Move your clinder from your back to your side, take the pressure of of your back and find more flexibility to move and enjoy your dive.

Why Side Mount?

  • Enables a unique method of buoyancy control which results in a more streamlined profile, reduces drag and moving much easier and more efficient.
  • Offers a greater comfort level. Sidemount equipment and harness are custom fit to each individual.
  • Carry the tanks separate from your harness to the water. Cylinders and weights are then mounted and attached in the water, making the entries and exits to dive sites much easier. (Eliminates many back issues)
  • The safest option in terms of air management.
