The TDI Sidemount Diver Course is the ideal specialty for any diver wishing to use this increasingly popular equipment configuration; either as a stand-alone course OR in conjunction with one of TDI’s other open circuit technical specialties such as Decompression Procedures, Extended Range, Trimix, Advanced Trimix, and Advanced Wreck. If this course is combined, the requirements for BOTH courses must be met. The TDI Sidemount Diver course teaches students how to utilize side-mounted primary cylinders as an alternative to the traditional back-mounted method.
