Other costs involved in this course

This course requires both knowledge development and in-water training for certification.

  • When you purchase a PADI eLearning course from Start Diving Online or directly from PADI, the cost covers the knowledge development portion only.
  • There will be an additional cost to complete the practical part of your course with a PADI Instructor. The cost depends on class size, location, and whether or not you need to rent equipment.

Most dive shops require students to provide their own mask, fins, and snorkel. If you already own a mask, snorkel, and/or fins, bring them to your instructor before your first in-water session. Some snorkeling masks and fins are inadequate for scuba diving.

Basic scuba gear, including a regulator, buoyancy control device (BCD), dive computer, and cylinder, may or may not be included with the in-water training cost.

You may also need to buy or rent exposure protection (wetsuit or drysuit) depending on the diving environment.
