Scuba in Bermuda

I'm going to Bermuda on the Norwegian Escape this august. We have never been there. I was wondering if anyone knew what scuba company does NCL use? Should I book scuba through the ship or just book my own? I have read a lot about Fantasea diving, which got a lot of good reviews. If you don't use Fantasea, what company do you use?

Thank you in advance

We'll be on the Escape end of June. Fantasea is located in Dockyard, and their time is the same as the NCL diving excursion, so I'm thinking it might be the same one. At least that's what we are banking on as Fantasea looks good to us. I booked through NCL even though $20 more pp. We had the $50 shore ex credit we are using. Plus I figured if any delays with getting into port on time, we didn't have to worry as book through NCL vs direct (which requires prepayment and 24 hr cancellation).

We could not find another company that was easily accessible to Dockyard.
