Each of the levels in the NSS-CDS curriculum (Cavern, Basic Cave, Apprentice, Cave Diver) requires two days minimum. If you lack the previous level of training, you will need to meet the requirements for the previous level -- someone with zero training wishing to complete Basic Cave would need a minimum of four days. There are also a few caveats:
1. In some cases, Cavern and Basic can be combined in one three day sitting, but that tends to be too much for some people.
2. Some cavern certifications may not not be accepted as equivalent. Generally speaking, this usually tends to be PADI cavern certs that are not accepted. The reason is because the process to become a PADI cavern instructor is no more than self-certifying yourself as meeting the minimum qualifications, where as other agencies require cavern instructors to undergo an evaluation.
On the gold line at Devil's Eye and other line changes front.. Ken Charlesworth, Lauren Fanning, and I extended the gold line at Devil's Eye 3 weeks ago, per the recommendations of the North Florida Line Group and last week Lamar Hires replaced the first 300' of gold line in Devil's Eye, basically from the new extension to the park bench, with gold line donated from the NSS-CDS Gold Line Fund. Additionally, last week a team of myself and Ted McCoy re-lined Potters Delight in Madison, which wasn't part of the recommendation from the North Florida Line Group, but was needed after the line was broken during "the incident" a few weeks ago. Today, a team of Ted McCoy and Derek Ferguson will be measuring the Peanut Tunnel and installing new distance markers, plus making the changes the North Florida Line Group report recommended for the Peanut / Challenge / Olson lines in Peacock. Next week a team plans to tackle the Olson / Cisteen part of Peacock, as recommended in the report. We will get to the final recommendation, T'ing the Godzilla circuit, eventually but it's not on the schedule yet.
