Maui Extended Horizons Scuba offers tours and lessons on Maui and Lanai....

Maui Extended Horizons Scuba offers tours and lessons on Maui and Lanai. Established in 1983, we are unique because our instructor/guides have extensive environmental training, we are the only commercial boat on Maui running on 100% biodiesel, We are the only dive shop running on 100% solar, and we helped found and fund the Day Use Mooring Program on Maui which prevents anchor damage and creates and maintains moorings for the State of Hawaii for the public and private sector. And we love diving!

My wife's first dive post certification and she loved it. As did I. Very professional group, educational and eco sensitive. I have been diving twenty years and this dive company is very well run and I can't wait to go back. The huge pod of spinner dolphins on the way back was an amazing way to finish the day. Highly...

We booked a shore dive with this place. It was my first official open water dive post certification and man I could not have picked a better place! The dive master was beyond excellent and knew his stuff! He reviewed the equipment with us and made sure we knew what we were doing before the journey started. During the dive... More

From the moment I booked my trip, to my arrival at the boat and until I stepped off the boat, I thought the staff was some of the most professional and friendly I have ever encountered. I went on 4 dives with this company and enjoyed every one. I would highly recommend them!

This was my first time diving with Extended Horizons and I will definitely use them every time I go to Maui. They are true professionals and I love their environmental practices from running on biofuel to handing out reusable drinking bottles. The guides are naturalists as well and seek out the cool little critters instead of just floating along. We... More

We chose Extended Horizons for one of our "refresher dives" off of Mala Pier (one of our favorite dive spots on Maui -- 35 ft on average for extended bottom time and lots of turtles and sharks). Our divemaster, Allan, was excellent and tolerated a very rookie error on my part. (During my descent, I kept hitting my inflate button... More

Extended Horizons is by far the best dive operation on Maui. I have gone diving with them in the past and the experience was so great I'm proud to say I dive with them exclusively every time I visit. The crew are extremely friendly and are all trained naturalists which means you get to see some really cool stuff while... More

I recently completed a two tank dive with Extended Horizons in early April and the entire experience was excellent! Here's the short version: 5 stars, you should dive with them!
