Discover the Big Island’s underwater wonders on a 2-tank daytime boat trip with Jack’s Diving Locker. Enjoy guided dives, top gear, and stunning marine life.
If you’re considering a day of exploring Kona’s vibrant marine environment, the 2-Tank Daytime Scuba Dive Boat Trip offered by Jacks Diving Locker is worth your attention. This experience promises a couple of guided dives, a friendly crew, and the chance to see some of Hawaii’s most iconic underwater sights—all in a comfortably organized package. Whether you’re a seasoned diver or just certified and eager to experience the reefs firsthand, this trip aims to deliver.
What we love about this tour is how it balances professionalism with a relaxed atmosphere. The certified guides make safety a priority, and the top-quality gear and hot showers onboard add a touch of comfort after a morning of aquatic adventure. Plus, the opportunity to observe sea turtles, dolphins, octopus, and even humpback whales in season is a highlight. On the flip side, a possible consideration is that you’ll need to be comfortable with physical activity, as moderate fitness is recommended. This tour is perfect for travelers seeking authentic reef encounters with a small group vibe—generally around 24 people.


The journey begins at Jack’s Diving Locker’s Kailua-Kona location, where you’ll meet around 8:30 am. This well-established company is the oldest dive shop in Kona, and their experience shines through in every aspect of the trip. The boat departs with a maximum of 24 travelers, which keeps things intimate and allows for personalized attention from guides.
Once aboard, you’ll be treated to light lunch, juice, water, and access to onboard hot showers and bathrooms—a thoughtful touch after getting wet. The boat itself is equipped for comfort, and your gear—tanks, weights, masks, snorkels, fins, wetsuits—are provided, although you can rent additional gear if needed. The crew is known for their knowledgeable guidance, making even less experienced divers feel at ease.

The core of this tour is two guided dives at Kona’s best spots. The first dive typically takes you to a site featuring stunning coral formations, abundant reef fish, and perhaps some eel residents. The guides, often experienced divemasters or instructors, will ensure everyone stays safe while pointing out key sights. The second dive is usually equally spectacular, with possibilities to see sea turtles, octopus, and even dolphins—which many reviews highlight as a favorite part.
In winter months, there’s a good chance to spot humpback whales surfacing between dives, adding an extra layer of magic to your day. The guides are skilled at spotting and identifying marine mammals, so don’t be surprised if they stop the boat to let you watch these gentle giants.
One of the most praised aspects of this tour is the diversity of marine life. Reviewers frequently mention seeing dolphins, manta rays, eels, octopus, and turtles. Elizabeth, who left a glowing review, described her experience: “Diving through the arch was amazing, and we loved seeing dolphins, manta rays, eels, and an octopus.” The arch itself, a popular site in Kona, offers a natural frame for memorable underwater photos.
During the winter season, whales may also be hanging out on the surface, adding a seasonal thrill to the trip. The guides’ expertise ensures that you’ll get the most out of each sighting, whether it’s a curious turtle or a passing pod of dolphins.
At $228.42 per person, this tour offers good value considering the inclusions: two guided dives, all equipment, lunch, and onboard amenities. Many reviews emphasize the professionalism of the guides and the quality of the gear, which are often two of the most important factors for divers. The fact that the company is well-established and highly rated adds confidence, especially for those new to Kona or Hawaii.
The small group size allows for more personalized attention, making it easier to ask questions or get help with gear. The timing—starting at 8:30 am—fits well into a day of exploring the Big Island, leaving the afternoon free for other adventures like visiting Volcanoes National Park or relaxing on Kona’s beaches.

The experienced guides are a major plus, making the whole experience feel safe and enjoyable, even for those who might be a little nervous. The quality of equipment and thoughtful amenities like hot showers and a light lunch elevate the trip beyond just the dives. The opportunity to see dolphins and, seasonally, humpback whales, provides that extra wow factor that many travelers remember long after their trip.
The reviews from previous participants consistently praise how well-organized and friendly the staff are, with one diver noting, “Everything felt safe and extremely well-organized from start to finish.” This reassurance is vital when booking a water-based activity in a new environment.
