If you're planning to take the plunge, Key Dives in Islamorada, Florida, offers PADI and SSI courses for beginners, certified divers, and aspiring professionals. Options range from Discover Scuba Diving and Open Water certification to advanced and specialty courses, Rescue Diver, and Divemaster training.
Whether you're trying scuba for the first time, or working toward a diving career, this guide explains the available courses, their requirements and published prices, and the multi-dive packages to consider when planning your trip.
1. Discover Scuba Diving in Islamorada, Florida: Try Diving Without Certification
If you're never tried scuba diving before, Key Dives' Discover Scuba Diving experience offers a structured introduction to the equipment and basic underwater skills before heading out to a local reef.
The one-day program begins with a safety briefing at 8:30 a.m., followed by pool practice. You'll learn basic hand signals, practice using a regulator, and work on skills such as clearing your mask before joining two guided ocean dives in Islamorada.
Participants must be at least 10 years old and complete a medical questionnaire. Basic swimming skills are helpful but aren't mandatory for this introductory experience. Remember, Discover Scuba Diving is an introduction, not a full certification. If you want to continue diving independently within recreational certification limits, consider Open Water training instead.
As of October 2026, the Discover Scuba Diving course costs $225, which covers equipment, a half-day pool session, and two guided dives. Want more time underwater? You can add another day of diving for $160 without repeating the pool training. If you don't know how to swim, let Key Dives know before booking. They also offer private sessions with more intensive instruction at a small fee.
