I just did tunnels on the third and it's a great topographical dive, lots of arches and swim throughs, I did it with fathom five, and on the second dive we did the outer reef, vis was decent probably 60 ft. Also did dives with fathom five right out of poipu, and easily had 100 ft vis, at a spot called fast lanes, and second dive at sheraton caverns, lots of big fish, tons of turtles at both sites! Greg with fathom five was a fantastic DM! I also did a two tank out of port Allen with bubbles below, the captain Earl, I dove with last year, and again he was our captain this year, his knowledge of the area is top notch, and they are a good group to dive with too!
