Beacons in the Outdoors a good article by Mountaineering Council Of Scotland and a Video by Lyle Brotherton.

I am often asked about the use of Personal Locator Beacons in the Outdoors and I am no “techy geek” but have seen them about and done simple trials on them in the past in my RAF Mountain Rescue Days.(Always at the forefront of technology 1973)

The article by Heather Morning talks you through many of your questions. I did work in the ARCC at Kinloss and the MCC (Mission Control Centre) was part of our remit. I would say about 90% in these days were false alarms many going off through various problems/misuse. All alerts had to be actioned and often the owner had sold the boat, plane or beacon and the beacon was not registered . This involved many hours of detective work  by the MCC they did a marvellous job and needed to chase every false alarm! Yet we had some great results from ships, planes and solo walkers in the poles, School groups and walkers.  Beacons are not new and have been use by the Aircraft Industry, ships and the military for many years.  There has been a big push for there use in the Outdoors and I have seen a few on the hills  recently mainly by solo walkers.   This excellent article may give you a better understanding of another tool available but it is not a substitute for common sense! Make sure if you have one it is registered and serviced regularly.

Heather Morning – Mountain Safety Adviser at the Mountaineering Council of Scotland – outlines the role of Personal Locator Beacons and similar products in mountain safety

Mountaineering news this winter has been dominated by two massive searches for people who went missing on Ben Nevis and in the Cairngorms. These searches, involving hundreds of man-hours in searching huge areas of rough and mountainous terrain, have highlighted the importance of letting people know where you are going in the mountains – especially when travelling alone.

But it’s not always possible, and sometimes plans have to change.

One solution increasingly being taken up by outdoor people is to take advantage of satellite technology, using Personal Locator Beacons (PLBs) or Satellite Emergency Notification Devices (SENDs).
Both have considerable advantages, but also limitations and pitfalls, so it’s important to know some of the basics before jumping in.


What are PLBs and how do they work?
A PLB is primarily a life-saving device, similar to the size of a mobile phone, which radios distress signals to orbiting weather satellites. Once triggered, the PLB will alert the emergency services to your exact location. Satellite technology ensures that PLBs are a more reliable way of calling for help than mobile phone, as they only need a clear view of the sky, unlike a mobile phone which relies on a signal from a land based transmitter. PLBs do not require an annual subscription.

What are Satellite Emergency Notification Devices and how do they work?
SENDs – the SPOT Messenger is probably the best known of these – are not just an emergency device. Besides sending an SOS distress message to the International Emergency Response Co-ordination Centre in Houston, Texas, SENDs can notify friends and family with short, pre-arranged status messages, accompanied always with your GPS positon. Users of SENDs must have an annual service plan or they do not function. They work in many areas of the world, but there are some significant gaps.

Do you need a PLB or SEND?
If you head out into the mountains alone, particularly in areas where mobile phone reception is either poor or non-existent, then one of these devices could save your life.

Different hill users have different needs. If you habitually go out alone, the SEND’s advantage is that you can turn on the tracking function and even if you fall and are unconscious, your position is logged – provided that you have told your Emergency Point of Contact that you are out and about and want them to keep an occasional eye on you. If you are looking for a handy device to track your route and update family and friends, the SEND is the tool for the job.

If you’re looking for an emergency transmitter that will notify emergency services of your distress, and which will work anywhere in the world – and which has the facility for SAR helicopters to ‘home in’ to it – a PLB is the most reliable choice. But remember, a PLB has to be manually activated, so if you or your party fall and are unconscious or are avalanched and buried, then you may be unable to access or activate the device.

Some important do’s and don’ts for users of PLB & SENDs
It is essential that you register your beacon with the UK Distress & Security Beacon Registry. This is free and a simple job, providing the emergency services with up to three Emergency Point of Contact details should your unit ever be triggered.
If you do not register your unit then the emergency services will still respond, however, without the Emergency Point of Contact details the response may be significantly delayed.
It is estimated that over 50% of all UK-coded beacons have not been registered.
It is essential that you only activate your emergency beacon in a life-threatening situation, when you are unable to ‘self-rescue’. Be aware that your call may divert lifesaving resources away from other people in dire need of help.
If you activate your beacon, ensure it is in a position where it has a clear view of the sky to maximise its potential of being ‘seen’ by passing satellites.
Once you trigger your PLB you should ideally remain in the same location. Your PLB transmits a half-second data burst every 50 seconds. If you move after activating your PLB, the emergency services may initially be sent to the wrong location, resulting in confusion and delay.
If you have activated your PLB, do not switch it off.
For SENDs, be aware that, once you have triggered your beacon it may take up to 30 minutes to get a signal out, depending on the current position of passing satellites.
The vast majority of beacons triggered in the UK in 2015 were false alarms that wasted a huge amount of time. The danger of false alerts diverting search and rescue resources from genuine incidents should always be borne in mind.

How much do PLBs and SENDs cost?
PLB’s are available from about £170 upwards.
SENDs retail at £140 upwards depending on the model, plus an annual service plan typically starting at £100 for the basic service.

Thanks to Heather and the Mountaineering Council Of Scotland for the use of this article. Also to Tom Taylor and Lyle Brotherton for use of and advice.

My pal Lyle Brotherton has done a vidoe on PLB

Jim Fraser – Lyle mentions being able to operate the device in low light or when blinded (or older users losing their glasses!). Good point, and a tick in the box for the PLB since it has a single function with simple operation. If you have a British registered PLB then the RAF and MCA are watching over you wherever you are in the world: no charge.

    As a solo walker out in the Scottish hills in all seasons and often on less frequented hills I have carried a SPOT GEN3 (a SEND) for the last 12 months. Hope never to have to use the thing in anger but it provides real re-assurance to my wife back home that in the event that I was involved in an incident and couldn’t self-rescue that I could alert MRT saving hours of valuable time. The device weighs next to nothing and although there is an annual subscription – the cost is, in the grand scheme of things, good value for the comfort it provides. I’d recommend them to anyone who goes out alone.

    If you’re worried about safety the simple solution is to stay at home.

    The whole point of wild places is that you have to rely on your own abilities and knowledge. Where is the adventure if we try to eliminate all risk?

      This was just a insight into the use of Beacons ! We all have a choice that is our right as individuals. Each to there own but do not forget those who wait at home for our return ?

    In reply to Noel – “If you are worried about safety the simple solution is to sty at home” – but isn’t it often said that more accidents happen at home than anywhere else!
    More seriously, in my mind, taking a SPOT GEN3 with me isn’t a sign of worry or weakness or trying to eliminate risk. I’d compare it to ensuring that I have an inflated spare tyre in my car when I venture out. And yes – I am experienced and self-reliant (as a solo walker you simply must be) and careful about tying to always ensure I get home safely every time I’m out but the reality is that ‘bad stuff’ happens from time to time even to the best of walkers/climbers (not that I’m claiming that status) and it seems a sensible and prudent back-up as well as providing family with useful comfort. And all for a one-off purchase of c£100 and a monthly subscription of about £8 a month (which is a lot less than I usually spend on petrol when out).
