Rebreather use is becoming increasingly popular due to the substantial advantages this type of diving offers the user. Rebreathers give the diver the luxury of silent bubbleless operation, warm moist breathing gas, and much longer no-decompression limits as well as shorter decompression penalties.

The Orca Dive Club Hamata stocks 2 Dräger Dolphin SCR (Semi-Closed Rebreather) with 4 cylinders (steel 4/5ltr.) and 2 bailout cylinders (2ltr.) so that visiting divers can rent the rebreather and save themselves the hassle of carrying lots of gear on holiday with them. The Orca Dive Club Hamata also offers user training for all those divers who have wanted to experience the absolute peace and quiet this type of diving offers.
