If you’re planning to explore the underwater world on the Big Island of Hawaii, a Pool Scuba Refresher might be just what you need. This short, two-hour session is designed to help you get comfortable with your diving skills again—whether you’re returning after a break or just want a quick confidence boost before hitting the ocean.
What we really like about this experience is that it’s run by Jacks Diving Locker, the only shop on the island with a dedicated training pool. Plus, the pool features a window where family and friends can watch you underwater, which is a fun touch. On the flip side, it’s a relatively short activity, so if you’re after a full-day adventure, this probably won’t fill that need. But if safety and familiarity are your priorities, this refresher is a smart choice, especially for those planning to do boat trips or shore dives.
This tour suits travelers who are a bit rusty with their scuba skills, or those who just want to brush up before a bigger dive. It’s also good if you’re feeling a little unsure after limited recent experience. And because the maximum group size is just 8 people, you’ll get a more personalized and relaxed atmosphere.

Why the Pool Scuba Refresher Might Be a Good Fit
We loved the way this experience centers around safety and comfort. For many travelers, there’s a certain anxiety about jumping back into the water after a hiatus, or even just feeling a bit uncertain after a challenging past experience. This refresher gives you the chance to refamiliarize yourself with your gear and practice core skills like mask clearing and regulator recovery in a controlled environment.
The fact that Jacks Diving Locker is the only shop on the island with a dedicated training pool** is a big plus. It means your session isn’t rushed or squeezed into a busy open-water schedule. Instead, you get to focus on yourself and your skills, which can significantly boost your confidence once you’re back in the ocean.
The pool’s feature of a window for spectators earns some extra points. If you’re traveling with family or friends, they get to watch you underwater, which can be a fun and reassuring element—plus, it’s a great photo opportunity.

What to Expect During the Session

The meeting point is conveniently located at Jack’s Diving Locker in Kailua-Kona, starting promptly at 10:00 am. The experience is designed to be straightforward: you’ll spend about two hours in the pool, working on key diving skills in a safe environment.
Once you arrive, you’ll be greeted and briefed by the instructors. The focus is on refreshing skills such as mask clearing, regulator recovery, and buoyancy control. Even if you’re an experienced diver, this session helps to prevent common issues that can arise from rusty skills or past difficulty.
The pool itself is equipped with a large viewing window—something that truly sets this apart from typical refresher courses. Watching from outside, loved ones get a glimpse of your underwater practice, adding a fun, communal element to the experience.
Expect a relaxed pace, where you can ask questions, redo skills if needed, and regain your confidence. Because the class size is limited to 8, you won’t feel rushed, and the instructors can give personalized feedback.
The Value of a Short Refresher

At $100, this session is reasonably priced considering the personalized instruction and the unique pool feature. It’s a manageable investment before spending time in the ocean, especially if you’re planning on boat trips or shore dives. The goal isn’t to become a pro in two hours but to leave with greater comfort and safety, reducing the risk of stress or mishaps during your dives.
One reviewer shared, “Jacks diving is the best!!! We had a super tight window as we were flying to the big island that day, and wanted to do the Manta Ray Night dive. I had to do a refresher course after a few years, and it was perfect.” That kind of flexibility and efficiency really makes this appealing for travelers with packed schedules.
Practical Details and Logistics

The tour begins at 10:00 am at the Jack’s Diving Locker shop, located at 75-5813 Alii Dr, Kailua-Kona. The activity lasts approximately two hours, making it easy to slot into a morning or early afternoon itinerary.
Booking is simple and usually done at least nine days in advance, with the option for free cancellation up to 24 hours before the scheduled start. This means if weather turns sour or plans change, you won’t lose your money.
The tour is suitable for individuals with moderate physical fitness and allows service animals. The group size is capped at 8, ensuring a more relaxed setting. Because of the safety focus, this experience is generally suitable for confident swimmers or those with some basic comfort in water—it’s not specifically family-oriented but accessible enough for most adult travelers.
Real Traveler Insights
From the single review available, we see how valuable this refresher can be. The reviewer noted, “We had a super tight window and just wanted the refresher to do the Manta Ray Night dive. It was perfect for that.” This highlights how flexible and practical the experience is for travelers with limited time or specific dive plans.
Another positive aspect is the personal attention you’re likely to get with such small groups. It’s not a big class where you’re just another number. Instead, you’re encouraged to practice skills until you feel comfortable, which can make all the difference when you’re in the water.
This Pool Scuba Refresher is ideal for travelers who want to boost their confidence before ocean diving, especially if they haven’t dived recently or had a less-than-stellar experience in the past. It’s also perfect for those on a tight schedule who want a quick, effective way to prepare.
If you’re a seasoned diver, it’s still a valuable way to brush up on core skills in a safe environment. Families or friends can enjoy watching from the pool window, making it a fun, inclusive experience.
However, if you’re looking for a full-day diving adventure or a guided tour in the ocean, this isn’t the right fit. It’s purely a skill refresher, not a comprehensive dive trip.
