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!

We arrived at the boat launch for the pre-trip briefing at 630a, then we returned from the 2 tank dive at 12p. 5.5-6 hours should be allocated. Have fun, it was great!
