If staying down longer and getting back into the water sooner sounds appealing, then don’t hesitate to become an enriched air diver. You’ll learn why diving with air that has a higher oxygen content gives you more bottom time, and how to properly use enriched air. You’ll learn safety concerns and best-practices, how to analyze oxygen content in your scuba tank, and how to properly set your dive computer for enriched air.

Prerequisites

If you’re at least 12 years old and have your Open Water Diver certification, you may enroll in the Enriched Air Diver Specialty course.

Manta Ray Night Dive

What a truly amazing experience!! Nearly an hour of down time with dozens of large mantas putting on an incredible show. Jenna, and Captain Kevin made it a pleasant and safe trip. This is a must do while staying on the Big Island.

One of the Top 10 Dives in the World!

Believe It, it really is one of the most phenomenal dives we have ever done! Laying on our stomachs on the ocean floor around the "campfire" was unforgettable as the beautifully graceful Manta Rays soared directly above our heads, over and over. They performed ballet moves with each other, sometimes as many as 4 at a time feeding on the plankton.

Excellent

We have been diving the BID on multiple dives over multiple trips and we keep coming back to them because of the high quality service that they provide. Definitely a step above the usual dive shops.

Manta Night Dive Lives Up to the Hype

I recently went on the sunset reef dive & manta ray night dive. I was a little hesitant about my expectations because I heard so many great things and didn't want to be disappointed. Cannot say enough great things about the company, captain and DM - highly recommend and will dive with them again.

Excellent Staff

We had a great two tank dive with BID last week! Our dive master Amy was excellent all the way around and our captain Rob was not only a great captain but very knowledgeable about Hawaii and even served hot chocolate on the way back to the Marina.

Incredible

It was so amazing that it made me feel like a kid again - this is coming from someone who has traveled a lot. I talked to other divers who described the Black Water Dive, and I wish I would have done that one instead of the twilight dive.

Great Dive Experience

Great dive experience underwater and while on the boat. Experienced staff gave all of the direction and assistance needed but did not "over-guide" the trip as is often the case.

An Amazing Souvenir

I booked the night Manta Ray snorkeling tour. It was simply awesome. In addition of the amazing experience to observe the Manta rays in their natural environment, the crew was just perfect, always helpful and offers us a warm hospitality. I definitely recommend this tour.

Two Tank Dive

This is the dive shop to go with for great service and knowledgeable staff. I went out for a refresher dive since it had been 9 years since my last dive. Becca was great and by the end of the second dive I felt comfortable being back in the water.
