Jim and I recently got our certification. My first dive was rough, faulty equipment and ear trauma, but we both did very well with our next 3 dives in spite of 6 ft visibility. Our instructor, Marti, was fantastic. Now, here's a question to the more experienced. We have an opportunity to dive in Cozumel and I understand it is a drift dive. Any opinions out there on whether we are biting off more than we can chew? There will be a dive master in the water with us.
