    As a sailor I struggle to see why you need GPS on featured land at all.

    As someone who learned their basic navigation on a boat too ..
    Whiteout (for example).

    Plus, in some circumstances, the need for more accuracy ('which side of
    the hedge'😉 than you can get by more antique methods - the one I've
    quoted before is finding a one-plank footbridge in the bottom of an
    wooded & overgrown gully, where being able to hit the previously
    recorded position again to +/- 2m can save you hours of climbing up and
    down.

    On flat ground maybe. You'd be pretty brave to trust GPS for blind nav
    on a mountain in whiteout.

    Yes. You've won me round with that answer.

    Quite a lot of mountains /are/ flat in fairly large chunks. The
    Cairngorm Plateau is an obvious example, and just the sort of place in
    whiteout where a GPS would be particularly handy. Essential, no, but
    potentially very, very handy, certainly.

    Yes, If all I had was position, but typically I have loaded paths,
    tracks, waypoints, summits, trig points, and contours. I still wouldn't
    step forward if I couldn't see the ground underneath me .. well, maybe
    if I was on a 'backtrack' with +/- 2m accuracy, and KNEW I'd never gone
    anywhere near a precipice. 8>.

    'Here you are' (from a GPS) plus a decent map is still handy, except
    even decent maps can't really be trusted when the contour lines start to
    cross. 8>.

    Having said that, and since you've raised the point, I do consider it
    pretty daft to go out without one, and if I was a member of an MRT
    that had to spend ages searching in dangerous conditions for someone
    who could have been located easily if they'd had the means of passing
    on a GR I'd be pretty annoyed.

    If and when a GPS can be got for as little as a compass then you may
    have a point. Until then, a GPS will continue to be, for me, an
    unjustifiable luxury, something which might be of some benefit in
    certain circumstances.

    On the other hand, the combination of GPS plus mobile phone has done
    more than anything else in recent years to reduce the self-reliance of
    those on the hill. Why bother learning to navigate if you can just
    follow the arrow on the GPS? And if that fails, just phone MRT.

    Congratulations: I foolishly categorised two GPS use scenarios as
    mountain and flat. In fact I should have pointed out that they are in
    no way mutually exclusive and that when I said mountain I meant
    mountain near bits with potential for getting hurt. Good show, well
    batted.

    Can =ANYONE= do 'traditional navigation' in a whiteout?

    Yes. And anyone who can't shouldn't be on the hill in winter IMHO.

    I wouldn't be caught dead up a serious hill without a GPS

    You'd not want to go walking with us then, of the 2 dozen or so who go
    walking regularly, I only know of 2 who have GPSs.

    That assumes you know where you start from. If you don't, in a
    whiteout, you am stuffed.

    So what do you do when you're in a whiteout and your GPS dies? It
    sounds from what you've been saying like you won't know from the map
    exactly where you are. And that is the source of your problems.

    Whether you use a compass or a GPS, you should always know roughly
    where you are on the map. And if bad weather is approaching, then you
    should make sure you know *exactly* where you are.

    Quoted message said:

    In my book 'traditional navigation' starts
    with triangulation to discover your position - maybe other people have
    different books. 8>.

    Why would traditional navigation start from the assumption that you've
    already failed and are lost? The point of navigation, traditional or
    high tech, is not to get lost in the first place.

    So do you really think that the majority of the nation's walkers are
    "pretty daft"? Strikes me as rather strong!

    Well I'm not talking about a leisurely bimble down to the woods, but
    if people are walking into areas covered by MRTs, when the conditions
    (topographical, weather, degree of experience etc i.e. the situation
    taken in the round) create a real possiblity of suffering harm if lost
    then yes - on the whole I think it's pretty daft not to take one.

    I don't see them as essential, but they cost little, weigh little,
    take up hardly any space yet have the potential to save a life. My own
    view is that it's pretty daft not to take such an easy precaution that
    has the potential to be so extremely helpful, assuming, of course,
    that the person in question would wish to be rescued if lost. If they
    wouldn't want to be rescued then there'd be no point in taking one. I
    wouldn't dream of attempting to *tell* anyone else what to carry
    though.

    Though among the members of MRTs I know personally there doesn't seem to
    be any such sentiment, at least that they're readily admitting to..

    Quoted message said:

    Istm that if we expect the volunteers to turn out and help us in times
    of crisis then the least we can do is take cheap and simple
    precautions to keep the risk to them as low as possible.

    Yet it is still the case that I have /never/ heard an MRT member (and I
    know a few) state anything along the lines of thinking it "daft" not to
    take a GPS with you every time. ISTM that you're making rather big
    assumptions about the opinions of a lot of volunteers, who only need to
    change their mind to stop being volunteers, after all.

    I made no assumption at all about the opinion of volunteers. I said
    that *I* would be pretty annoyed in those circumstances.

    I entirely agree with you that it's up to the individual to decide

    (phone, GPS) can be enormously helpful.

    Who is trying to deny any such thing though?

    Well you, for a start, seem to be unwilling to acknowledge that on the
    occasion that we've been talking about it would have been very helpful
    for the blokes in question to have been able to give the MR a grid
    reference.

    Quoted message said:


    The crucial difference is between thinking something may be helpful and
    thinking one is morally obliged to carry it. The MRTs don't, AFAICT,
    feel it is a case of the latter.

    Again, I've not said anything about what members of MRTs think.

    I wonder if this sort of debate went on when maps and compasses were
    first introduced? Devil's spawn, etc.... 🙂

    At a talk from my neighbour and MRT leader Alfie Ingram I was at about
    MRT work, he started with a couple of slides. One was of someone in All
    The Right Gear with map and compass and another was a shepherd in tweeds
    and wellies with anything he'd need in his pockets. No map, no compass,
    no waterproofs, both headed out into similar terrain. Next point was it
    was almost always the first sort who needed the services of the MRT.
    Maps and compasses are certainly not Must Haves if you know the area
    you're in. Typically they are regarded as Must Haves because
    recreational walkers are often not intimately acquainted with the area
    they are in, but again we must avoid generalising a typical case to all
    cases.

    Quoted message said:

    Um... I know you're thinking aloud, but I really don't see how you get
    there from the simple observation that the availability of a grid
    reference would have been of assistance to the MR team last week!

    It's the very thin end of a thick wedge.

    No it isn't. You'll be calling me a Nazi next! 🙂

    Quoted message said:

    Higher up you've been saying
    it's (IYHO) daft not to take a GPS, next step on from that is it becomes
    a widespread feeling amongst Joe Public,

    Don't be silly. Joe Public has shown no signs yet of feeling obliged
    to adopt my opinions. Joe Public won't have an opinoin on it at all,
    as this question is relevant to hardly anyone out there. Walkers who
    need to navigate will eventually have an opinion, but I'm not holding
    my breath waiting for the walking public to email me with enquiries
    about what to think!

    Quoted message said:

    then it becomes a contributory
    negligence claim by an insurance company, etc. etc.

    People make all sorts of daft claims after watching too much LA Law.
    Courts throw them out on a daily basis: this isn't America - we have
    judges deciding those issues, not juries.

    That's not to say that it couldn't be negligent not to carry one in
    appropriate cirucmstances, of course. I'm sure this NG would
    collectively have no difficulty in identifying circumstances in which
    it would be considered negligent not to take a map and compass. The
    GPS is a tool just like the map and compass.

    Quoted message said:


    We've had in the last few years the spectres of compulsory insurance and
    suspension of access rights at night or in bad weather, so it's wrong to
    think this sort of idea can't get thrown about in some very high places.

    Well people will discuss these ideas, and we're all entitled to
    opinions. I've told you mine, but no-one else out there need feel
    obliged to adopt it 🙂

    Nor would I. People who can navigate will navigate though. Do you
    think that navigation at night must be impossible without GPS because
    you can't see anything much? Do you think everyone got lost in whiteout
    before GPS?

    I was doing a winter experience day for the Uni club a few years ago in
    the Northern Corries. We ended up in whiteout, someone asked me why we
    weren't turning back as we couldn't see anything so surely it was
    madness? I told him how what we'd come to in about x minutes and y
    meters and in about x minutes and y meters we came to it just like I
    said. How could I do that with just a map, compass and brain? It's not
    /that/ hard with practise.

    If they suspected that they didn't have the experience to walk out
    from a hostile environment then it's common sense to me that they
    should have equipped themselves to be able sit it out

    How many of us go out into the hills expecting to get into a position
    we can't escape from? And how many take sufficient spare kit with
    them to be able to survive in comfort for not one but two or more
    unplanned nights?

    I used to go out onto the Scottish winter hills (alone) carrying all
    sorts of rubbish - stove, fuel, sleeping bag, shovel, flares, kitchen
    sink, all for a day walk. Until a friend of a friend, a guide at
    Glenmore, pointed out that I was carrying twice as much weight as he
    did, even including the 'group' equipment he took! Thus slowing me
    down considerably, and increasing the chances of the emergency
    occurring in the first place.

    Then you have a much lower worry threshold than an awfully large number
    of people who persist in coming back from Serious Hills without having
    or using GPS units. Was hillwalking /really/ considered such a colossal
    risk activity before the portable GPS receiver?

    There are always going to be idiots, but that doesn't make the GPS any
    less useful a tool for the majority i.e. the non-idiots.

    From time to time I browse over to MRT websites and read through
    accident reports. I've no done it for a while, but I've not got the
    impression that most call outs occur as the result of idiocy on the
    hill. The impression I have is that most of them (and I'm thinking of
    the Lakes, here - not other places) seem to occur when people fall and
    break a limb, or suffer a heart attack or something similar. I'll go
    and have another look later this evening if I remember.

    Of course, but mistakes do happen and people do get lost. That will
    continue to happen. It's part of the reason the MRTs exist.

    Last week 4 blokes got lost on the Cairngorms. It sounds from the
    press reports as though they didn't know where they were. They rang
    the MR for rescue, and the MR had to search a wide area to find them.
    Do you not agree that in that situation, since it was actually
    happening - the mistake having already been made - it would have been
    helpful for them to have been able to send the MR a grid reference?

    It's all very well saying they shouldn't have been there, but they
    *were* there.

    Well the 1 in 10,000,000 person stupid enough to do that is unlikely

    Ha! If only that were true. Unfortunately I suspect many new users who
    may not be as well informed as they think they are will tend to follow
    the GPS track blindly at first - not least because they're so fascinated
    by the way the track unfolds on the screen they forget to lift their
    eyes every now and then to see where they're actually going.
