If you are drift diving, you will be paired with a buddy, and the two of you will be given a flag. Thats how its done in South Florida, and trust me, with the way people pilot their boats here, you want the biggest baddest flag you can find, and a seasoned local captain. Depending on the skill level of dive you are interested in, I will be happy to make some recommendations for charters out of Pompano.
Easy no stress diving - Scubatyme - Most of their dives are relatively shallow (under 100') and their captain knows the reefs really well. This is the most newbie/family/diver friendly boat in Pompano. If I do a charter its usually this one, as its so well run there is no stress no fuss or muss. Also, no serious challenges, or advanced dives.. Probably not a good choice for a more advanced diver, looking for a challenging dive -This is the boat to just chill out on and enjoy the reef. Not every dive has to be the Titanic!
Tech Diving/regular rec diving - Pompano Dive Center - A little more on the divers dive charter level. If you want to do deep tech diving, or want to dive wrecks like Rodeo 25, then this is a good choice.
And of course, there is Miss Conduct, Conrad is probably one of the best captains in the area - Smaller boat, caters to divers requests.
Again, tell me what sort of dives you are hoping for and I will help you as much as I can. I live very close to the charter docks and have been on most of them.
