A lot of questions/complaints/stories come down to the all-to-true premise that the diver is ultimately responsible for their own safety. Especially for us newer divers, who may not have dived a particular location before, and who may not be aware that certain hazards exists, I thought it might be good to list some good questions a diver should ask a DM or dive company before booking a dive (maybe this is a bit biased towards vacation/resort dives, but it seems likely that these are the types of dives that a lot of newer/less-experienced divers will be taking part in).
Here are a few that I can think of off the top of my head; what else should be asked?
What is the water temp?
What is the max/average depth of each dive?
Will a DM/instructor be diving with the group?
Are there any currents in the area? How do you handle them?
What other hazards exist at the dive sites (boat traffic, maneating nudibranchs, etc.)?
Is this a drift dive? Is there an anchor/drift line?
What procedures does the boat follow if a diver is carried away by the currrent?
(If a large boat) Do you perform a roll call/head count?
How do you handle/pair off single divers? Inexperienced divers?
What emergency/safety equipment do you recommend? Are there any that are prohibited at the site?
What are the circumstances by which the dive will be cancelled?
