Hey guys,
There is a pre dive lecture to go over the rules, the gear, etc and we have a divemaster in the cage with you. All are full face masks and you can talk to each other, as well as family/ friends outside the tank.
Total time in the water is atleast 1/2hr.
I dive the tank to clean it, etc and I didn't think I would like the cage that much after free diving in the tank, but I found myself enjoying it very much. It is a totally different experience, our dive masters are very good and patient for those who have never been diving. They are usually busy on the weekends with it, so you can come in and check it out first.
The four dive groups for the day get the lecture program all together in the a.m., then we rotate through the group with the actual dives which are about 1/2hr each. We did an engagement from the tank, also had a couple get married in the cage with a pastor as well.
