Correct, but you dont need to actually own the current sheet or have on
in your possesion to know that info, do you ?
To calculate the current deviation, you DO need a sheet that is no more
than a few years old.
Or you could ask your mates or you could look it up.
I currently use 2deg, and current rate of change is about 1/4deg per
year.
In 5 years time I might enquire if the rate of change has altered
significantly.
I dont need the very latest map in my possesion to know what the
current magnetic deviation is, do I ?
There are a surprising number of people who think that "It's a National
Park - we can go anywhere".
Yes, and they would have been wrong.
But in practice, in most national parks its not an issue.
No they don't!
If you are following an established track then yes, there will be a
sign. However it's very easy on some to get close to the heart of the
Danger Area without coming anywhere near a sign.
You should tell someone, this is a clear public safety issue.
Are you suggesting that the average tourist (who probably does not have
a map) can idly wander into a danger area without seeing the obvious
signs ?
What exactly are the regulations relating to such areas ?
Can the MOD use these areas based on a principle that they dont have to
mark them on the ground in an obvious way, but can say "its marked on
the latest map mate" ?.
groups (including Scouting groups) on Dartmoor using the red flags as
landmarks to navigate to - they "looked like a good spot to stop for
lunch".
Thats stupidity.
I doubt having the latest map would stop them being stupid.
But do use as recent a sheet
as you can, and check it against the latest for changes. WHSmith is a
great place to spend 40 mins poring over the latest sheets making notes
of the area you are going to.
Yeah sure, and an interesting use of time to those that have the time
Necessary, not.
