No mention of setting the bezel and aligning it with the North, or how to use the ticks on the dial to see adjust your heading or see if you are deviating from your course.
I seem to recall something about rotating the bezel, and then keeping North/South in line, so you just have to make sure they line up, rather than remembering the actual number?
At last an explanation that most newbies will understand, simple and straight to the point, of course there's more to it but great for people who know nothing about underwater navigation 👍
Wish you would’ve covered changing direction underwater. For instance if you have to swim to a certain mark underwater, and then turn and swim to another point.
I am a complete newbie to compass navigation. Did I miss something? Did this man mention anything about the North Needle to then set your bearing? I am Googling many sites to try and understand how to use a compass under water. BOY this man talks fast. Very informative, but missing the crucial explanation of the North needle to set up your bearing (unless I missed it in his very quick chat?) and could talk slightly slower for me to grasp what he is explaining.
Yeah what he forgot to mention is the part where you turn the bezel on the needle. So you can see if you swimming in a straight line. On 01:57 you can see the 0 on the bezel below. Above that you see those two pyramids yes. Keep the needle between those two when going on your way.
Great job! Love advice to incorporate observational way points and to look "over" the compass using the window or the lubber line. Excellent! Couple additional points: 1. It is critical to recognize that these compasses are not that accurate no matter what you do, and are going to be off by 10% or more the further away the objective so set the target goal a little to the left so you know you need to search right when you get to the location (best done using a weight and spool to circle accurately to the right); 2. You must, must, must estimate distance so you have some reasonable idea where to make the adjustment to begin turning right to search for your objective. Otherwise you have no idea where you are! Best option is to use kick cycles but you can use breaths or time but I find these too subject to being influenced by effort on a long swim. Bottom line: You need both direction via the compass AND distance to hit your mark. Finally when you use the "arm crook" position or figure 4 position place your middle finger in the elbow notch to ensure the crooked arm is at a 90 degree angle. I like bungee mount on the back of my right hand, but that is just a personal preference. Good Luck!
Other than going to the surface to sight the boat, is there a way to pinpoint a boat's anchored location when you leave it, and then navigate back to it using a compass? Other than swimming a straight line out and back again (or swimming a square and counting kick pairs)? It seems easy to swim around looking at things and then realize you have no clue where the boat is.
If your azimuth (swimming direction) is more than 180, subtract 180 and that is your return azimuth. If your azimuth is less than 180, ADD 180 degrees for your return. Example..... You're swimming due west at 270 degrees. To return, you subtract 180 degrees and swim back due east at 90 degrees. If you're swimming due east at 90 degrees, ADD 180 degrees for your return and swim back due west at 270 degrees.

You should try navigation computer www.ariadna.tech
How is the bezel used?
Perfect thanks. Great video
Lol what?! You didn't even show how to operate the needle?

Thank you buddy for the brief breakdown
And please describe or ADD another video on how to set a bearing to the destination and returning from the destination.
Do you have an updated video that shows when you're making turns underwater and what to do with your compass?
A really great video, thanks for posting.
Ecxellent explanation!! Thanks

Great video!. Very good refresher.
This a very concise video with nice reminder info for my OW students. Thanks so much! :)
what is the make/model of the compass you are using?
How to navigate back?
If your azimuth (swimming direction) is more than 180, subtract 180 and that is your return azimuth. If your azimuth is less than 180, ADD 180 degrees for your return. Example..... You're swimming due west at 270 degrees. To return, you subtract 180 degrees and swim back due east at 90 degrees. If you're swimming due east at 90 degrees, ADD 180 degrees for your return and swim back due west at 270 degrees.
Great overview.
Hey thanks for the information. Great review. Been out of the water for a while and itching to get back in this spring.
Very well explained . Thank you from a learner diver
What is the rotating ring on a compass used for?
Yep, covering how to take a heading is great and all until you have to turn and don't know what / how to get a reciprocal
Looks like South Florida
Worst explanation ever, didn’t mention the rotating bezel, the relation of the index marks to the north needle.
