I dove three days (wish I had more time!!) with Honolulu Scuba Company in August 2013. They picked me up from my hotel, took all diving and liability information, took me to the very clean boat, made sure I was comfortable (I have my own equipment), gave a very thorough boat safety briefing, gave a very thorough and detailed dive briefing, and away we went. They also offer intro diving, dive cert class, and other dive instruction. What impressed me the most was the ratio of dive masters/instructors per person. Almost a private diving experience! All were extremely knowledgeable about the dive sites and were extremely conciencious and helpful to their divers, no matter what their level of experience. Special thanks to Vic, Kate, and Victoria. Mahalo!
