Both my sisters got certified on a dive here via referral on their 4 open water dives. I joined on their second dive and it was amazing. Bill is definitely an interesting person and you can tell that he just loves nature. According to my sister, he has over 9000 dives and is a great instructor.
When I joined, I had no issues with renting from them, but the craziest thing was that Bill was showing that he had trained a couple of fish on the reef he frequented that he was able to summon by clanging 2 rocks together! And he was showing off the coral that he helped grow around the area.
I loved listening

The lady shop staff is very nice and accommodating. However, the dive instructor is a very grumpy old guy and not too nice. He doesn't have a dive plan which is very necessary for a dive especially for tourists new to the area. Good thing I was an advanced diver so I know what I was doing. He tells you your bad behavior during the dive in a unprofessional manner. Constructive criticism are good if it was addressed in a polite and professional way. The dive experience was amazing but how he treats a customer is unacceptable. Future divers, you judge.

Really enjoyed our discovery scuba here. Bill was a great teacher and the water was very clear. Wish it was longer.

My girlfriend and I took a shore dive with this dive center, and Bill was our dive master. Bill was awesome and you can feel his true love to nature as well as scuba diving when chatting with him. He gave us very useful suggestions and demos, and corrected mu girlfriend’s several bad behaviors. Hope we can dive with Bill more in the future. The rental gear provided by this shop, especially fins, are admittedly a bit old. However their tour as well as rental gear price is not expensive. The lady in the front desk as well as Bill are very nice people. I enjoyed my experience there.

Bill is the most professional and experienced instructor I have ever had a chance meet !
He loves the ocean and that makes him so much more passionate about the whole underwater experience!
His wife is the sweetest and most customer friendly person to help you with all the paperwork!!
Amazing people!
And out of all 10 dive centers I called on the big Island of Hawaii this is the one you should go to!

Absolutely the greatest Dive Master ever and a local legend, he has trained and certified over 2400 people out of this very shop since 1982. He has been a part of many underwater movies and has even logged over 30 dives overtop active lava!!! Experience in the water is key to being taught well, and Bill is just the man for this. With his wisdom and years of experience he makes learning any underwater task just a breeze to figure out, since he has seen it all he knows how to correct your movements and reactions before your even do them. A true master in his field and happy to share his love of it

Amazingly personable and helpful shop owner! Snorkeling gear is a steal at $6 a day. Bill even gave us a bag of home grown tangerines. The old-school authenticity here definitely lifted our spirits after the tourist-eating town of Volcano.

Great, absolutely great!
I gave them a call in the afternoon and asked if they did any dives the same afternoon and an hour later I was on the way with Bill. He is an awesome guy, comes across as a bit grumpy at first but that only lasts for a minute. Had a great time with him and good chats on the way to/from and in between the two dives we did. He knows his stuff and is very much into marine conservation. Diving with him was very enjoyable and relaxing. Would definitely go back!!!

Got my OW training here. Shop was efficient and I did the online course in my down time. Bill is great and cares about the Ocean and the environment. Just watch him pick up trash in and out of the ocean anywhere he goes. May come off as a little Salty at first but don't let that fool you he is a great guy with tons of experience and isn't going to waste you time or his. No BS and gets right to the point but is patient and helpful. I'll be back for sure. All equipment was well maintained and not over priced.
