Extended Range Limited Trimix

Extended Range Limited Trimix

SSI Extended Range courses are designed to take your diving to the next level. Whether you are looking for the excitement of deep diving, going beyond recreational diving limits, significantly extending your bottom time or enjoying the thrill of exploring deep reefs, wrecks and caves, Extended Range provides the training and experience necessary to complete your new adventure with confidence and skill.

Academically you will advance your knowledge and understanding of principles, procedures and theories specific to diving safely with a decompression ceiling.
