In Croatia the law divides between organized and individual diving. The difference is in handling and licence fees.
Organized Diving is diving under steadily supervision of a dive guide from a licenced croatian diving center or diving club. The dive guide has to record all supervised divers and their dives and has to supply oxygen, first aid, gsm, emergency plan etc. Like this you don’t have to pay for an individual divers card for 340 Euro.
This is every dive without supervision of a dive guide from a licenced croatian diving center or diving club. The individual diver needs to purchase a divers card for 340 Euro at the harbour authority.
