Simple Questions from new diver

Weldome to diving!! welcome to mnscuba

I wouldnt worry too much about the night dive. Make sure you let the DM know...You will most likely not do a dive deeper than 40ft for a night dive. In most cases in the tropics, you dont really need a light to see. the moon usually takes care of that. Do take one though as they are used for helping signal and for others to easily see you..including the capt on the boat. They are used to having newer divers in the water. The easiest way to know if yhour Equipment if serviceable by your LDC is to ask them what they service. I would imagine that you plan to dive at home as well, so i would be looking for something in the area of cold water regs...Used is ok, but you should buy it on contingency..of inspection..this will make it hard to purchase on Ebay, but you can usually find a shop on ebay that will guarantee their product..
G/L and welcome to the wonderful world of diving
