Extended Range Course (55M)
Some dive sites offer amazing things to see deeper than 40 meters, but are beyond the depth of your current certification. Using Helium is now very expensive and becoming harder to find so this Extended Range course is perfect to achieve depth up to 55 meters using air as your main breathing gas.
