Ocean Zone Divers held a NAUI Trimix Workshop in April 2001 at Lysekil, Sweden for NAUI Scandinavia. Two candidates take up the challenge:

- Peter HALBERG of SJOJUNFRUNSDYK
- Göran  MUNTZING of H2O at Lysekil

This was the first time such an event was run in Sweden and they are now the first two NAUI Trimix Instructors on Swedish grounds. The workshop was run in Lysekil, a fantastic region located on the banks of a fjord. This is one of the best dive sites of the country du to its unique marine life. The dive center H2O run by Göran, was our base for the course and the peer was just 50m down the road. The dive sites can be reached in less than 15 minutes.

Lysekil is also the HQ of SI-TECH one the main suppliers for dry suit valves. They hold 50% of the world market. The visit to their factory was a pleasure and actually very interesting.
