Thank you for the explanation… there must be a few hundred other videos on YT telling you how to turn TN on and that it “changes the degrees a little bit” with about zero other information. Subscribed!
You should take a look at the spyglass app, it is very useful, and intriguing, and has some other useful features. Without telling my age, way back when we didnt have phones or gps units, I carried a compass and an assortment of maps. Topo 1:150000 scale, and a sectional aeronautical map, higher scale with a little less accurate map position due to the scale, but effective enough. I was a paramedic, and we had a call in the swamp. I could hear on the radio, our dispatch trying to get the helicopter to us, but i knew the bayou he was telling them was not where we were. So i pulled out my compass and aeronautical chart, and figured the co-ordinates that was about 300 feet off target, but the pilot was still awestruck to how close the co-ordinates were to the middle of nowhere. Yes the old tried and true is reliable.
Thanks for the great comment. I love to use Avenza Maps and my GPS watch, but there is no substitute for a map and compass. And more importantly, knowing how to use them in conjunction. Check out my Land Navigation series and Avenza Maps series. Thanks for watching!
Also, the magnetic North Pole is moving, so the adjustment changes slowly. It’s changed a few degrees in recent decades. So make sure to keep your declination up to date each year or so.
Good stuff. For part II might be useful to talk about how to set declination on magnetic compass as many get confused by adding or subtracting the degrees. I like to remember, West is Best = add and East is least = subtract. then also have to consider declination changes with time and need to account fo the age of the map. Happy Adventuring
Thanks for the suggestion. Declination is the part of my navigation class where people get the most confused. A video with some visual references will definitely help. There is a good way to remember using Army ranks. I'll add it to my To Do list!

My compass doesn’t even work. It shows the latitude & longitude, & elevation but the needle doesn’t move. I’ve tried rebooting and reset the location in security. But still nothing.
Finally professional and specific, thanks a lot and thumbs up! Great and Pro video. Can you tell me: In North America (I live in Canada) geodetic charts navigation is by TNorth o MNorth ?.
Each map and chart is different, however, in my experience most maps are aligned to true north. The only exceptions I have seen are with orienteering maps. The map should have the declination noted or a compass rose with true north on the outside and magnetic north on the inside. If you are interested in maps, check out my Land Nav series: ua-cam.com/play/PL0JzmvrJfyEQ7mLgesV8Ue6wU-iWwsIqJ.html Thanks for watching and the kind words.
Are all Top Maps lat/lon and UTM lines set for true north or magnetic north? Why don't they have an option to re-orient to magnetic north so folks could use a compass without declination adjustments.
Most commercial maps are oriented to true north. Orienteering maps are drawn to magnetic north. You can actually draw your own magnetic north lines using a protractor.
If True North is so important, then why doesn't the Iphone come set to orient toward True North? What is the value of having it some set for Magnetic North?
In order for iPhone true north function to work, location services also must be turned ON and the compass app allowed to access location in addition to turning ON the "use true north" feature ...correct?? I would assume without location services ON the phone cannot calculate the declination. Your thoughts....
Great question! The iphone compass uses a magnetometer sensor (i.e. a magnetic compass). The location services are only needed if you want the Compass App to also display your Latitude and Longitude. The compass app still works with Location Services off.
@@OutsideChronicles Thanks for responding....I realize that the iPhone compass will be able to read magnetic north anywhere without location services turned on, but as you point out, declination must be known to determine true north....correct? Thus, for the phone to display true north it must know where it is geographically.....I think the phone determines where it is using cell towers or GPS or both....and maybe it uses this info. without turning on location services for true north display....but if you are in a remote area with no cell service or GPS reception...and thus no location services....how can the phone calculate true north....that is gist of my question......your thoughts....
@@proengineering661 Ahh, I missed that. You are correct that it will need to know location to lookup the correct declination. My guess it will use the last known location to calculate if location services are off. I have not really tested that feature. I guess the moral of the story is to still use a map and compass. The map for your location should have the declination and I use a compass where I can set the declination rather than mentally calculating each time. I personally would not rely on the iPhone compass app for serious navigation.
Honestly, unless you are traveling long distances like > 10 miles, it does not matter that much. And if you are navigating for distances like that, you are using a compass with declination adjustment.
Sorry for your troubles. My suggestion is to take it into the Apple store. Does the compass work in other apps like Gaia GPS? Perhaps there is a hardware issue.
Fyi - it’s not obvious, but you CAN set your heading in the IOS compass. You just touch the top of the heading arrow and it’s sets your direction - until you clear it.
why is’t magnetic north not the real north ??? is real north map north so actually fake north? How often and how much does Magnetic (real) north change ?
North on a map is true north. The north on a map points to the north pole where all latitude lines converge. Magnetic north drifts at a rate of up to about 9 miles per year and has actually increased to 30 miles per year. earthsky.org/earth/magnetic-north-rapid-drift-blobs-flux
@@OutsideChronicles wow, thanks. I wonder why that change happens. I thought magnetic north was straight above but different than true north because the earth globe is slightly tilted.
@@NazaninExplore Scientists are not 100% sure why magnetic north moves, but most suspect it is because the core of the earth is fluid, i.e. molten metals, along with the earth rotation.
The problem with electric compasses is they need constant recalibration. To do so you must wave it with a dead cat over your head in a figure eight pattern. You won't know if it's correct or not. But, you won't deserve to. If you're going to use a smart phone, just use the darn GPS. The phone would need that and data to look up your declination anyway. If you already know your local declination, just allow for it. If you don't, why are you even using a compass?
True North is the same no matter where you are on the planet. Magnetic north differs depending on location (i.e. declination) and the magnetic field is not the same everywhere on the planet. Finally, magnetic north drifts over time.
My advice is not to rely on an iPhone compass when doing any serious navigating while out walking in the wilderness. I own three iPhones for different reasons and each gives a slightly different reading for both True North and also Magnetic North. Much safer to buy and use a good quality magnetic compass and adjust for magnetic declination in whatever area you are in.
Sorry bro, declination in my area is -10.4 degrees. Can make a big difference over a few miles. I would not use my phone to navigate. I rely on a map and my Suunto compass.

Thanks! See you outside!
Great video I subscribed you info has helped me understand a lot thanks for sharing 👍👍
Great point! Also might want to explain how you have to set up the iPhone to allow it to use your Current Location.
I only use it to navigate when I’m hunting. Very rudimentary. I would not use it for a Land Nav exercise. Good video. Thank you.
Agreed, there are much better apps for navigation and tools (compass). Thanks for watching
Great video thanks man

My pleasure, see you outside!

What did you take a bearing on in the bayou? Without prominent features in view, it's not possible
Also, the magnetic North Pole is moving, so the adjustment changes slowly. It’s changed a few degrees in recent decades. So make sure to keep your declination up to date each year or so.
Correct, you should always look at the date in the map. Also, the drift seems to be speeding up over the past 50 years. Thanks for the comment
When I set to “true north” my iPhone locks the compass… do you know why that happens?
Thanks. Now I have true north without an mental gymnastics.

Good question. Other than some orienteering maps, maps are created with true north being the top of the map.
Should I use truth north option always in google maps to get right directions?
That setting is not going to matter in your mapping programs. It adjusts automatically.

My compass on iphoneX freezes no matter how i tried re-installing many times....please advise me how to do
Sorry for your troubles. My suggestion is to take it into the Apple store. Does the compass work in other apps like Gaia GPS? Perhaps there is a hardware issue.
If its freezing when you set to use True North you have to enable Compass calibration in the Location/System settings. Its off by default i believe.
Fyi - it’s not obvious, but you CAN set your heading in the IOS compass. You just touch the top of the heading arrow and it’s sets your direction - until you clear it.

On my iPhone 13 I have no such choice… True North is nonexistent!
Also, if your battery dies or you brake your phone, you can be in big trouble.
