Brad is the only reason this review contains anything positive…read more We rented four tanks and weights during unsettled weather. Brad handled the situation exactly as a dive professional should. He checked certifications, discussed conditions, made sure we understood the risks, and confirmed we were prepared to abort the dive if conditions were unsafe. Professional, responsible, and respectful. Then there was Tina Davis. She was rude, dismissive, condescending, and openly unpleasant. I also heard the way she spoke about other customers when they were not present. Based on what I personally witnessed, this went beyond bad customer service. In scuba diving, attitude can become a safety issue. Divers must feel comfortable asking questions, raising equipment concerns, questioning conditions, and saying they are not comfortable. An employee who makes customers feel stupid or unwelcome for doing that can discourage exactly the communication that keeps people safe. I would not personally trust Tina Davis in a safety-critical interaction after what I witnessed. I also personally heard her make a comment to the effect of, "just take it from the lost and found." I am not accusing her of stealing anything. I am stating what I personally heard, and I found the comment inappropriate and concerning for someone working in a business trusted with customers' equipment and property. The contrast with Brad was dramatic. He handled the same circumstances professionally and treated us like adults. Afterward, I spoke with other local divers who described similar negative experiences with Tina. I cannot independently verify their experiences, so they can speak for themselves. I can only speak for mine. I believe management should seriously consider whether Tina Davis should continue representing this business. If this were my company, I would terminate her employment. I have also submitted these concerns to PADI Quality Management / Quality Assurance for independent review. For the avoidance of doubt, this review also puts management and ownership on notice of the safety and judgment concerns I personally observed. If a future incident involves similar conduct, ignored diver concerns, or unsafe shortcuts, I would be willing to testify truthfully under oath about what I personally witnessed, heard, and reported here. Brad deserves recognition. Tina Davis is the reason this review is one star.

What a fabulous time we had with Liquid Cosmos Divers! They have a state-of-the-art diving boat,…read moredeep expertise in scuba diving and marine biology, and are such gracious and welcoming hosts. Not to mention their homemade muffins made with Hawaiian apple-bananas are unbelievable! We had the most magical experience with wild octopuses, and so many beautiful fish and other sea creatures. It was an unforgettable experience. I couldn't recommend this family-run company more highly.

Our experience diving with Liquid Cosmos Divers was simply fantastic. This was my family's first…read moretime diving off the Kohala Coast of the Big Island, and we picked Liquid Cosmos Divers because of Mike, Jess and their purposely built dive boat named "Moonshine." Scheduling the three days of diving with Mike and Liquid Cosmos Divers was very easy and Mike kept in contact with us through the entire process. We met Mike and Jess at the boat ramp, which was easy to find with ample free parking. Their boat is very clean and you can tell that Mike and Jess put a lot of time and thought into the design to make it comfortable and very safe for diving. Although Mike offered to put our equipment together, he had no problems letting us put the equipment on the aluminum 80 cylinders filled to the rated pressure with Nitrox. Before leaving the harbor, Mike conducted a concise safety briefing. During this briefing, my family could tell that diver safety and comfort were very important to both Jess and Mike. As we got close to the dive site, Jess did an amazing job describing the types of animals we might see at the site and how to recognize them. Underwater Jess used an erasable slate to write information about the animals we were seeing and why they were important. My 14 year old son loves learning about the marine environment and Jess taught him so much in the three days of diving. Jess is an amazing dive guide and dive professional and my family and I loved diving with her. Although I cannot predict future dive or sea state conditions, in June of 2026, we had calm seas, 80 to 90 feet of visibility and warm water temps between 77 and 78 degrees. We saw dolphins, sharks, puffer fish, several rare or endemic species of reef fish, multiple eels, nudibrachs, and schools of barracuda. The coral was in great condition and Mike and Jess took us to a location that had coral for as far as we could see. Mike is a great boat captain, diver and water guy and placed us directly on each dive site and then safely picked us up. The boat has prop guards, which made me as a father happy, and a warm water shower that made my wife very happy. Between dives, Mike brought out apple bananas, papayas grown by his house, and vegan muffins that were very tasty, while Jess conducted a comprehensive debrief on what we saw during the dive. I could tell that being friends with the environment was very important to Mike and Jess and no trash or waste was ever thrown overboard. Mike and Jess make sure each diver has their own stainless steel water bottle to keep waste to a minimum and to keep the divers hydrated. The boat has plenty of dry storage, plenty of shade for the divers, and a ladder that is easy to climb. When my family returns to Hawaii we will definitely be going back out with Liquid Cosmos Divers.

They made us feel right at home from the minute we stepped on the boat. We had a fish on within the first 20 minutes and ended the trip catching seven fish! We've been on many fishing trips all over the country, and Captain Greg and Zac truly stand out. They don't just take you fishing they make the entire day a true experience and one that makes you want to come back again. We highly recommend Siren Sportfishing and will absolutely be back! Mahalo

We especially enjoyed our conversations with Captain Ryan and the bits of Big Island history he shared, and his signature banana bread was to die for!!! Captain Chad's skill in navigating challenging waters at night also gave us great peace of mind. Most importantly, special shout out to Yuta!!! He expertly and calmly guided us in snorkeling during the day and at night. We were able to see many incredible creatures while feeling safe since many of us are not used to swim in Pacific Ocean's powerful waves. PS. Beware of seasickness - take appropriate meds and have extra in hand just in case.

Feb 2026 - Based on my experience, I urge you to consider not doing business with this company…read more They appear to value revenue over the safety and comfort of their customers. Due to hazardous weather conditions, the tour we were on should never have left the harbor. Not only were the ocean wave conditions reported by the coast guard to be clearly dangerous, the driving hard rain made the conditions completely unacceptable not only for safety reasons but for customer comfort. Despite my several attempts to point this out to the staff answering the phone one day prior to the tour as well as the captain of the boat prior to departure, they blocked my attempts to reschedule or refund the trip in spite of coast guard and national weather service small craft warnings, beach closures and other tour operators canceling their tours under the same conditions. After waves broke over the bow of this small craft, the captain aborted the tour and turned around. After an unusually leisurely return to the dock, I called and asked for a refund. Later we were told based on our return time, we had received the full tour and a refund would not be issued. After escalating our concern, a senior member of the company emailed us and said we would be issued a full refund. Over six weeks later they have still not issued us a refund. We had to file a dispute with our credit card company.

Unfortunately, I can't review the actual tour, since we didn't get to take it due to a bit of a…read morerare swell in the ocean. What I can review is the communication with the company, or, rather, lack thereof. From the time that I booked the tour in October of 2019 throug our scheduled tour time in December of 2019, I made multiple attempts, through email and by phone, to contact the company for a couple of questions. None of my emails were ever replied to and none of my calls were ever returned. The most upsetting of all was the day of our scheduled tour. We were staying on Hilo side of the island, which meant that we had to get up and ready to leave our accommodations at 6a to get to the meeting spot by 7:30. We arrived around 7:45, waited til 8 for our crew to arrive. No one did. I emailed and called to get a response. Neither of which were answered at all (still 24 hours later, at the time of this review). After talking with a people that were there, it was obvious that the tour had been canceled for the ocean conditions. What is not understandable is why we were never given the courtesy of notification that it had been canceled prior to us making the drive over. The only communication we received was a email reminder of our scheduled tour the day before. And just got an email saying "thanks for joining us, please post a review " Looks like the only communication from this company is automated response...
