The cheapest boat on a Kona calendar is rarely the cheapest day in the water. A low sticker often skips tax, rental gear, nitrox, and the booking fee. Two shops can look close online and finish far apart once a BCD, a regulator, and a harbor charge hit the receipt.
These kona scuba shops do different jobs. The seven operators below cover manta and night dives, beginner courses, rental and gear service, and private charters. Hawaii already runs a huge dive market. A Kona Honu Divers Hawaii diving guide puts the state at 1.5 million or more scuba dives a year across more than 215 licensed dive shops. In a field that size, the advertised number is a starting point, not the price you pay.
Each profile covers services, certifications, price signals, boats, gear, and what customers praise or criticize. I give Kona Honu Divers the longest look because it runs the broadest set of trips and the credentials you can check. The other six are judged on the same terms. Match the gaps in the listed price to the diver standing at the counter.
1. Kona Honu Divers
If you want one harbor desk for a full week, start here. Kona Honu Divers covers beginner courses, family snorkeling, reef charters, private boats, and the night trips people fly in for. Combined staff experience is more than 200 years, with over 60,000 collective dives. The shop was voted best dive operator in Kona and won the Scuba Diving Magazine Reader's Choice Award for the best dive company in the Pacific, with recognition that includes safety, staff, boats, and overall experience. The pattern is easier to see in Kona Honu Divers reviews than in a single star count.
What the Listing Leaves Off the Receipt
Custom boats carry shaded seating, padded seats, hot showers, and real storage. Rental gear is serviced before it goes aboard, and we size you for anything you reserved at check-in. We also handle the tanks and weights. Certified Enriched Air divers get free nitrox with dive packages, and early-diver discounts are advertised. There is no single public rate card for every tour, so total the cart instead of guessing from a teaser.
The Kona diving tours page puts morning reef trips next to the 2-tank manta dive and snorkel, the blackwater night dive, and the premium advanced two-tank trip. For mantas, I would pick Garden Eel Cove. It is sheltered, the viewing area is cleaner, and the reef holds up better than the more exposed alternative.
Practical rule: Book the manta night early in the trip, not on your last evening, and only if your card and recent diving match the briefing.
- Range: Courses, rentals, repairs, snorkel seats, and private charters sit with one operator.
- Night work: Manta and blackwater sit beside daylight lava arches, caves, and reefs.
- The catch: Advanced and blackwater trips need certified, current divers. Beginners train first, and you will not see every dollar until you check availability.
2. Jack’s Diving Locker
Jack's Diving Locker is the long-running full-service center, not a boat with a logo. You get boat dives, training, retail, rentals, and service, plus four dive boats and two Kona-area shops. It is a PADI 5 Star Instructor Development Center with a training pool, so a new diver and a certified buddy can stay in one building. A harbor-side shop that opens early helps when the boat leaves at dawn.
Published sample packages for eligible two-tank trips run roughly $195 to $263 per trip. That range includes taxes and fees and sits before any online booking fee. Eligible packages may take 10% off after three trips, with conditions attached. The board covers classic and advanced two-tanks, manta rays, Pelagic Magic, private charters, tank fills, and gear service.
The fine print is what matters for comparison. Prices move, the discount has eligibility rules, and the online fee can eat part of that 10%. I would pick Jack's when someone needs a course or a regulator serviced. I would not pick it only because the package looks cheaper than a bare boat seat. Details live on the Jack's Diving Locker site.
3. Big Island Divers
Big Island Divers prints a local two-tank from $179 per person. That number is before tax and rental gear. Add a BCD, regulator, and computer and the morning stops looking like a budget dive. Shop check-in is required, and hotel transportation is not offered, so your transfer is another line on the day.
The menu is wide for a Kailua-Kona shop. Morning boats and advanced trips hit lava tubes, arches, and less-visited sites. Manta night dives and blackwater are on the board, along with retail, training, on-site service, mixed dive-and-snorkel seats, and private charters. Some trip and rental prices are published, which makes the add-on math easier than a shop that hides every extra.
It fits divers, snorkelers, and private groups who want one operator and can get themselves to the shop. It fits poorly if you priced the $179 as an all-in seat. A wider look at how Kona scuba dive shops split boat work from retail helps before you compare carts. Book through Big Island Divers only after the rental line is visible.
4. Kona Diving Company
Kona Diving Company is a separate, family-run center built around smaller groups, not a second name for a bigger harbor shop. The two-tank morning charter is listed at $200, with rental gear and other add-ons priced apart. Nitrox is an add-on, and nitrox certification is offered if you do not already hold the card. The morning boat is a 46-foot Newton, with a published maximum of five divers per divemaster.
That ratio is the product. Photographers and newer certified divers get more attention than they do on a packed rail. Morning, advanced long-range, manta evening, and night-reef charters are available, plus introductory dives, referral training, a private guide, and multi-trip discounts. Shop hours are shorter than some larger operators, so a late walk-in for gear is a bad plan.
Free nitrox at another shop is not a reason to skip gas checks. A Divers Alert Network review of nearly 400 U.S. recreational fatalities found 55 nitrox divers (14%), and only one of those was considered likely to involve an oxygen-toxicity seizure. For common EAN32, the maximum operating depth at a 1.4 oxygen partial-pressure limit is about 111 feet. Confirm the analyzed mix, then read the Kona Diving Company profile and the operator site before you add the private guide.
5. Kona Shore Divers
Skip the boat if the harbor ride is the problem, or if you are rusty and want coaching at the waterline. Kona Shore Divers, based in central Kailua-Kona, specializes in guided shore diving, private days, and training from Open Water through Rescue Diver. Introductory and refresher shore dives, certified shore dives, advanced boat dives, and private snorkel experiences are all on the card.
Published starting prices include referral programs from $799 and Open Water eLearning courses from $1,172. Course pages list equipment inclusions, which is more honest than a certification teaser that bills the kit later. Listed hours are Monday through Saturday, 8 a.m. to 2 p.m. Private and small-format days book out, so confirm what the specific course includes.
Certification does not make every lava entry benign. Hawaiʻi's Division of Aquatic Resources flags Old Kona Airport for shore snorkeling and scuba, then warns of sharp coral and lava, dangerous swells and currents in summer and winter storms, and no lifeguards on duty. State snorkeling and diving rules also require a diver's flag of at least 12 by 12 inches, lit between sunset and sunrise, and you may not surface more than 100 feet from that flag except in an emergency. Use a Big Island shore-diving guide beside the Kona Shore Divers site, and cancel when the entry looks worse than the forecast.
6. Manta Ray Dives of Hawaii
Manta Ray Dives of Hawaii sells daytime two-tank dives, manta trips, and snorkeling along the Kona Coast. The published long-range trip is $270 per certified diver. Fees and gear costs vary by item, so the $270 is not a closed total. That longer day visits two sites and advertises onboard lunch and hot showers. Some outings take divers and snorkelers together.
The manta product is the reason many people book. The operator publishes a return policy if no mantas are seen, subject to the stated terms, and trips follow no-touch wildlife rules. Age, certification, and other limits apply on the long-range boat. Local two-tank days and multi-day packages sit beside the signature night.
A 2009 Hawaii legislative testimony packet put the Kona manta-diving industry at about $2.5 million a year and said mantas were seen on about 80% of dives at Garden Eel Cove. That hit rate is why site choice matters more than a slogan. I still prefer Garden Eel Cove when the plan is a night viewing, because the cove is protected and the reef gives you a better stage than a more exposed mark. Some listed prices here exclude tax, harbor fees, booking fees, or certain rental items. Read the line items on the Manta Ray Dives of Hawaii site before you treat $270 as the whole night.
7. Kohala Divers
Kohala Divers sits in Kawaihae, on the Kohala Coast, north of Kailua-Kona. That drive is the cost people forget. If you are already in Waikoloa or at a Kohala resort, the shorter road can beat a cheap Kailua-Kona sticker. If you are staying in town, the transfer eats the savings.
The two-site trip is built for mixed groups. Listed prices are $229 for certified divers, $189 for snorkelers or observers, and $110 for ride-alongs. Sites are picked for the day's conditions. Divers and snorkelers can share the outing. The shop adds retail, rentals, servicing, and air and nitrox fills, plus a free local dive club and themed dive days. Shuttle service covers select resort areas, not every hotel.
Confirm the check-in point and whether your resort is on the shuttle list. Prices change with participant type and certification, so a family of four is not four times the diver rate. I would use Kohala Divers for a north-shore mixed day, and I would stay with a Kailua-Kona boat when mantas or blackwater are the point of the trip. Start with the Kohala Divers site.

Matching Your Dive Style to the Right Kona Shop
Pick the shop by the dive you want, then rebuild the price. Manta and night boats, beginner courses, rental and repair desks, and private charters are four different purchases. Ask what the listing includes, what the group cap is, and which certification card the trip requires. Tax, gear, nitrox, and booking fees belong in that total before you pay.
A $179 reef charter that bills tanks and weights separately can land above a $200 charter that bundles them, so read the add-on column before the headline rate. The same logic applies to courses: a referral price only covers half the certification if the open water sessions are billed downstream.
For a manta night, I would book Kona Honu Divers and aim for Garden Eel Cove. The cove is protected, and the viewing area beats the busier alternative. A University of Hawaiʻi study treats crowding and support for management in Kona's manta snorkel and scuba trade as a real local issue, not a generic complaint. A sheltered site with a controlled briefing beats a cheaper boat that stacks more people on the same mark.
The Big Island has no recompression chamber. Serious decompression illness means emergency care, then evacuation to Honolulu, which is why remote, deep, repetitive, and night profiles need a conservative plan and insurance that covers evacuation, as the Kona diving guidance lays out.
We run the Kona boats, and we size rental gear at check-in. Call 808-324-4668 before you book if the total, the certification gate, or the site plan is unclear.
Kona Honu Divers runs the Kona trips this comparison keeps coming back to, from morning reef charters and training to manta nights, blackwater, and private boats, with rental gear and repairs in the same shop. If you want that range without piecing the week together from seven stickers, start with the live calendar. Visit Kona Honu Divers and match the boat to the diver, not to the lowest advertised price.
