Having done several of both trips, I didn't find all that much difference between the trips, other than the addtional tank on the 3 tank trip. The only ERDA dive I've done with a different "feel" to it is the Wednesday "Adventure Dive" (That's their name -- I think of it more as the "Dive with Ed" trip). It's more freeform and they don't insist that you stay with the group.Has anyone done the three-tanker with Ed Robinson's? According to the web site, it is geared toward more advanced divers and lets divers dive their computers and tanks, rather than an arbitrary dive time. We'll be staying in Wailea for a week in August. Since we'll have just come off the Kona Aggressor, we only want to do a day or two of diviing in Maui.
Dives are generally limited by air on the multilevel dives such as Molokini, and by decompression limits on the square profile dives (such as St. Anthony's, 85' Pinnacle/Hawaiian Reef, 110' Battleship and Apartments). Even with 1 hour SI's, staying within (or nearly so) NDL limits ends up being the limit on dive time on most 2nd dives and definitely on 3rd dives on the 3 tank trips.
The 3 tank trips do tend to be a bit deeper and they will often go to 130' for a while at Molokini, and then work back up to the shallows. On the 2 tank trips it is common for the more experienced group to splash in before the other group, to go a bit deeper, and then to end the dive after the 2nd group.
==============
Here's the data from my last 3 tank and last couple of 2 tank trips with ERDA:
3 tanker, Sunday 3/9/2008. #1 Reef’s End Drift. 127' 0:44 runtime. IIRC, this was air limited, with the DM and me being the last up.
#2 Taupe Reef. SI of 1:19, then 82' 0:36. NDL limited. Lots of air left.
#3 Backwall from cove CCW past the lighthouse. SI 1:06, then 69' 1:00 runtime. I don't recall the reason for ending the dive. Probably not my air. Most likely because everyone else had surfaced.
2 tank Sunday 3/23/08 #1 Molokini sand channel, center reef, inside of reef’s end. 118’, 0:56
#2 Red Hill drift. 0:56SI, 51’ 1:07. Ascended because we had reached the end of the reef system.
2 tank, Sunday 3/30/08 #1 Reef’s End drift. 123’ 0:57. The rest of the group had swum off into the blue to do safety stop, and although I had enough air to hang out in shallows on the wall for quite a while, the DM was having a hard time splitting the distance to keep both me and the rest of the group in sight, so I came out out to join him.
#2 Landing Craft. 1:13 SI, 64’ 0:46. NDL limited.
--------------------
Several other Maui dive ops pretty much let you dive your tank and computer, but most DMs start getting restless 5 or 10 minutes after all the other divers except me have gone up. The most notable exception is Pauline of Mike Severns. Several times I've started to ascend after an hour or so and she'll be excitedly calling me back down to show me something like a chocolate dip damsel fish showing the mating colors of white eye/white eye ring. She just never wants to go back up.
