2-Tank Adventure

Book your Adventure Now

No activity selected

We offer a more aggressive 2-tank trip geared toward divers who feel our regular charters do not fulfill their quest for adventure! These charters will most often be drift dives. This trip is offered on Sundays and Fridays and we invite experienced divers to join us for a new level of diving experience. If you are looking for more challenging dives, consider this trip! Great for experienced divers who want a shorter day than our 3-Tank Adventure trips.

Divers must:

  • Be an Open Water Certified Diver or above
  • Have been diving within the last year
  • Have a minimum of 25 lifetime dives
  • Be comfortable with a maximum depth of 130 feet and rough ocean conditions
    And of course: don’t dive and then board an aircraft or drive up Haleakala crater (the summit is over 10,000 feet).

If you do not currently qualify due to our time requirement, you can choose one of the following options:

  • Do an ocean dive at home before you arrive
  • Do a shore dive (guided or on your own) when you arrive
  • Do a 2-tank daily boat dive before your adventure charter

Sundays and Fridays: Check-in is 6:30 a.m. at the Kihei Boat Ramp. Meet your boat on her trailer at the top of the parking lot.

Message from Ed

I realized a long time ago that the quality of a dive trip is directly related to the willingness of a divemaster to listen to the diver's (your) needs, and then to go out of his/her way to give you more than you are asking.

Over the years, I have associated myself with the best professional captains and divemasters in Hawaii. The common trait you will find in each of us at Ed Robinson's Diving Adventures is that we care about the quality of the job we do, and we care about the divers we are serving. If you don't have a good day, we don't have a good day either.

Aloha! I want to thank the captain and crew of the Sea Spirit for a fantastic experience diving at Molokini at Crater. This was the first dive I've taken without my own buddy in tow, so I was hoping to find at least one friendly diver on the boat. Instead I found 3 crew that instantly felt like friends and a small group of fun loving divers who all stayed together safely as a group, guided by Ricardo who pointed out all the interesting creatures below, from sea turtle to octopus. It was like a dream and I can't wait to return to Maui for more diving. Mahalo!!

We dove with 3 different outfits in Maui. All were very good, but yours was the best. The Adventure-X trip on Wednesdays was perfect. We dive a lot at home and prefer being around advanced divers. Ed's crew handles dives perfectly: no rushing, maximum bottom time, safety. The backside of Molokini was amazing. Also, splitting the 2nd tank into two short dives was very considerate. Other operations would have burned the entire tank at one location. We'll be back!


This is my third trip to Maui and diving with Ed Robinson's diving Adventures and I LOVE IT. I probably did anywhere between 50 and 60 dives with ERDA, Molokini back and forth and along the East Coast of Maui knowing all the cool reefs, wrecks and 'secret' spots. Not only I always enjoy the 'hang loose' characters of the dive masters and boat crew, no it's like meeting friends and almost family. Been 'lured' to other dive ops around Maui but keep bouncing back to ERDA. As an enthusiastic diver, photographer and videographer it's a great pleasure to go back to the SEA DIVER and SEA SPIRIT every week. There is no better Maui diving than with Ed and his excellent crew. Mahalo and Mele Kalikimaka.
