Well, I for one, read your report and thought it was unfortunate that you had a bad experience. I did not email you privately, not sure why I would do that. My positive review of Jack's is on here in a couple of responses I have made.
We did have a good experience, including our three kids getting certified through Jack's. Since you were paraphrasing, is it possible that the kid was just happy that he no longer 'had' to set up his own gear? I know my kids joked around about our gear being set up for us, while they had to do theirs while they were doing their certification. If the kid was on the boat with a parent, perhaps he was joking and you just did not get the joke. Don't know, wasn't there.
The other thing that struck me, was your comment on the idea that you could shore dive one of the sites. Possibly, again- no expert here. But, some areas on the Big Island may look accessible and may be accessible only if you are of a certain heritage. Also, some sites may look shore doable, but you may not realize from the boat that there might be a long hike over sharp lava.
It seems a bit unusual for Jack's to send in a group without the guide. Our experience was that everyone went in and waited on the surface until the whole group was in the water, and yes, that sometimes took 5 or more minutes. Were you supposed to drop to the bottom and wait?
Jack's also uses integrated weights, not as hard to drop as a weight belt...but it is doable. I have seen posts here at SB about that.
It would be interesting to know what your friend, Bob, thought of your experiences.
Any links to your articles? Always interested in reading about other people's experiences!
