This is one of many NZ dive operators that we have dived with and have found it to the one of the best for a number of reasons.
First, they were so great to pick us up from our accommodation. The boat was smaller but was very well kept, had a toilet, and provided enough room for all of us. The crew was Lance and Simone. I found both of them to be the type of people you would hope find in the business. They love what they are doing and really care about marine conservation. The safety brief was very thorough. We were well informed on each dive site and Simone did a good job of keeping track of each team while in the water. The diving visibility was about 15 meters so not ideal for this location but definitely could be worse. In between dives we were well catered to with hot drinks, biscuit, and a sandwich. We actually had some young fur seals swimming with us plus we also saw black coral, butterfly perch, scorpion fish, moki, crayfish, snake star, and few more creatures. If you want to really experience Milford Sound then I suggest doing it with Descend Scubadiving. If I had the time I would also do a drift dive with them.
