I have been diving with them for the last few years, I have had alot of experience with operators in cozumel and they are the best i've met. They try harder than most and their crews are usually (note this is mexico) on their toes because of them. They are tactful with new customers and judge their abilities accordingly, if your experience is evident you will get your bottom time, and dives not available to all, depending on the others on the boat, Rita will stay with you and unless your using dual tanks she will stay down with you until your exhausted. They are definately not a cattle boat. I have never had the experience of a cattle boat and really don't ever wish to. Also they are the type of people that are friends to you forever, usually the groups I've been with have all gotten together at least a few times to sample food (and drink) at out of the way places, and gotten that much closer in the process.
They are wonderful people and I am glad to call them my friends. You will not be disappointed with their service, and amenities.

P.S. a neat thing i've learned is to tip the crew BEFORE diving, not as a group afterwards, you'll note the difference, you can of course split it with the same results
