Dive’s 15 & 16
These 2 dives will be tailored to the group’s capabilities, and will be an opportunity to explore techniques designed to safely extend cave time. The objective will be to spend as much time in the cave as the group is comfortable with. By this point we should be thinking and diving like cave divers, this is your chance to really enjoy the caves and show off what you’ve learned. As always, be prepared to be tested!!
Notes: This outline can be changed for any number of reasons relating to logistics or performance of the group. I hope it will help you visualize what you can expect from the course. All candidates should have had the chance to thoroughly read the NACD Cavern/Cave Diver Workbook as a minimum before starting the course.
