I went with Jack's Diving Locker on two night manta dives. If you want to learn a little bit more about what you are swimming with, Keller Laros is the guy to go with. All of the DMs/guides know the manta quite well, but he is one of the co-founders of the Manta Pacific Research Foundation; Manta Pacific Research Foundation He was one of my guides through out my 5 days UW. Although all the dive ops on Kona are pretty good, JDL gets my vote; great (new) big boat, excellent service, good crew, that became my friends. I'm already planning my next dive vacation there...
Dove with Keller on JDL boat in May of 2006. It was great. His video was awesome. The boat was not too crowded that night, but as mentioned the bottom is very crowded with all the boats there.
