Thanks for your opinion, Debbie, although I have to disagree. You were 5 divers for your first tank and one Divemaster. As for the second, there were 9 certified divers, 2 Divemasters plus one Instructor with her only DSD participant. On this 2nd dive you were taken to a site 40 feet deep which is just a sand patch away from a deeper one (45 to 75 feet) laying along a slope. You were not taken there for the only convenience of most of the divers in the group. Because of the incoming full moon, it has a current that divemasters assessed unfit for most of their divers' experience. As you probably remember, you were having problems while descending on your first dive. It happened again in the 2nd and the Divemaster came to assist you as you were separating from the group. Inflating the BCD at the surface is just a safety procedure. The instructor and the DSD participant you mentioned were still on the boat (certified and non-certified divers are not mixed), and they witnessed you yelling at the Divemaster. As you were so, say, adamant about not requiring any help, the Divemaster had to wait for you 2 meters below. I'm so sorry you did not enjoy our service or our reef. Most divers do, indeed. I fear the key is that you wrote to us earlier that morning asking for a cancellation on the grounds that the day was dark and cloudy. Since the sea conditions were fine (no waves, good visibility), it could not be granted as it is a shine or rain tour. And perhaps you felt forced to dive. I'm sorry, but that is the downside of booking in advance. Please, if you can tell your husband to send us the DIN adaptor we lent him and forgot to return, that would be highly appreciated. Kind regards!
