Comments During my dive trip to the Big Island of Hawaii, I ended up using 4 different dive ops during my stay, each of which had unique features. In common, they all had the policy of no “island time” where Check-in was concerned, the goal was an on-time departure. The DMs at all the shops were mainly composed of veterans, middle aged full-timers to retirees that help part-time. Weather was in the mid-80s every day, and with water temps around 80F, I did not use a wet suit, but I was in the minority. I will review each dive op separately. Note diving in Hawaii is expensive.
Jack’s Diving Locker was the op that surprised me the most, as I usually shy away from big outfits with multiple boats, but somehow they managed to make the experience seem individualized. After my first dive trip, I kept signing up for more trips even though it was 30+ minute commute to the boat. Highlights were the double dip Manta dive, where the 1st dive is in daylight so you can get your bearings and see Mantas in the daytime, have dinner and then dive for the Manta show which was excellent. The Advanced Dive trips were only available after they had assessed your skills on a standard dive, these trips went further to sites that were less visited, had some very nice dives. One final dive that they only take 8 divers is the Black Water dive, where they go out to the deep ocean and tether you to the boat with a 40’ line. Get to see creatures from the deep come up to the surface to feed on plankton. A great sight to experience 80 minutes went by in a flash.
The boats depart from a marina north of town, a car is needed, but parking is free and of adequate capacity. Crew is very helpful and you have the option of setting up your gear or having the crew do it. I did not rent any gear, however I did not note any of those who used rental gear having issues with it. Boats vary in size from 20 divers to 8. On the large boats, they arranged your gear location carefully, with groups 1, 2 & 3, from most to least experienced. At the site Group 1 geared up and each had the space of 3 tanks on each side, so gearing up went quickly, then Group 2 took their place and were geared up before G1 was finished entering the water. G3 geared up towards the bow where there was enough space for the crew to assist these divers. The process went quicker than the typical madhouse on other boats where everyone gears up at the same time in close quarters. Coming back to the boat the process was reversed: 3, 2, & 1 got on the boat in order. One little change made a large boat seem small. I appreciated not having to bounce around on a tag line 10 minutes, while the DMs sorted out the chaos.
All the boats had a camera bucket, and sandwich box was provided during the surface interval which was one hour. Prices were comparable with other dive ops, note that it is expensive, a 2-tank trip starts at $160.
