Choptima Training

TDI – Advanced Wreck Course

The TDI Advanced Wreck course can be completed on your Dive Rite Chest Mount O2ptima CCR. This is a great opportunity to gain proficiency learning how to dive your CM O2ptima in an overhead environment and complete dives that require full penetration with navigational decisions. Most of our instructor team are dedicated metal heads and cave divers and we love being able to introduce divers to these environments on the O2ptima CM. The Choptima by its very nature is one of the best designed CCRs for wreck penetration and our instructors will be able to show you how adapt the unit and your diving to this unique environment.
