Ready for the outer edge of technical diving?

The Tec Trimix Diver course takes experienced tec divers and turns them into extreme divers who go deeper and visit pristine sites where few others will ever go. During the course, you’ll make dives as deep as 90 metres/300 feet, but once you earn this tough certification, there are few limits. Your training teaches you to build experience gradually and you do it because you’ve made it this far and have more exploring to do.
