In recent years, carrying a Personal Locator Beacon (PLB) has become widely recommended within the hiking community. I strongly support this. In fact, I believe every individual hiker should carry their own PLB on every hike. A PLB can be lifesaving in genuine emergencies, particularly in Australian terrain where mobile coverage is unreliable or non-existent.
However, a PLB is not a strategy. It is not preparation. It is not a substitute for skills, judgement, or planning. It is a last-resort emergency activation device. Understanding that distinction is essential if we want to strengthen safety rather than weaken it.
This article explains where PLBs fit within a layered safety model, and why self-reliance remains the foundation of responsible hiking.
What a PLB is designed to do
A PLB has one core purpose. When activated in a life-threatening emergency, it transmits a distress signal to rescue coordination authorities. It tells Search and Rescue teams that you need urgent assistance and provides your location.
It does not:
- Navigate for you
- Assess weather risks
- Prevent dehydration
- Treat injuries
- Replace sound decision-making
It is designed for situations where self-management is no longer possible. It is the final layer in a safety system. That final layer should be available to every individual, not shared as a group assumption.
The real issue is misplaced confidence
The problem is not that hikers carry PLBs. The problem arises when the presence of a PLB creates misplaced confidence.
There is growing evidence that many Australians lack confidence in handling common outdoor challenges. Surveys have shown limited preparedness in navigation, first aid, and emergency response. In this context, technology can feel reassuring. Apps provide GPS tracking and mapped trails. PLBs offer a direct link to rescue.
But reassurance is not the same as capability.
If planning becomes secondary because “I have a PLB,” risk increases rather than decreases. Technology does not eliminate hazard. It only assists once something has already gone wrong.
Safety works in layers
Effective hiking safety operates through layered systems. Each layer reduces risk before the next is needed. A PLB sits at the final layer, but it only works effectively when the layers beneath it are strong.
Layer 1: Planning and preparation
Route research, terrain assessment, weather monitoring, realistic time estimates, and physical readiness. This includes thorough planning and preparation before you leave home.
Layer 2: Navigation competence
Understanding how to read terrain, interpret a topographic map, and use a compass. Digital mapping tools are valuable, but foundational navigation skills remain essential when batteries fail or signals drop.
Layer 3: Equipment and redundancy
Carrying appropriate gear beyond a phone and beacon. The Ten Essentials framework exists for a reason. Clothing, insulation, first aid supplies, food, water, and lighting all reduce risk before an emergency escalates.
Layer 4: Decision-making and judgement
Recognising when to turn around. Adjusting plans due to weather. Managing fatigue. Avoiding terrain traps. This layer prevents minor issues from becoming major incidents.
Layer 5: Communication and trip intentions
Leaving a plan with a trusted contact using a trip intentions form ensures that delayed returns trigger appropriate follow-up.
Layer 6: Emergency activation
Only when the previous layers fail or an unavoidable accident occurs does the PLB become critical. That final safeguard should be accessible to every individual on the hike.
Common misconceptions about PLBs
“I can always press the button if something goes wrong.”
Rescue activation is not instantaneous. Terrain, weather, and aircraft availability influence response time. In many environments, you may need to self-manage for hours or longer before assistance arrives.
“The app shows the trail, so I do not need map skills.”
GPS tracks can drift, maps can be outdated, and phone batteries deplete. Understanding terrain features and maintaining situational awareness reduces reliance on a single device.
“A PLB makes remote hiking safe.”
Remote hiking carries inherent risks. A PLB mitigates consequences after an emergency has occurred. It does not reduce the likelihood of that emergency in the first place.
Why every hiker should carry a PLB
A PLB is a last-resort device. That does not mean it should be rare equipment. It means it should sit at the final layer of every individual’s safety system.
I believe every person on every hike should carry their own PLB, regardless of group size or perceived difficulty. Accidents are unpredictable. Even on short or familiar walks, incidents can occur that immediately remove your ability to communicate.
Incidents do not only occur on remote multi-day expeditions. A simple slip on a short trail can result in a fractured ankle. Heat exhaustion can develop on familiar tracks. A fall into a gully can leave someone unable to move or access their phone. A snakebite, even on a well-used path, can rapidly impair mobility and decision-making, particularly if you are alone or separated from your group. In many parts of Australia, mobile coverage is unreliable even close to towns.
Relying on a single PLB shared across a group assumes the person carrying it remains conscious, mobile, and accessible. That assumption does not always hold. Separation can occur. A fall can incapacitate one member while others are out of sight. If only one person carries the beacon, the entire group’s access to emergency activation depends on that individual.
Even when hiking together, my wife and I each carry our own PLB. Not because we expect something to go wrong, but because layered safety means individual redundancy. Every member of a group should remain capable of activating emergency assistance independently if required.
Carrying a PLB does not weaken self-reliance. It strengthens the final safeguard when all other layers have been exhausted.
Self-reliance reduces rescue activation
Many Search and Rescue callouts are not the result of catastrophic accidents. They often stem from preventable issues:
- Poor route planning
- Underestimating distance or terrain difficulty
- Inadequate water management
- Navigation errors
- Weather misjudgment
As explored in my article on common reasons hikers get lost, many incidents develop gradually rather than suddenly.
Strengthening self-reliance reduces unnecessary rescues. It protects volunteer responders, reduces risk to rescue crews, and ensures that emergency resources remain available for genuine life-threatening situations.
Self-reliance is not about refusing help. It is about minimising avoidable escalation.
Technology as a tool, not a substitute
Technology has improved hiking safety significantly. GPS devices increase situational awareness. Weather forecasting is more accessible. PLBs provide critical emergency connectivity.
Technology functions best when layered over competence.
A phone app should support navigation skills.
A PLB should support emergency planning.
A satellite communicator should support clear trip intentions.
None of them replace foundational knowledge.
The foundation remains preparation
By prioritising self-reliance, you move from passive dependence to active risk management. Preparation reduces the likelihood of needing rescue. A PLB reduces the consequences if rescue becomes unavoidable.
- Knowledge allows informed decisions.
- Preparation builds confidence grounded in realism.
- Skill reduces avoidable mistakes.
- Humility encourages conservative judgement.
A PLB remains a last-resort device. It should be carried by every individual, and used rarely.
Your primary safety system is still your planning, your skills, your equipment choices, and your decision-making on the ground. The beacon simply ensures that if every other layer fails, you are not without options.
Carry the beacon.
Build the competence.
Treat the device as a safety net, not a shortcut.
What are some essential survival skills you think every hiker should master before hitting the trails, aside from relying on tech?
Pausing often to a/ enjoy the place, birds, bugs etc, b/ read the landscape – see how things are connected, general lie of the land, potential risks / impediments ahead, mental snapshots of trail / interesting tree / rock outcrop etc, and c/ keep an eye on the time / progress rate.
Ben Marshall this is an important point. Pausing to read the landscape known your surroundings, notice changes in terrain, track time and progress, and stay mentally oriented is a core part of self-reliance. Apps and PLBs can support that awareness, but they can’t replace it. What you’re describing is exactly the kind of situational awareness that keeps small issues from becoming big ones.
Trail Hiking Australia basic route planning is very important, track notes, study maps paper or digital. Be familiar with the terrain you’re going into. Basic essentials for a day out in the bush, first aid kit , enough water and not just a 600ml bottle thats carried in your Hand. Food and snacks that will give you energy and Maybe a head lamp
Norman Herfurth well said. Route planning, reading track notes, understanding the terrain, and carrying the basics like first aid, enough water, food, and a headlamp are simple things that prevent a lot of avoidable problems. None of it is complicated, but it all matters.
Trail Hiking one that I’m working on is using a compass and paper map to learn manual navigation! Can’t always rely on devices.
Isabel Reid that’s a lot of fun. Hope it’s going well.
How to plan! Basics such as – if you’re planning a one day hike, enough food and water for 3, telling people where you’re going (timelines).
Juzee Celentane exactly. Simple planning habits like this make a huge difference. Extra food and water, realistic timelines, and letting someone know where you’re going are basic, low-effort steps that prevent many emergencies before they start.
Trail Hiking Australia the old “it ain’t rocket science!”
Iam very happy to stick to my GME , PLB . And basic self reliance skills.
Norman Herfurth that’s exactly the balance I’m talking about. Carry the PLB, use the tech you trust, and back it up with basic self-reliance skills. It’s not either/or. It’s layers of safety.
Knowing what clothing and protection you need, especially in cold wet conditions. Being able to recognise you’re getting cold. At that point stop, set up your tent, put some warm dry clothes on, get in your sleeping bag, and warm up. Eat some food that’ll always helps.
Gerard White this is a really important point. Knowing what clothing to carry, recognising when you’re getting cold, and stopping early to manage it is critical. Cold, wet conditions don’t usually become dangerous suddenly. They become dangerous when early warning signs are ignored. Food, dry layers, and taking time to warm up make known difference.
Gerard White and understanding the clinical signs and symptoms of hypothermia!
Love this. Self reliance should be a subject at school.
Assurance First Aid Kits I agree. Those skills translate directly to safer time outdoors, but they also build confidence, awareness, and decision-making in everyday life.
Self first-aid in a crisis.
Snake bite, broken ankle, wrist or collarbone. Eye irritations. Purifying water
Jim Bannan absolutely. First aid skills are critical in those moments before help is available. Knowing how to manage a snake bite, stabilise a fracture, deal with eye injuries, or purify water can make the difference between a manageable situation and a serious emergency. A PLB can summon help, but it can’t provide care in the meantime.
Good old paper map, especially a Topo Map, with compass and basic map reading skills.
Bushexplorers absolutely. A paper topo map and compass don’t rely on batteries or signal, and basic map-reading skills give you constant situational awareness. Digital maps are great tools, but they work best when backed up by those fundamentals.
I think this writers probably unplugged his computer and only writes with a fountain pen out of principle.
Daniel Hill Not at all. I use tech on every hike, including apps and a PLB. The point is that technology should support planning and skills, not replace them. That distinction is what the article is about.
Trail Hiking Australia it’s ok I was just kidding.
Daniel Hill funny. The article literally supports using technology. Reading skills still matter too, apparently.
Sam Herald i didn’t read the article but not many people just start a massive multi day hike in tough conditions in only shorts and thongs with a plb stuck in their back pocket
Daniel Hill PLBs aren’t just valuable for multi-day hikes. They are used and activated on day hikes too. Probably more often than in overnight or multi-day hikes.
Trail Hiking Australia I know, a pbl saved my dads life on a day hike with him up mt Eliza where he fell 30 meters bouncing off boulders and ended up unconscious with broken bones and bad concussion. Luckily on the way up I confirmed I knew how to use the device.
Daniel Hill wow. That was fortunate. Glad he’s ok.
There was a legitimate rescue for a guy who i quote felt “fatigued” on a hill, that takes me 40mins to walk down. We as a society are getting rather concerning.
It’s difficult to teach orientation skills and risk management except through experience and engagement. This can be done with experienced groups or people.
always consider the worst case and how your kit will protect you until help arrives or you can make it out.
Orientation and planning the route and exit strategies – knowing where you are, and what options you have, alternate exits, critical decision points, etc.
How to manage yourself in stressful situations.
There’s more to say on time management and not underestimating terrain and
planning yourself into trouble etc.
Hisham Mstfa This is really well put. A lot of these skills are hard to teach abstractly. They come from experience, mentorship, and learning alongside others who have spent time in these environments.
Thinking in terms of worst case, exit options, decision points, and how you manage stress is exactly what turns planning into real-world judgement.
PLBs. They don’t staunch the bleeding, provide warmth or filter water.
They can be helpful in locating the body.
Nicholas Hayes that’s the point some people miss. A PLB can help bring assistance, but it doesn’t manage the situation before help arrives. Having the right knowledge and gear does.
I imagine that’s what the luddites said about seat belts too.
Peter Wood seat belts are a great analogy actually. They’re essential, but they don’t replace safe driving, awareness, or judgement. They’re there for when things go wrong.
True. They are also there to ensure that our loved ones get home safely. The same as PLD etc. No amount of training or experience can prevent bad luck sometimes. Even the hardiest of travellers / hikers / climbers have a horror story. If we want our kids or other loved ones to get home safely then the advent of PLB’s and the like are a good thing.
Peter Wood I agree with you. PLBs are absolutely a good thing and I fully support people carrying them. Accidents and bad luck happen to even the most experienced. My concern isn’t about using PLBs, it’s about when they’re treated as a substitute for preparation, skills, and judgement, rather than a last-resort safety net. Both can and should exist together. That’s what the article is about.
Harking back to my Scout Leader days, definitely reading a map and triangulation.
Mel Palankay those are valuable skills to have. Those skills build real situational awareness and don’t rely on batteries or signal.
Self rescue or die!!
One of the biggest issues that I believe is actually causing fatalities, is a combination of the lack of preparation, lack of appreciation of the terrain and weather, and the belief that a mobile phone is a reliable back country navigational device.
Carry a daypack with enough water and food, carry a small med kit and some clothing to suit the onset of unexpected bad weather. Tell people where you’re going and your expected return time.
Do some more research on the area, the terrain, the climate, trail ratings, any closures etc, check the forecast for at least the next week, sometimes that storm decides to arrive 2 days early.
Carry an actual GPS, or learn to use a map and compass. (Better still, do both) Dont think Apple or Samsung are going to save your butt, especially when there is no service. Plus using gps apps drain your battery faster, especially if using the camera often as well.
Be blunt with your self assessment of your fitness, you’re likely not a teenager anymore.
Don’t be stubborn in your mindset, if it’s too far, or weather is closing in, turn around.
That my 2 cents anyway.
Dan McNab Thanks for sharing this. You’ve covered a lot of the real-world factors that actually lead to trouble on the trail. Preparation, terrain and weather awareness, honest self-assessment, and knowing when to turn back all matter far more than most people realise.
Trail Hiking Australia the self assessment saved me in NZ last year. I had a goal, my secondary goal was 5km, and 900mtrs vertical closer. Once I went above the snowline, I was in a new world for me. So I assessed how I was feeling, and turned around at my secondary goal. Still amazing, and I had everything I needed even if I was caught in a blizzard. But I had fun, the extra trek would have just destroyed me and I wouldn’t have enjoyed it, even if I did make it.
Well i carry the kitchen sink, everything. Even on a 3km hike.
I know we all say don’t rely on your phone etc but something i have found is to trust it when it tells you were you are.
I have been in a couple of situations where i thought, naah, surely not but yes i was where it said i was.
If you don’t mind Darren i can post a link to the video i did about the gear i carry after i sprained my ankle in the bush.
Peter Jolly thanks for sharing that. Carrying extra gear and learning from injuries is how judgement gets built. Phones and GPS can be very accurate when they’re working. The key is not letting them be the only plan.
PLB’s aren’t a tech tool. They are a basic safety piece of kit that every hiker should carry regardless of their experience, planning or knowledge. Too many gungho walkers out there.
Jim Roberts I don’t disagree with you. I fully support PLBs being carried by hikers of all experience levels. My point isn’t that PLBs are optional, it’s that they shouldn’t be treated as a replacement for planning, skills, or judgement. They’re a safety net, not a licence to take on terrain you’re not prepared for.
💯% agree Trail Hiking Australia . I’m a photographer who heads out on long day hikes solo. A portion of my bag is always reserved for ‘worst case scenarios ‘ kit…that is, getting injured, lost or having to spend the night outside alone.
Nathan Brayshaw that kind of preparation is exactly what keeps solo days enjoyable rather than risky. Thanks for sharing.
