I started diving with Extended Horizons several years ago. I chose them originally for convenience and somewhat lower cost. Now, I choose them for their interesting dives, professional service, marine-life knowledge, and great dives. Each year, it seems like they've become a more cohesive dive team who work hard to earn everyone's business. Two dive trips this time to Lanai... More

It's long way to cross over to the cathedral, but the extended horizon cuts through the waves without too much effort. Diving is amazing and the crew really looks after you... maybe a bit too much. If you like constant attention from your dive guides this guys will look after you, but they can easily give more information than is... More

My 18 yr old son and I did one shore dive and 2 2-tank dives off lanai with Extended Horizons. All our dive instructors did a great job. They had great focus on safety and were very knowledgable on the marine life. The dives really were focused on providing a tour of the ecosystem. They spent time on the ride... More

I had a great diving experience with Capt. Aaron, Mark, and Victoria of Extended Horizons Scuba. They deal with smaller groups (12 max) than some other dive companies in the area and I was really impressed at how they customized/adjusted their services to target all the divers of varying ability. They are very knowledgeable and Mark and Victoria are trained... More

My girlfriend and I recently went diving with Extended Horizons. They were a friendly, professional group and very accommodating for what we needed. My girlfriend was getting certified and I was just looking to do more diving. Jenna was very patient, knowledgeable and friendly, she made my girlfriend's certifcation experience that much more enjoyable. She provided tips on how to... More

Our son (13) was planning to go out on his first ocean dive since becoming a certified diver so we wanted to go with someone that would give a lot of attention to him and take their time with him. My husband and I have been certified for years. Mark met us on our first morning and immediately made our... More

Overshadowed in popularity by it's more popular sibling, Second cathedral, what the first cathedral lacks in name recognition it sure makes up for in a great dive. With a cathedral equal to or more beautiful than cathedral two, great fish life and a fun and exhilarating 'shotgun' exit this is a great dive. The Extended Horizons crew, that consisted of... More

Had an amazing dive with extended horizons and from start to finish, everything was handled with friendly professionalism-they definitely take their jobs and your safety seriously, but not themselves!! They are über Eco warriors in their whole operation and take the time to actually show you things and 'debrief' about it later! Going across the rough channel, some people did... More

We had a great time with Extended Horizons. We went on two day dives and a night dive and wished we had signed up for another day on top of that! No complaints about the gear or the boat, and only great things to say about the people who took us out (Victoria, Erik, Mark, and Jack). They were all... More
