Ive been on about 15 dives with sea sport their really good . they have a new boat.
if you can take the trip Certified Diver Summer Niihau Three-Tank Dive (seasonal, May-September): For the Experienced Certified Diver, this is one of the best dives in Hawaii and is an all day event. Very few leave Niihau disappointed. The incredible wall dives, soaring lava pillars, and enormous caves, combined with bountiful fish, numerous pelagics, and unlimited visibility, dazzle even the most discriminating divers. The day incorporates three dives, two deep and one shallow and includes sites like Vertical Awareness or Keyhole, a 280-foot wall, Super Highway, Drive Through Cave and Lehua Rock.
well worth it Vertical Awareness rocks
