Scuba Dive Operator recommendation for Advanced divers
 

We're looking for a scuba dive operator in T&C that can cater for experienced divers. Sometimes we find ourselves in groups of newly qualified divers or inexperienced divers so get to only experience shallow & easy dives.
Also if there is a recommendation for an excursion company too, as it would be great to see the islands from the sea and perhaps visit some of the other islands. Thanks in advance!
