses a 3-man system is Donny Vaden's Camp at VA Tech. I have been the past 2 years and wish I had gone sooner. I waited 3 years before I went to a camp. At Donny's camp, there are a mix of NBA, D1, D2, D3, and veteran high school officials as evaluators. The on-court and off-court instruction is great and you usually work about 3 games a day.
I think the cost is about $225.00 (includes meals and dorms). There are usually about 60 officials there from VA/NC/WV area. Even one guy came from Texas last year. The dates this year are June 19-22. If anyone wants anymore info, feel free to e-mail me.
