The operator’s structured description highlights prerequisites: a PADI® Rescue Diver card, Emergency First Response (CPR and First Aid) within 24 months, a medical statement signed within the last 12 months, and logged-dive minimums (at least 40 dives to begin; 60 to earn certification).

Catalina Sidemount Training: personalize your setup

3 DaysUp to 4 per classAdvanced configuration & gas management
Sidemount configured cylinders on the shore
Sidemount training covers harness personalization, hose routing and gas control.

A focused three-day sidemount course teaches configuration, gas management and balance for divers seeking a different approach to equipment and trim. The operator notes small-class instruction (up to four students), mandatory paperwork including a medical and Diver Information form, and safety policies such as the instructor’s right to cancel dives for intoxication. The course expects students to be fluent in English for safety briefings and to bring certain basics — swimsuit, towel and sunscreen — while tanks and regulators are supplied.

Students should plan to bring or acquire a sidemount harness for the program; required e-learning materials and harnesses are typically not included. This course suits experienced open-water divers who want to refine buoyancy, streamline gas handling and adopt a system that can improve comfort in confined spaces or on multi-cylinder dives. For seasoned Santa Ana-based divers, it’s an efficient, professional class to expand technical competence in a supportive small-group environment.

Private open-water certification uses Catalina’s kelp gardens and shore-based dives.

The three-day private Open Water program offers concentrated, shore-based instruction on Catalina Island. The operator emphasizes small private classes (up to two students), inclusion of full gear for training days, and a shore-dive focus that takes advantage of Catalina’s diverse kelp forests and marine life.

Avelo — an innovative tank-based buoyancy experience

2 DaysIncludes 2 dives and gear rentalJetpack + Hydrotank system

The Avelo system makes buoyancy control a function of the tank itself.

The Avelo Experience markets a distinct approach to neutral buoyancy: the buoyancy control device is integrated into the tank. The system consists of a Jetpack and Hydrotank; by adding or purging water from the Hydrotank, divers modulate weight and achieve a stable neutral position. The operator describes the Avelo system as roughly half the weight of standard scuba, promising a lighter, stable feel and the potential for different underwater movement dynamics.

Listings indicate the Avelo program typically spans multiple days and includes dives and gear rental. For advanced recreational divers or those curious about alternative systems, this is an opportunity to test a novel configuration that changes how you negotiate trim and buoyancy. Travelers from Santa Ana who value equipment-led experiences and controlled instruction will find this an evocative way to reimagine familiar dive profiles.

Deep Diver specialty trains for planning and executing dives to extended depths.

This two-day private specialty prepares experienced divers for planned deep dives to depths of up to 130 feet, combining shore-based training and required deep dives. The operator lists prerequisites and safety policies similar to other courses: completion of required medical and training paperwork, the instructor’s right to cancel dives for intoxication, and the need for English-language comprehension for safety briefings. The class size is intentionally small to allow focused coaching on deep-dive planning, gas management and ascent profiles.

Included in the course are required deep dives, professional instruction and drinking water; required e-learning materials, ferry travel and accommodations are not included.
