GBDF Masters competitions are open to divers from 16 years of age onwards, from both the UK and abroad (divers under 18 years old need to be chaperoned).

While different GBDF competitions have different formats, all feature a novice event and a full masters events. Additionally, the events are split by age group.

Former National Age Group and (Junior) Elite divers will only be able to participate as guests for the first 2 years after their last NAG/(junior) Elite competition, and will become full competitors after that time.

Former Skills divers can participate as full competitors straight away.
