Cavern Diver Course

Most divers that contact me want to learn how to dive in caves. They are willing to commit the time, money and effort to become certified as cave divers. It is a HUGE commitment. Sometimes we get divers who are not so sure they want to commit to all of this but yet want to get a "taste" of overhead diving. If you fit into that category, the Cavern Diver course is for you. Great Family Fun!!
For these divers we offer the single tank cavern course. You can take this course with your normal recreational scuba gear, with very little change in the open water configuration, plus a couple of underwater lights. This course trains you to dive within sight of the daylight zone, or cavern entrance and is not a prerequisite, nor does it count toward cave diver certification. The course may not be taken using double tanks, whether they be side or backmounted. This is a single tank diver course only.
This course will definitely make you a better diver because we focus on things such as running reels, buoyancy control and trim as well as basic dive planning and gas management. You will also be able to dive at certain dive sites that open water divers are not allowed to dive such as Orange Grove Sink, Madison Blue Springs, Devils' Eye, Devils' Ear.
