you must write a book so us old guys dont forget😊.

I love your content! Outstanding stuff... and presented in an accessible way. Just an offering to the algorithm gods... like, comment, subscribe and hit the all notifications bell, y'all!!! When I first saw your chart onscreen I was "that's some interesting terrain to have a 390/490 contour line!" and then I learned it was an error and you reported it to the Ordnance Survey.... BZ! Anyway... keep them coming.... sending out positive vibes from Canada.

The best orienteering channel on the internet. Period.

I’ve been following your channel for some time, I must say, I enjoy when you add history in your tutorials!! It an awesome journey, on what happened in the UK. Thank you so much for sharing your tutorials, your an awesome instructor and inspiring, it helps me stay in the woods with confidence!!👍🏽👍🏽👍🏽🇺🇸🇺🇸🇺🇸👊🏿 from Washington state.

Continual assessment is a key component to apply.

Hello! Congratulations on this content. Your channel is amazing! Could you please make a video recommending books on land navigation? It would also be interesting to see your opinion on these books. Even making a division between books for basic, intermediate and advanced levels.

Oldest point I've been to been set in Mason Neck Wildlife Refuge....

👍

For goodness sake don't walk up Icknield Street (Roman) instead of along Icknield Way (Pre-Roman)... you'll end up in Yorkshire !

When you set your compasses on the ground the needle stabilizes rapidly. Mine swings back and forth almost 160 degrees for over 10 seconds. Are there a lot of magnetic rocks in my area?

Great video! Next I’ll watch Time Team go into badger mode and dig holes in the wall😊

I have played out a scenario in my mind. It being, I have hiked 3 miles into the wilderness from my car/trailhead and camped overnight. Next day I have to go home but it's snowing and it's a whiteout. I know the general direction I need to go. I notice on the map a contour line takes me very close to my destination. Could one follow that line to get back to the trailhead using the altimeter? ( This is hypothetical; I have a GPS with SOS and map and compass and altimeter of course in reality, but I can't see more than a foot in front of me). What would you do in severe fog (we call it tule fog on the West Coast of the USA)

I’m famous 😮 Thank you for answering my question. 👍

Maybe one needs to use a toothpick as one does testing the doneness of a cake.😂 At any rate, I think you'd have to turn the cowpie over, carefully, preserving direction and see if one side is more dry.

Just curious, but I have Topo Maps with the declination diagram stating that the declination Increases Annually 3.3 degrees. The current declination is 10.3 degrees west. Does INCREASING mean it gets further west each year or moves closer to the true north alignment. Some maps also refer to a decreasing declination rather than simply stating a west direction or east direction. Thanks for any clarification of the above. Cheers!

great video Thanks , sometimes there are two line on bezel (one with magnifying lens). which one should be used ?

👍👍

Interesting tip i never remarked it but nice to now. The fix Magn. Decl. scale on the North side of the compass, the adjustable scale a-on the South side. Maybe i have never remarked or seen this because al my compasses always had a adjustable scale.

Interesting. I've found that a barometric altimeter is only reliable if the weather is settled. If a low pressure system is close by then the pressure will fall or rise significantly over a few hours. I've had my Suunto Core watch read 30m different at the end of of a run / walk than it did at the start, despite me being back at the same place! Yes you can recalibrate it at known heights during your walk but it's a bit of a faff. A good experiment is to set it for the known elevation of your home and leave it in situ on your desk etc for several hours and see if it thinks you have gone up or down in elevation. Also some GPS watches are more accurate than others. My Coros Apex Pro watch seems to be more reliable than my Garmin Fenix.

Thank you for the explanation.

arrhhhh, now i understand you, it was just semantics from my part. I always oriented my map back in the day when I knew how to use it properly, having a map not oriented just didn't make sense to me.

so a prismatic is better in my opinion

Your waffling adds a lot of "character" to your videos. I love it.

"Goodness is that the time?" "No, it's a barometer." "In that case it's high pressure I was off" Two Ronnies c1970's

If using the OS Locate app (and potentially others) on your mobile phone, be aware that the GPS reference ellipsoid zero height does not match the UK sea level at Newlyn with a height difference of 55m, so somewhere in the processing that 55m GPS to sea level difference has to be compensated for. Certainly on my mobile phone it's either done twice, or never, and when I look at the GPS indicated heights they are 55m 'wrong'. Different systems make different 'mistakes'. Always check your own readings.

I’m lucky to have both these watches and love both of them! I’ve had my Suunto Core for 14 years and never get tired of looking at its face. I’ve only had my Fenix 7X for a month but it’s incredible. I’m only just learning how to use it but so far its capabilities blow my mind. Thanks for all the effort you put into your videos. I’m ex infantry and precise map reading is a necessity in all conditions and you’re a great instructor. I also paraglide and use a dedicated leg strapped altimeter/vario (Flymaster) which is much faster/responsive at reading and displaying height changes.

Saluti dall'Italia, e grazie mille per tutti questi video magnifici!!!!

Welcome back buddy, I missed your company. 2 very important questions: 1: what kind of tea are you drinking? 2: do you brew the tea first and then put it in the thermos or (3) just put hot water in the thermos? Waffling on here with another, do you have a brown Betty? I just picked one up here in the PNW at a thrift shop for $12. I'm really getting into this tea thing as a former espresso guy. I'm drinking PG Tips and just recently got turned onto a Chinese black tea. Gimme a PO box or something and I'll send you some to try in return for all of the education you,ve contributed to my existence! Later, dude. Okay then, one more... Milk? Sugar?

Hi, love your videos. Can I just correct a small mistake? At 4.30 you make the very common mistake of saying satellite navigation can triangulate your position. In fact it's known as trilateration as positioning is done by the difference in time of the arrival of the different satellite signals. As you will know triangulation is the fixing of your position by taking angles. Even a major satnav (GPS) manufacturer once printed this mistake in their brochures so you're not alone. Two satellites give a position, three will give altitude as well.

It's great for the Scottish Munros when the chance of a cloud free summit is low, it's a long ridge with lots of false tops, and the kids (and other 'followers') keep asking "Are we nearly there yet" after each and every steep rise! Also great for knowing when to expect to reach cols, or traverse past problem terrain.

Can you make a video on strategies for Micro navigation in bad weather when there are very few collecting/catching features, handrails, visible references

Many weather apps will give you the current barometric pressure for an area. So, you can enter that into your barometric altimeter before you start your walk. Also, you don't need to spend £££ on a dedicated altimeter as there are many phone apps that will give your GPS altitude and many smart phones can measure barometric pressure.

Id never even thought about using my watch that way, I guess I rely on other forms of measure and havent kept up with the times. Its another useful tool for my toolkit, thanks for making this video and sharing your always impressive knowledge!

To say it’s expensive is an understatement. $134 currently!

I like that the barometric altimeter does not depend on GPS. Reception has become spotty in some parts of the world, suffice it to say. GPS won't always be there but air pressure will.

I usually do not walk across country, but sometimes for me, an altimeter is very useful. I use a 12 year old casio Protrek wristwatch. One of its features is a barometric sensor and a display either in hPa or height, which eventually calculates from the air pressure, as all barometric altimeters do. At sea level, this air pressure decreases at about 1 hPa per 8 m height gain. But there is a circadian rhythm, which today changed within 16 hPa (sic!). And there is variable moisture in the air, which makes it - and thus the pressure - lighter, Hence, barometric altitudes are random numbers, if one does not have reference points again and again, especially if the walk extends over hours. I find it tedious to always recalibrate my altimeter. I just memorize, how much I am wrong at a known point, and subtract or add the difference.

Hello, I have been watching many of your videos lately and as I enjoy the skill of navigation, I have been eager to watch the next video. I also have been enjoying your Waffle into history or other tangents of topics. Cheers!

2:10 Altimeter, not GPS ;-)

Sounds like I hav to tell my altimeter my altitude more than I need it to tell me.

Barometric Altimeters are also handy for weather changes approaching, set to 0 and in the morning see if it went above or below the 0 mark. Below is an indicator of low pressure and possibly RAIN. Conversely above represents a high pressure system and plenty of clear skies. Interesting tools indeed ! Cheers!

Got an ABC watch and I should use these features more offen, GPS has made me very lazy. Thanks for sharing your knowledge ❤.

Thx a lot Sir, I learned something new today....as I usually do when I watch your videos :) Wish I could join your nav courses. Greetings from Copenhagen.

Interesting and more uncommon topic. Thank you for makng this video I 'look after' a handful of OS benchmarks in my home area. A neat infill of yellow paint keeps them visible and hopefully less likely to get interfered with. There is some nostalgia in my motivation but mainly they are to provide a handy local reference for calibrating portable barometers /(altimeter) to QNH. The paint makes a difference , our yellow crowsfeet have apparently featured on a local interest Facebook site. (An Irish boatman).

Enjoyed the video very much. One way I've used altimeters is to follow a contour line, say, 530 meters until I achieve a specific compass heading then use that as an attack point. Again, great video and instruction! Cheers

Would being under a fleece sleeve or waterproof coat affect the accuracy of the barometric altimeter - ?

If I ever get over to Great Britain, I’ll be sure to drop in.

What do you think of the thommmen altimeter bit old school i know but not reliant on batteries.

In mountaineering we use them quite a lot, for example when navigating a cliff face we use them to find the start point of the climb/route, where bivi spots are etc, also for checking you are at the correct summit point when at the summit (when there’s no trig point) the gps ones are way better for accuracy when using them for mountaineering as the whole air pressure thing becomes a lot more noticeable when your hanging around and not moving at belays.

I’ve been following your channel for a while, I really enjoy your channel and content, love seeing the country side across the pond, looks awesome, also, I have learned so much with your tutorials, I’ve applied the knowledge, it’s an awesome feeling knowing that I haven’t got lost, yet! 🤣. Thank you so much for sharing your knowledge. From Washington state, USA. 👍🏽👍🏽👍🏽🇺🇸🇺🇸🇺🇸❤️👊🏿

50 years ago my survey boss had a barometer/altimeter in a big wooden box that we’d calibrate at post office elevation markers. I think it read to ten feet increments and it worked great for figuring out where you were in the mountains if you had a good topo map.
