I haven’t stayed on Bimini but I have checked in and out of Bahamas customs there a lot on either sailing or liveaboards and while we are there dive and there is a lot of good diving in the area.
Just remember that the Bahamas sit on top of a plateau and Bimini is right at the edge of it. Much of it is shallow so when the tide changes all of that water starts moving on or off and currents can be an issue.
