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!

3 staff members were very attentive to our needs and very informative of the fish and wildlife that we saw. Also stopped to see whales on the way to and from the dive sites. Snacks and individual water bottles were provide. Fresh water tank for cameras and defogger was put in each mask before each dive.

Great trip to Lanai with Raquel, Mike, Ashley and Allan. Mike was the most knowledgeable dive guide I have had in 17 years of diving but best of all, the entire crew seemed to be having fun and enjoyed having us aboard. For my daughter's first boat dive, it was a great experience!

Excellent company!!!! I've dove all over the world and this is one of the top dive shops. The crew was professional and great. The dive masters are naturalists and take the time to make sure you understand and appreciate what your seeing. I was a bit sea sick and the dive masters and crew did everything they could to make...

I had read a few reviews prior to gong on a dive with this company. I can say that i did not experience anything but a positive experience. The crew was excellent. The first dive site we went to was tested for safety prior and determined to be unsafe so we were taken to another site. So any concerns (after... More

We did a two tank dive to 1st Cathedral and another site off the shores of Lanai. The captain and crew were very friendly (1-18-16) and fun. The captain stopped the boat on the way to the dive site so we could watch humpback whales breaching! The two dive masters where very knowledgable and patient with the less experienced divers...
