The Legendary Devil’s Throat

Devil’s Throat is a right of passage for many divers.  Not everyone gets to dive it and for a good reason. It is a very advanced dive in Cozumel, and we don’t take divers there unless we know they can do it safely.

Devil’s Throat is a right of passage for many divers.  Not everyone gets to dive it and for a good reason. It is a very advanced dive in Cozumel, and we don’t take divers there unless we know they can do it safely.  Presenting an advanced certification is not enough. We are a safe dive operation in Cozumel and need to see you dive before and be confident that you are a solid diver both in air consumption and skills.  Devil's throat is not for the faint of heart, and we don’t take anyone that is not completely confident down there.

Those that qualify will be rewarded with one of the best dives in Cozumel!  If you didn’t see a single fish, you would still be blown away by the incredible coral formations and spectacular vistas over the wall. The site is the Northernmost part of Punta Sur.  It is a massive coral head that is like swiss cheese! At 83 ft you will enter the swim through we call the foyer. It is a large room with glassy sweepers and a sandy bottom. From there you will go up into the darkness to start the legendary swim through.  It gets darker and darker to the point you can barely see the divemaster or diver in front of you. Just at the point that you start to freak out, you see a beautiful blue light ahead. The throat itself is a vertical drop down to a sandy bottom tunnel that runs the rest of the way to the wall.  You will pop out into the light off the edge of an endless drop off at 135ft. If you do not get too narced, it’s exhilarating. If you are narced, it’s time to check your air and start ascending. From there we usually do a series of other swim-throughs in and around the throat til we start pushing our NDL or low on air.  Then we head up for our safety stop. Bottom times are usually a little shorter on this dive because people get so excited they forget to relax and breathe easy.

Next time you are diving with us ask a ScubaTony divemaster about the throat and see if they think you are up for it.  If they don't believe that you're ready, then ask them what you can do to improve your skills. This is a dive you don’t want to miss but all of the stars must align for us to go there.  The other divers on the boat need to want to do it, and they also need to have been assessed on a previous dive. The conditions need to be just right as well.  The best way to get there is usually private chartering a boat. The most common factor that we don’t go is that someone on the boat hasn’t been assessed or they aren’t up for the dive.
