Hea,
doing a (small boat) dive on sat. then probably shore dive on sun. eather hunama, or blow hole...
South shore is looking good ... we're planning a trip to hanauma bay on Monday. May go to another south shore site haven't decided yet.
Dove Hanauma bay once before, we did 2 tanks (if you're going to bother taking all that gear down might as well do 2!). Military gets in free with your I.D. card and only $1 to park. They charge to use the shuttle though which is needed with all that dive gear, weights tanks, etc... they also charge extra for you to put your gear on the shuttle. Think it's less than $10 both ways, with gear.
Have you dove the blow hole before? I've been there to take pictures before when it was rough and definately looks dangerous sometimes.
I'm also military I'm in the Dive Oahu dive club but when my membership there expires I'm probably going to go with Sea Lancers .. I have my own tanks and I've heard for $5/month they'll let you fill your own tanks after training on how to operate the equipment.
I'm here another three years ... been here three already.
Edit: Looks like it's $15/month .. oh well cheaper to stick with Dive Oahu, I'm in the club mainly for the free air fills, though they do free shore dives (if u have gear, it's $1 to rent 2x AL 80's for the club shore dive) too usually every other week but seem to keep canx them because of surf on North & West shores, wish they'd do something on the South shore. Dive Oahu is the shop in the NEX, they also have a shop in Kewalo, Kaneohe Bay Marine Corps base and on Camp Smith.
