Just got back from High Springs, Florida. My group of four went down to Ginnie Springs after signing up for the two day Cavern Course. They were two long days (12 hours each day not including driving time). We had about 8 hours of classroom training and homework the first night. We also did a "homework" dive the first night. We did 3 dives the next day after on land line drills and no vis drills.
The course was outstanding and the caverns at Devil's Eye and Devil's Ear were absolutely incredible!! We are so excited about practicing our newly acquired skills this summer so that we can sign up for the Intro to Cave course early next year.
Ginnie Springs was a beautiful place to dive and to just hang out. Even if you don't want to get cavern certified, you can still dive in the main Ginnie cavern and throughout the non cavern and cave areas.
One sidenote is that they won't let you take lights into the water around Devil's Eye and Ear and Spring if you are not cavern or cave certified. This keeps out (or is at least intended to keep out) untrained divers and helps saves lives.
Scheck Exley's accident anaylisis says that most divers die in caves and caverns due to:
Lack of training
Failure to lay a continuous guideline
Run out of air
Well, just wanted to share my new experience with you all in case anyone was wondering about it!
