Bob's Hawaii Adventure - BOB Underwater Adventure

Enjoy a fun ride on an underwater scooter and see Oahu’s fascinating marine life up close. While sitting comfortably on a seat of a submersible scooter, your head will be in a clear acrylic Breathing Observation Bubble (or BOB for short), which is filled with air from a storage tank. The scooter is powered by a thrust motor that can reach a top speed of 2.5 knots. No scuba diving experience is necessary. The underwater scooter is easy to operate and also gets you away from the constraints of traditional scuba gear.

The tour begins at the Koko Marina Shopping Center in Hawaii Kai. After a short orientation session that includes complimentary coffee and tea, you will board the shuttle boat and cruise out to Maunalua Bay. A group of three people will submerge at one time, and a master diver will accompany and guide you. After the BOB adventure, you are free to swim or snorkel in the beautiful Maunalua Bay.

Tour Highlights

  • Fun ride on an underwater scooter
  • See plenty of tropical fish
  • Short ride on a shuttle vessel – great photo opportunities of Oahu’s scenic south shore
