My husband and I just returned from our trip to Kona where we completed the pool instruction and first two open water dives and earned our Scuba Diver certifications. My husband is not comfortable in the water and were it not for the patience and competence of our diving instructor, Erica Deen, I doubt he would have been able to... more

Prior to heading to Hawaii last week I had read about the manta ray night snorkel/dive trips but for some reason I was terrified to do it - those suckers can be 14 feet across! Once we arrived on the island I thought about it some more and we ended up calling the company that was recommended by our guidebook.... more

We just got back from a week in Hawaii and were lucky enough to dive with Jack's twice during our vacation. The first was the afternoon and Manta dive and I can't say enough great things about the experience. One thing I liked was that we were able to do the manta dive for about 35 minutes and then do... more

Our group went on 2 dive excursions with Jack's, first was a day dive, then the famous manta ray night dive. The day dive we did was disappointing. Although the people in the shop were fantastic and the other guides on the boat were friendly, our guide did not even speak to us. We actually thought our guide was someone... more

This was our first time diving (we are not certified yet). Myself, my husband and my 10 yo son decided to try it out. Sven, our instructor, was beyond helpful, informative, and fabulous. He went the extra mile to make sure we and our diving buddy (16 yo Evan) were comfortable and understanding everything he was teaching. I was a... more

Jack's Dive Shop is fabulous- very professional, knowledgeable, helpful and courteous. The night Manta Ray dive is special. It was an incredible once-in-a lifetime experience that is highly recommended. Though a bit chilly, in part due to the lack of movement and the absence of the warm Hawaiian sun, the interaction with the 20 foot manta rays, drawn to food... more

My husband and I were in Kona for a wedding in May 2008. We managed to get away from the strict itinerary and decided to try out Jack's after we read about it in the travel guide. Because time was limited we called ahead of time for some information. The person we got on the phone (his name escapes me)... more

We just returned from a two week vacation in Hawaii where we stayed on both Oahu and the Big Island. After reading many reviews regarding scuba and snorkeling companies, we chose Jack's Diving shop. I must say we were very disappointed. We felt like it was a group of guys who like to go diving together and get the tourist... more
