Well, where ever you go. Expect wrecks, reef and wall. Coves is south west, Bahama Divers is North East.
Coves has lotz of wrecks and wall. Bahama Diver's has the Blue Hole, wrecks and reef. (GENERALLY the wall is too deep in the NE for BD's and the Blue Hole too far for SC's. )
With BD's The blue hole is cool. But considered advanced if you go in. look for the large nurse shark who's often in the cave if you get down to 85'. Any of the reef is nice but on surgey dayz very shallow! Trinity cave's is a personal fav. also The de la sal and the Mahoney. If the dredging's stopped the Light house reef, right at the mouth of the harbor always had LOADS of life. (i've not dived in in a year or so coz of the dredging)
With Sc's (more normally lea side of the island) the wall is always impressive. Many of the wrecks are just on top, so on one dive you get some deep wall action and a wreck crescendo! There's reef too. If you're lucky (or moan like a ****) you'll hopefully get to Port Nelson (with Bacardi Reef), Razor Back Reef, Steel forest or twin sisters. More sedate dives (and only marginally less impressive) include The bond wrecks (vulcan bomber and Tears of Allah, the vulcan bomber is actually a terrific night dive but the site is shallow (40') and silts easily), David Tucker's always a goodie, The Will Laurie, Tunnel Wall, Abilin wreck, Lampton wall and sand chute.
The Ray of Hope used to be a personal fav. The Stuart Cove reef shark feed (which would surely feature on a list of must do's) is often near by so there's normally a few kicking about the wreck. Sadly, some pillock in a freighter dropped a large anchor right in the open hull, then drove round in circles trying to free it and mullered the wreck. It now has cables and loose fixtures dangling from fore and after castles (if that's what their called) splintered timbers and other dangers all over it. The hull itself doesn't even look too structurally secure anymore. The hulls broken backed across the middle leaving four quarters of hull wall enclosing the hold, i got $10 says at least two of'em dont last this season's first weather system......
Let us know what you choose and how it goes?
Good luck!
