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 Skills, National Age Group and (Junior) Elite divers can join GBDF events as soon as they leave the diving pathway they were part of formerly, and will be regarded as full competitors straight away.
