That’s precisely what you get with the Two Tank Dive offered by Aqua Action Dive Center in St. Thomas, part of the US Virgin Islands. For $200 per person, certified divers can explore some of the most impressive underwater sites in the Caribbean, all while enjoying the relaxed, friendly atmosphere that makes this experience stand out.
What makes this tour particularly appealing?

Exploring the Two Tank Dive Experience in Detail

Aqua Action Dive Center offers a well-rounded, professionally managed experience that emphasizes safety, fun, and authentic discoveries underneath the waves. Their small boat, only 32 feet long, limits the number of divers to 12, making it easier for the crew to keep a close eye on everyone and cater to individual needs. This setup fosters a more personal connection—not just with the guides but also among fellow divers, which many reviews highlight as a highlight.
The Itinerary: What Will You See?
The tour typically departs from the Secret Harbour Beach Resort, a location known for its calm waters and convenient access to excellent diving sites. You’ll start with a briefing from your knowledgeable Dive Master, who will explain what to expect and how to handle your gear. The first stop is usually a Caribbean reef teeming with colorful fish, sea turtles, and possibly lobsters or rays. The reefs in this region are known for their clarity and healthy marine life.
After your first dive, you’ll enjoy a surface interval with complimentary water and fresh fruit—simple pleasures that keep you energized for the second round. Then, you’ll hop back in for more exploration, often visiting a shipwreck or another reef, each offering different visual and marine encounters.
What Makes the Sites Special?
It’s not just about the scenery—many reviewers mention the impressive variety of marine life. One diver noted seeing “so many amazing fish, lobsters, rays,” and appreciated the patience and tips from the dive masters. Wrecks add a touch of history and intrigue, providing a different perspective compared to coral reefs.

All diving equipment—tanks, weights, wetsuits, masks, fins, regulators—is provided, streamlining your day and reducing equipment rental costs elsewhere. Plus, the small group size means your guides can tailor the experience and ensure safety.
Water and fresh fruit are included during surface intervals, which might seem like small touches but are appreciated by seasoned divers and beginners alike, helping stay hydrated and energized.

Considerations for Travelers
While this tour offers excellent value for certified divers, if you’re not certified or haven’t been diving recently, this experience might not be suitable. The requirement for recent experience ensures safety but also means this tour is best for those with some diving background. Plus, being weather-dependent, the trip could be canceled or rescheduled in poor conditions, so flexibility is wise.
Who Would Love This Tour?
This experience is ideal for certified divers looking for a small, personalized, Caribbean diving adventure. It’s perfect if you enjoy exploring wrecks and reefs in a relaxed setting with a friendly crew. It also suits those who appreciate good value—everything from equipment to snacks is included—and want to avoid large, impersonal tours.
If you’re traveling with friends who share your diving experience, or seeking a friendly crew to enhance your dive, this tour hits all the right notes. It’s less suited for absolute beginners or travelers on a tight schedule who might prefer more flexible, introductory options.
