TDI Sidemount Course

The TDI Sidemount Diver course is designed to introduce divers to an alternative equipment configuration where tanks are mounted at the sides of the body instead of on the back. Originally developed for cave and technical diving, sidemount has become increasingly popular among recreational divers for its increased comfort, stability, and streamlined profile underwater.

The course will be conducted in the beautiful cenotes of the Riviera Maya, including sites like Garden of Eden and others just 20 minutes south of Playa del Carmen, offering an immersive experience in calm, clear water ideal for skill development.

Course Topics Include:

  • Introduction to sidemount diving philosophy and benefits

  • Equipment configuration and gear setup for sidemount

  • Gas management using independent cylinders

  • Buoyancy control, trim, and efficient propulsion techniques

  • Valve handling, regulator switching, and emergency procedures

  • Streamlining for confined and overhead environments

  • Planning and executing sidemount dives

Course Structure:

  • Academic Sessions: Covering sidemount diving theory, equipment adjustment, gas management, and dive planning

  • Confined Water Training: Focused on buoyancy control, trim, equipment handling, and basic propulsion techniques

  • Open Water Dives: Typically 3 dives in cenotes, emphasizing skill refinement, problem-solving, and a fun cavern dive to apply what you’ve learned

Prerequisites:

  • Minimum age: 15 years old

  • Minimum certification: Open Water Diver

  • Minimum of 25 logged dives

Certification Outcome:

This course does not involve staged decompression or the use of high-oxygen mixes, but it is an excellent preparation for future training such as TDI Advanced Nitrox & Decompression Procedures, and Cavern.
