Tech Sidemount

    TDI's Technical Sidemount course, welcome to tech...

    This TDI course will have you wondering why you have always worn tanks on your back! With the easy access to the valves on the two primary tanks as well as the streamlined position, this is an amazing configuration.

    The course will ease you into the Tech mentality and introduce you to the precision required in all aspects of diving required prior to moving on towards Decompression or Overhead environment diving.

    Taught exclusively on the X-DEEP Stealth 2.0 harness by experienced instructors with small groups (Max 2:1 Student Ins ratio) we pride ourselves on training "leaders, not passengers".
