1.4. Technical restrictions for diving (updated on 14/06/2015)

Insulin-dependent diabetics (types 1 and 2):

- supervised by a minimum E2 and an E1 in an artificial setting up to 40 m (i.e. PE40)
- autonomous up to 20 m (i.e. PA20)
- Maximum duration : within the "no decompression limits"
- No more than one diabetic per dive group
