Conservation. Training. Community.

Extended Horizons is striving to make conservation and education available even when you’re not here on Maui! Taught by Extended Horizons Instructors, our On Demand ONLINE courses are a way to learn about diving and marine ecology from home! You’ll have access to the course material with your own log-in, and you can start/stop whenever is convenient for your schedule. Our courses allow you to go at your own pace through the lessons.

ONLINE Coral Reef Conservation Specialty

This Specialty is available to anyone!

Divers, snorkelers, ocean enthusiasts, all age groups…

Learn about coral reefs and their related ecosystems, challenges the reefs face, and ways each of us can help. Extended Horizons staff Instructors have created a series of educational video lessons, as well as online content that will enrich your understanding of the reefs. You do not need to be a certified diver to sign up, but each student will receive a Specialty Certification upon completion! A portion of the cost of your class goes toward Project AWARE non-profit to help protect our oceans worldwide. And especially now, with restrictions on travel, remote learning is a great way to keep that passion for the ocean going!
This series of lessons is formatted to engage the student, with  video and written content. The most in-depth learning comes from the custom video lessons, presented in easy-to-digest segments conducted by our Instructors. You’ll be able to review or revisit sections within your course, and take knowledge-review quizzes to reinforce your learning.

We are also offering an optional zoom meeting with an Instructor to ask any follow-up questions or continue discussions.

ONLINE Enriched Air Diver (Nitrox)

The PADI Enriched Air Diver course is PADI’s most popular specialty course. Why? Because diving with enriched air nitrox gives you more no-decompression time, especially on repetitive dives. If your air consumption is low, and staying down longer and getting back in the water sooner sounds appealing, then do NOT hesitate to become an enriched air diver; start the eLearning for this course today and move at your own pace through the lessons.

Upon completion of the eLearning, we will schedule a Zoom session with an Extended Horizons Instructor to go through the final portion of your course and issue your new Specialty Card!

This course is available to anyone who holds an Open Water Certification.

ONLINE Peak Performance Buoyancy

Excellent buoyancy control is what defines skilled scuba divers. Learn to glide effortlessly through the water, use less air, and ascend, descend, or hover almost naturally. Peak buoyancy also makes it easier to observe aquatic life without disturbing their surroundings. Do you want to master your buoyancy? Take this online course to learn about the concepts involved from our Instructors, at your own pace.
