Sidemount Diving was thought to be a Cave Divers only domain, but due to the advances in equipment technology and greater availability of training, sidemount has exploded onto the mainstream market with divers of varying experience taking advantage of the many benefits Sidemount Diving has to offer.


The advantages of sidemount diving came early with technical divers realizing that the tanks, configured down the side of the body, create a lower profile in the water than the traditional backmount configuration, thus allowing access to, and exploration into spaces without disturbing the environment. Less Silt meant greater access to the under water world.

Cave divers could push further into unexplored cave systems by squeezing thru tighter restrictions. Wreck divers could push their way thru small hatches by unclipping the bottom ender from the hip D-ring and reef divers could use sidemount to navigate thru tight coral canyons hoping to reduce unintentional coral contact.


Another massive advantage for sidemount divers is the fact they have easier access to the tank valves in case of an emergency. If a tank valve blows, they can simply look down, identify the problem, and fix it while switching to the reserve cylinder in front of them. While in backmount, the hardest part of any emergency valve shutdown is to recognize were the problem actually is. In Sidemount, not only can you identify the problem quicker, you’ll also help in not wasting any of your gas while trying to isolate the problem.


One final benefit is comfort, considering the average technical rig weighs close to 60 kilos, the ability to don the cylinders while in the water takes away the burden of the weight on your body. You’ll enter the water with your simple sidemount harness in place and clip on the cylinders allowing the weight burden to reduce through buoyancy. This particularly appeals to those with back or joint issues or even the older generation as it frees up the spine so heightens the sensation of freedom as your diving.


Who this TDI course is for:

  • The SDI or TDI diver looking to expand their in-water skills and techniques
  • The certified diver who has interest in moving forward with technical diving education and expanding their equipment configuration options


Course prerequisites

(these requirements must be met prior to commencement of training):

  • Minimum age 18
  • Minimum certification of SDI Open Water Scuba Diver, or equivalent


What you can expect to learn:

The TDI Sidemount Diver Course takes an in-depth look at all of the following and more!

  • Gas matching procedures to include dissimilar volumes
  • Gas management utilizing independent cylinders
  • Psychological considerations of technical diving
  • Equipment considerations including:
    • Cylinder options
    • Regulator options
    • Buoyancy compensator/harness options
    • Proper weighting
    • Equipment configurations
  • Communication (light and hand signals)
  • Problem solving in a sidemount configuration
  • Diving in tight or confined spaces
  • Conservation
  • Water entries/exits
  • S-drills specific to sidemount diving


Some of the required skills you will have to demonstrate include:

  • Demonstrate various propulsion techniques such as the frog kick, modified frog kick, modified flutter kick, backwards kick, helicopter turns, and hand pulling if appropriate for the environment.
  • Demonstrate adequate buoyancy control; ability to hover at a fixed position in water column without moving hands or feet
  • Demonstrate adequate trim; ability to maintain proper position during the descent, bottom, and ascent portion of the dive
  • Demonstrate the ability to perform the following exercises while maintaining trim and buoyancy in the water column:
    • Unclipping and attaching sidemount cylinders
    • Perform gas switches with and without a mask
  • Demonstrate the ability to safely manage gas in independent cylinders
  • Demonstrate conservation, awareness, and back referencing techniques
  • Deploy a lift bag
  • Carry additional cylinders is optional in this course


What’s in it for you?

Upon successful completion of this course, graduates may engage in sidemount diving activities without direct supervision so long as the following limits are adhered to:

  • The diving activities approximate those of training
  • The areas of activities approximate those of training
  • Planned dives do not exceed diver’s current certification level


TDI Sidemount Diver minimum certification requirements:

  • Perform all land drills and dive requirements safely and efficiently
  • Demonstrate mature, sound judgment concerning dive planning and execution
  • Maintain an appropriate level of awareness and respect for the environment
  • Log all training dives


Course includes gear configuration session and three shore dives.  Course cost excludes equipment rental, our rental prices can be found at


Normal full course cost is $549, however if you buy the elearning during July 2020 you save $109!
