For divers interested in Kona’s more advanced dive sites, locally or further away, join Jack’s Diving Locker for the Advanced 2 tank boat diving trip. These trips may include deep diving in underwater canyons, descending upon huge pinnacles that rise from the ocean floor, penetrating mysterious lava caverns, or drift diving over unspoiled terrain. With fewer divers, longer time, extra food on the long range trips, and a friendly professional crew, this exciting day of diving is filled with fun and adventure.
