It’s a respected tec diving instructor certification that few achieve. If you’ve got the experience and are up for the challenge, then it could be your next step. When you earn this rating, you can conduct the full range of deep, open-circuit tec diving courses, including Tec Trimix 65 and Tec Trimix Diver.

At XTC we are committed to making safe and competent Tec divers that are able to meet the course performance requirements in a comfortable and repeatable manner. Tec diving has additional inherent risks (when compared to recreational diving) and we want to minimize these additional risks as much as possible. This means is that our training is performance-based, not time-based, so course prices are based on daily rates and your Instructor will discuss with you if additional training days are required.
