These devices do not actually allow you to have a conversation as such but
signals from distress beacons can be picked up by satellites and passing
aircraft. They are to be used only in an emergency situation. They should
be correctly stowed so they do not go off accidentally and waste valuable
search and rescue resources. Penalties do apply for misuse.
There are three types:-
Emergency Position Indicating Radio Beacons usually used by marine craft.
PLB– pocket size
Personal Locator Beacon
activated electronic locator transmitters, mainly for aircraft.
The definition of ‘distress situation’ varies
from country to country but it relates to the
safety of human life.
A fact sheet No. 22 is available from the
Australian Communications and Media Authority
(ACMA). The ACMA indicate that if vehicles and
bushwalkers in remote parts of Australia carry a
distress beacon it should be the 406 MHz PLB
The 406MHz distress beacons are more accurate,
are detected more quickly and identify their
owner. Also the 406MHz operating beacons are
compatible with Cospas-Sarsat Satellite System
that receives distress signals as it orbits the
The beacon should only be activated in a
distress situation. The fact sheet defines a
‘distress situation’ as:-
A distress situation is generally defined as one
in which a person or persons face grave and
imminent danger and require immediate
assistance. On land such situations might
the need for urgent medical evacuation;
mechanical breakdown where food and water
supplies can not be replenished;
being lost with little hope of reaching
outside assistance before food and water
supplies are finished; and
similar life-threatening situations.
Each situation is unique and common sense and
good judgment need to be exercised.
These lightweight personal EPIRB
devices are ideal for camping, bushwalking or
4WD in the outback.
Once activated the PLB will emit
a homing signal for emergency services to locate

Perisher Valley, Khancoban and Tumut. EPIRBS can also be

PERSONAL LOCATION TRACKERS
As an EPIRB can only be used in a ‘distress situation’
defined above you may want this personal location tracker to have in
addition to an EPIRB. Whereas the personal locator beacon (PLB) can be used
on a public-access satellite network there is now a product Spot GPS
Personal Location Tracker which uses the commercially owned Globalstar
You can hire the personal location tracker or purchase one
outright. Costs include the unit itself, the GPS subscription cost and a
fee for the tracking functionality. Search and rescue insurance can also be
purchased at the initial activation of the personal location tracker which
is cheaper than if you purchase it later.
