I agree with everything splash said, also, the buoy is gone now so its a little harder to hit them perfect but still very easy for the most part.
My sonar always puts it at 70 feet of water.
In addition to the two big boats, there is a large barge (100' ish) like 300 ft NW off the stern of the BT. It gets hit alot less and is stacked full of fish including mangos, hogs, jew fish and sharks. Cool thing about the barge is its proximity to the ledge that runs just off her allowing for a wreck and ledge dive on one drop.
I was there a few weeks ago and saw a freaking hammerhead, super cool.
