Hey Rob, I work for Island Divers Hawaii (
Hawaii Scuba Diving with Island Divers Hawaii - Honolulu, Oahu, Hawaii, Waikiki) which is located on Hickam AFB right next door to Pearl. We 've got a few Inspo divers on staff here and we just signed on as dealers with Silent Diving and are waiting for our order of 2L tanks to come in. We have a full gas blending station so air/O2 is no worries and we're one of the few shops that allow Rebreather on our dive boat, and the only RB shop on the island.
Our dive boat goes out every day. Military rate for boat charters are $65 (If you're not active duty it's $85/charter) but you're going to be limited to OC profiles/times. We do offer longer CCR dives but they cost more because you have to rent a staff member for the charter. I believe the CCR/Tech rate is $130. But we do run some specials several times a month that we can talk about, they would only run you the $65 ($85). We do require CCR divers dive with a bailout tank of 30cf or larger.
As for conditions, you're lucky, the water is warming up we're now up to around 76/77 deg F and by mid summer we should be 79/80, so most people are wearing just 3mm full suits. For longer shallower dives (<100') I usually add a 3mm hooded vest. For the longer deep dives I pull on the trusty 5mm.
Vis of course is almost always great. Let me know if you have any other questions.
