We had an outstanding experience with Extended Horizons, led by divemaster Gustavo "Gu." Recent Maui rains reduced visibility at many sites, but Gu adjusted the plan and guided us to the best possible conditions. That made the difference. These were refresher dives for our group, and Gu handled them exactly right. He quickly assessed each diver's experience, our small group included both newer divers with fewer than ten dives and others with more than 70, but with time since our last dives. His review of fundamentals, safety, and buoyancy control was clear and structured, without slowing the group down. He also reinforced reef etiquette and respect for marine life in a practical, no-nonsense way. This team takes responsible diving seriously. What stood out most was Gu's site knowledge. Not just which sites to choose, but where to position within each site to maximize visibility and encounters. He set expectations on what we might see, spotted eagle rays, green sea turtles, white-tip reef sharks, snowflake moray eels, and more, and then delivered. We saw all of it. With two divers carrying cameras, he was mindful of positioning, and I came away with great shots of eagle rays, reef sharks, and multiple turtles. The highlight was a turtle cleaning station at Mala Wharf, with six turtles active at once and eagle rays passing nearby. It was one of those rare dives where something meaningful is happening in every direction. The attached photo captures that exact moment, multiple turtles gathered at the cleaning station with eagle rays moving through the scene. Operationally, everything was tight: * Strong safety culture and clear briefings * Efficient check-in and gear handling * Well-maintained equipment * Good pacing, no rushing, no wasted time * Attentive in-water supervision without being intrusive * Effective group management for mixed experience levels If you are traveling to Hawaii with limited dive windows, this is the operator you want. They remove uncertainty and maximize your chances of a memorable dive. Highly recommend Extended Horizons, and Gu as your guide. read more

Extended Horizons Scuba - Turtle cleaning station at Mala Wharf. Thanks Gu for pointing this out!! - Diving Near Me - Lahaina, Hawaii

We absolutely loved our experience diving with Gu and Ty!! We were a little rusty, but Gu reviewed everything with us and we felt completely comfortable. He also prepped us with details about the animals we were likely to see and fun info about their behaviors so we knew what to look for - we saw rays, turtles, moray eels, and an octopus! We did two shore dives at Airport Beach and the team did a great job of adjusting the plan given some areas of reduced visibility after the recent severe storm, so we still had an amazing experience. Gu knew every detail of the reef so knew exactly where to take us. Everyone we interacted with including the instructors and the people we spoke to about scheduling were kind, flexible, and informative. We hear they'll have their boat up and running this summer - when we come back to Maui we will definitely sign up for another dive with this crew!! read more

Phenomenal Dive Experience with Extended Horizons! We booked our scuba diving excursion through The Ritz-Carlton, Kapalua, and could not have been happier with the experience provided by Extended Horizons. As newly certified divers, we were a bit nervous going into our first post-certification dive, but our Dive Master, Michael, made it an absolutely incredible and comfortable experience from start to finish. Michael was punctual, professional, and incredibly charismatic. He struck the perfect balance between being instructive and encouraging, offering helpful tips to improve our diving without ever making us feel overwhelmed. He really listened to what we were hoping to get out of the dive and tailored the experience to match. We did a two-tank shore entry dive, and it was spectacular. Michael guided us to some amazing marine life--green sea turtles, moray eels, cone snails, sea urchins, and even three stunning green lion fish. His deep knowledge and passion for the ocean were clear throughout, and it made the entire dive even more memorable. We can't recommend Extended Horizons enough--especially if you're a beginner looking for a patient, supportive, and fun dive guide. Thank you, Michael! We'll definitely be back. read more

My son and I had a great experience with Extended Horizons last week. We decided to go diving last minute and Eric (owner) was very hands on helping us get everything set up for a beach dive. I've been certified for years but it's been a few years and this was my sons first dive. Our instructor Michael was knowledgeable, thorough, and patient while we oriented ourselves with the equipment and made our initial decent beneath the surface. Unfortunately visibility wasn't great and the current had us working harder than I would have liked, but it still turned out to be a great day! What really impressed me is the service I received after the dive. I reached out to Eric to thank him for his help and let him know about the conditions and he took the time to listen and sincerely shared in our excitement. We've been lucky enough to travel to Maui a few times and I've been diving every time, but sharing this experience with my son made it the best dive yet. The experience and professionalism Extended Horizons brought to the beach that day allowed us to enjoy the dive without any stress or concerns. I can't imaging a better way for my son to make his first dive! When it comes time for my other kids to try diving, Eric will be my first call. I feel it's important to point out that I was not asked to post a review. The last two companies I went diving with in Maui offered me a discount on my next dive if I post a positive review. Eric and his team are the real deal and earned all the positive reviews including this one. Thank you Eric, Michael, and Extended Horizons! read more

I can't say enough great things about this dive shop and its amazing team. Michael South was an exceptional instructor; patient, knowledgeable, and genuinely supportive throughout my Open Water Certification. He didn't just guide me through the course, he became a true friend in the water. The entire team, including Erik and Victoria, went above and beyond to ensure everything ran smoothly. Thanks to their dedication, I finished my certification feeling confident and even got to squeeze in an extra day of diving in one of the most beautiful spots on Maui! This is a shop worth supporting, especially as they work to rebuild after the fires and prepare to launch their own dive boat. The passion, professionalism, and aloha spirit here are unmatched. Highly recommend! read more

Or dive instructor, Michael, was great at explaining and demonstrating the skills that we would be executing in the water for the PADI advanced open water diver course. The locations for each dive were excellent and the specifics were thoroughly explained beforehand. I've gone diving with Extended Horizons in the past and I'm happy that survived the fires and have resulted their amazing work, providing excellent experiences for visitors and giving back to the local community as well. read more

Hey people. This team is fully operating despite the Maui fire. Great experience doing a couple of shore dives with Gu as our guide. Everything we needed was right there on their truck. Very educational to learn about the many types of fish we saw including eagle rays, moray and barracuda. We couldn't see them, but could hear the humpback whales read more

Michael was an amazing PADI instructor. We did our four PADI certification open water dives and it was an amazing experience. Thank you for your wonderful guidance. We are 66 and 67 and got certified!!! Woot woot !!! read more

Great outfit! We had a great diving experience with the Extended Horizons team and can honestly recommend them. read more

Eric (owner) was extremely patient with me as we tried to unravel my certification with PADI. The result was a single tank dive with Mike. The instructions that he gave me were clear and precise and the dive was a great introduction to Hawaii diving. Sadly, they lost the Shop and Boat, but are on the way to rebuild the business. I look forward to diving with them again in the future Rick S read more

Our family recently did our open water course to get certified with Extended Horizons. They were so accommodating and understanding since we all couldn't do it at the same time. Our dive master, Phil was so patient with me and got me through the first day when I wanted to quit (long story). Our kids dive master was Bruce and he was great with our kids! They were both we very knowledgeable, patient, and thorough. We highly, highly recommend this business and am extremely satisfied. read more

My very first diving experience and Michael was fantastic! Made me feel comfortable, took his time with me getting used to being underwater, and was more than a 5 star experience! Don't even waste your time going anywhere else. It's worth every penny and was an experience I will always remember! Thank you Michael for the attentiveness and care you took with me during our dive! Mahalo! read more

Such a great dive company. Love diving with them when I visit Maui. For the last 2 years, my dive master was Gabi, and she's awesome. I love how attentive she is & how proactive she is while on the dive to make sure I see all the wildlife. She takes a ton of time to write down names of the different animals & pointing them out. I particularly love how curious she is, exploring & poking & looking around even more than me! Can't wait to return. read more

I had a great time finishing up my PADI Open Water scuba certification! Michael South was an amazing instructor and very clearly explained everything I needed to know while also making the experience incredibly fun and rewarding in and of itself. Hope to see Michael and everyone else at Extended Horizons again in the future! read more

Three standouts of exceptional service: 1. Direct attention while trying to schedule and assist in PADI referral, even over the weekend. 2. Michael, my instructor, was exceptional. Practical, detailed, personable, and just a nice guy. 3. The business was focused on my enjoyment but also leaning so I could certify. That's the whole point. I would highly recommend Extended Horizons. read more

Had an amazing time diving with Michael! He was an awesome and fun instructor and guide and we saw some amazing sea life! My favorite part of visiting Hawaii for sure! read more

Refresher... I'm a Certified diver but I didn't dived in 10 years!! Because of all their reviews on here I decided that Extended Horizon is an excellent company to refresh my memory, because honestly I was nervous!!! From the start The lady in their office was super friendly and very professional! I scheduled 3 days after to go with an instructor. I met with Gustavo and he was so chill and so patient that I knew it going to be fun! Everything he said was very clear and I could tell he really loves what he do and loves to teach! Anyway Gustavo was amazing and my diving experience was just wowwww! I couldn't stop smelling and he promised sea turtles and he delivered!! Seeing those creatures swimming just made my vacation! Thank you Gustavo! Ask for him as your instructor!! read more

Extended Horizons Scuba - Me with sea turtles!!! Thank you - Diving Near Me - Lahaina, Hawaii

We had six amazing dives with Michael S of Extended Horizons. First four were open water certification for my teenager, and we had such a good experience that we booked two dives once the certification was done. Michael is a great instructor, super knowledgeable about sea life and fun to hang out with. We saw at least a dozen of turtles, half a dozen white tip sharks and an untold variety of fish, all of which Michael named for us in real time during the dives, writing on his handy tablet. On land, great advice on drying up waterlogged ears and getting rid of that pesky mask fog. Recommending Michael and the shop without reservations! read more

Captain Aarika, Ashley and Victoria were one word...FANTASTIC!!! These gals know how to make everyone feel welcome, run a well-oiled machine. Ask all the right questions and answer any questions their guests may have. The day we went out Maui and Mother Nature blesses us with whales, dolphins, a shark, oodles of fish and calm, clear water. This will be my go-to dive company now as long as these ladies are there! Keep up the fantastic work, I appreciate what you are doing! Box Fish Trish read more

Went on 4 different shore dives with Gabi and she was excellent! Very friendly, professional and safety oriented and man can she find some interesting things down there. There's no way I would have found Harlequin shrimp, pipefish or the nudibranchs she found while guiding me and one other diver through some spectacular sites. Blackrock is a must do! Had an inquisitive turtle swim up and almost high five me! Hopefully we'll get to Mala Pier on our next trip! Had to change sites due to swell and current conditions. read more

I did my 4 open water referral dives with Gu from Extended Horizons, and my friend did their own dive on one day and joined me for both dives the 2nd day (dives 3/4). I can't say enough nice things about my experience with the owners, my instructor Gu, and the dives themselves. We did shore dives since their boat was docked for periodic maintenance and had a blast at Mala pier and old airport beach. Gu was outstanding in his clarify of skill checks for the referral and at making sure we saw everything possible diving, he was amazing at finding tiny nudibranch, eel, and all sorts of creatures. We saw a TON of turtles at Mala and strongly recommend checking it out, there were whitetip sharks just chilling, plenty of swim throughs, frog fish, eels, and lots of other critters. I was coming in with SDI certs and Extended Horizons is a PADI shop, they made sure to cover all my SDI skills and added in the PADI things they thought would help out in the long term. If I'm ever back in Maui I'll definitely dive with Extended Horizons again! read more

Great dive once more. Gabi was a wonderful guide and provided hints to make us better divers and lots of details about the animal life. read more

Extended Horizons Scuba - Diving Near Me - Lahaina, Hawaii

Dive Master Rachel was AWESOME - helped get us set up (brand new gear since Lahaina fire), then helping us in/out of the water through some moderate shore break at Kahekili Beach Park just north of Kaanapali She pointed out a rare 'Strawberry' Nudibranch, juvenile Parrot Fish and Wrasse' and led us (and one other diver) on a very good shore dive given the conditions. We've always enjoyed our many boat dives with Extended Horizons, and will dive with them again on our next visit to Maui. read more

We had two fantastic dives near Lanai with this scuba group. We loved our instructor Shelby. She was incredibly informed and wonderful at finding sea creatures. We particularly loved the dive site Second Cathedral, but Secret Cove was breathtaking as well. I have dove with many scuba groups and would highly recommend this group. They provide a truly top notch experience! read more

I last used EH about ten years ago so now I'm back on Maui after quite a gap I called them up and got an intro Shore dive booked immediately as I was a bit rusty. they were very good, just three of us on this dive on a small reef at Kaanapali beach and two dive masters Brad and Gabby. gabby escorted me around pointing out all sorts of stuff I missed and took care of me. if I have the time I'll use again maybe for Cathedrals which I did a looong time ago. definitely to be recommended esp if in the Lahaina area. note that google maps doesn't seem to know where they are, look for Unit A on the right just after you turn into their road. read more

It was my first ever scuba diving experience and I loved it! Scarred at first when got underwater, I was reminded by our wonderful instructors Emma and Maya to "just breathe" :) and I was able to get over it and enjoy the underwater world. Ladies were great, friendly and attentive to everyone in our large group. It's just wonderful to have two women as instructors! Thank you read more

Best guided dives I've ever had. Gabi was amazing and so informative. We had the best time. These were 2 shore dives in Kaanapali area and everything went extremely smooth and the weather and water temps were awesome. Gabi not only pointed out the marine life but also used an underwater etch a sketch to write out the names of marine life. Thanks for the wonderful experience. read more

This is our second time diving with Extended Horizons. we did our first open water dives with them back in 2008 and decided to go shore diving with them again yesterday. They have a great online booking system that allows you to sign waivers etc before the dive which saves time on the day of. Due to poor visibility at other locations, we did two dives at airport beach. Both were about 50 minutes and though the vis wasn't great, we still saw multiple turtles, eels, Slipper Lobster and a ton of fish. One thing to note: Their dive shop / boat storage is neat and organized and they obviously take pride in their equipment and property, which in my mind speaks volumes about their professionalism. We plan on diving with them again in two days. If you are considering diving in the Lahaina / Kaanipali area, I highly recommend them. read more

I've always had a fantastic time diving with Extended Horizons and this trip we booked a Discover Scuba dive for two uncertified divers in our group. Not only did Extended Horizons do a fantastic job of preparing and guiding the two uncertified divers, but they also fit us in last minute while dealing with the boat in drydock. Four of us went on the dive (two certified and two uncertified) along with the two guides from Extended Horizons. Everyone had an absolute blast. Can't wait to come back and dive with Extended Horizons again. read more

Fantastic service!! Gu was my guide and he did a great job at showing the fish underwater. I felt totally safe and comfortable as this was my first time diving in a few years due to the pandemic. I did the twighlight dive. I definitely recommend Gu and Extended Horizons Scuba for a great dive!! read more

Gabi is a first rate instructor and guide. Her knowledge of marine life exceeds expectations.

My brother and I had been referred to Extended Horizons from a local dive shop back in California. We were on a tight schedule due to our vacation plans but Extended Horizons was able to get us set up with a great 2 Tank Shore dive. Included in our pricing was rental gear as well. We arrived at the shop and all of the staff was great. We were introduced to Hannah who would be our guide for the day and she was wonderful. She got us situated with gear. We went over our experience and what we wanted to do/ see for the day. We loaded up and met her at Kahekili Beach Park for dive #1. Since this was my first dive after being certified she recommended we dive here for it's easy entry and overall conditions. We found out that Hannah has a degree in Marine Biology and would dive with a small scribble pad. During our dive she was able to point out every fish, sea animal and interesting thing letting us know what it was. She was also very helpful in offering tips and pointers during the dive. Wrapping up there we headed to Mala Pier and that's where we had a lot of fun. She knew everywhere to go and explore finding us all kinds of fish and turtles to enjoy. 10/10 would highly recommend Extended Horizons to anyone for a great Dive experience! Thank you again Hannah! read more
