I believe it's for situations where you are in immediate life threatening and urgent need of support. The response from the marine rescue surprises me somewhat. It should be your very last resort after you've explored all other options.
I think you should stay close to shore and have appropriate clothing and life rescue devices such as a pfd instead of a plb so that you can swim back whatever the situation.
We've seen a PLB request for help in action and it might take much longer before rescue arrives than you would expect so it might not arrive on time. It's difficult to keep the device out of the water pointing at the sky so they might be looking at the wrong location. Helicopters and boats will be dispatched so very expensive.
I carry a GME MT610G fwiw.
Agreed, it is just a backup to all your other safety precautions.
But the response from marine rescue is NO surprise to me. When a search is eventually called after a person fails to come home, and without an accurate location to search in, hundreds of man-hours can be spent in just one search! And, all too often that will end up being a 'recovery' rather than a 'rescue' mission.
When a PLB is deployed, they immediately have GPS coordinates to start searching, and even if the PLB stops sending a signal, they're at least searching the right area. (Imagine how many targeted searches and quick rescues they could achieve with the amount of resources that are typically utilised in one non-targeted search?)
Furthermore, mine includes a strobe which could attract the attention of any nearby boats. (IDK whether they all do.)
A pfd is great to reduce risk of exhaustion & drowning, although it does little to reduce hypothermia. Another benefit is that a surface search can eventually find the body, in the event you didn't deploy your beacon & the search comes too late!
One of the reasons that some time can elapse between an activation and commencement of a search is that AMSAR will check with contacts listed for your beacon on their database to see whether there may have been an accidental activation, and to verify exactly what they're searching for (eg: windsurfer vs boat). At this point, your contact person might well launch their own rescue mission, if able.
In Australia, you will not be charged for the cost of a search and rescue, so don't worry on that count, and don't even bother feeling guilty about this because a timely beacon activation will save the rescuers' money!
Mine is a KTI, but sadly they're no longer available.
