One of the toughest things for me is keeping track of my position on open water dives. No matter how much I pay attention to underwater landmarks and my compass bearings, I often end up surfacing 100+ yards from the boat.
I’m curious what tips other divers can offer to remedy this problem, other than dropping breadcrumbs, carving directional arrows in the reef, or just leaving the navigation to my dive buddies.

well, just 1 1/2 weeks ago i dove on an old ore carrier that sank in 1910. it was only in 21ft of water and the weather was beautiful. we hooked into the wreck and worked up current. i just planned to surface when i was done, and my dive buddy wasnt very happy with that.
the vis was maybe 10ft at best, so maybe i could have run a reel.......

There are at least two methods of holding and using the compass. For navigation using a wrist compass, the diver wearing the compass on the left wrist would bend the left arm at a 90 degree angle, connecting the left hand to (approximately) the bend in the elbow of the right arm while holding the right arm pointing straight ahead. (Reverse if using the compass on the other hand.) If the diver is holding the compass with two hands instead of wearing on the wrist, the diver would hold both arms out straight in front of the diver, viewing the compass in the same manner. In either case, the compass should be squarely in front of the face so that the diver is looking straight ahead, seeing the compass while also being able see ahead out (over the compass) into the direction headed.
Common mistakes: With the wrist compass, failure to have the right arm pointed straight out ahead or to have the left arm at a 90 degree angle, causing the compass to not be pointed out straight ahead of the diver. (It is less common for the diver holding the compass ahead with two hands to fail to have the compass pointed out ahead.) The second mistake would for the card in the compass to be touching something, holding it from spinning freely. So, it is important to try to keep the compass level when navigating.

One thing that I do is take readings often and use landmarks as I go to ensure I have not left my course. I know when I don't do that I end up off course.

Hmmm, I think I know this sign. We will have to compare.... because I have one as well....

Don't wear two compasses side by side...

Do what I do. Have a kid who is a good navigator and get him certified.
