Simple Questions from new diver

[ilightyouup]

Hey all,

I'm new to the forum and don't live in MN but you guys and gals really seem to have your SCUBA stuff together and i'm hoping you can answer a few beginner questions. First, i am recently certified open water and want to go on a night dive when i'm down in the Caymans next month. Do i need additional training to do this for the first time or can i just go, advise the DM of my situation and get a signature from my DM after completion of the dive toward my Adventure Diver Cert? PADI is not very clear about this on their website.

Second, I'm thinking of buying some used equipment, but only if i can be sure that my shop in CT is qualified/certafied to check it out and gaurantee that it is in sastifactory condition before diving. What certification should i be looking for?

Third, and final, how did i miss the joy of diving for so long? What a truly great sport! Thanks in advance,

John B
