Hey Guys doing the Tamaulipus 155' and Naeco 140'. How do you guys dive these wrecks regarding Bottom time ? The dive shop DDC said no deco and they ony bank 30% and air. Don't make sence to do a 2 hr ride for a 10 minutes dive. Whats the average depth on these 2 wrecks? Are there any other LDS for gas? Any help would be appreciated.
