I live in Naples and will be in Key Largo that weekend and I love diving the Spiegel and Duane. Most operators will only do a 1 tank dive to the wrecks and then a shallow reef. But I know 1 operator who has a 6 pack and will do a 2 tank wreck dive with a 1 hour surface interval. All we need is 6 people so count me in if you are interested.
