Service Club Today and Navigation

Great day to do an underwater navigation dive at Service Club - 5-6 feet of viz and 74 degrees in the water! Students did great. They are all working on getting their Advanced Open Water.

Underwater navigation is something that you start to learn, but only through a lot of practice can you become really good at it. Good question came up during class - "What makes a good underwater navigator?" In my opinion, there are a few things:
  • Always knows roughly where they are at (even if they aren't leading the dive)
  • Uses both natural navigation, estimation and compass to find his/her position in the water
  • Knows the bottom topography
  • Has a mental picture of the dive site in their head at all times
  • Can estimate how far they will move in 5 minutes of dive time
  • Knows which way the ordinal directions are (N, E, S & W)
  • If they feel lost, they stop, take time, move in a safe direction if needed to locate themselves
  • They are comfortable with their compass

So, finding yourself isn't that hard, it is really about practice and starting out with a solid foundation of the basics. let me know if you have any questions, or comments. I'm sure a few of you will have something to add to my list above! Greg
