Rescue Me:
Accusat Is Our Top PLB
It’s small, light, strobe equipped and the price is right.
With 121.5 Mhz ELTs on the way out, any one of these
gadgets can substitute for a 406 ELT—to a degree.

mergency locator transmitters
(ELTs) are one piece of equip-
ment airplane owners love to
hate. They don’t work very well and
they always seem to need replacement
batteries. Beginning next year, the gov-
ernment will cease satellite monitor-
ing of 121.5 MHz ELTs, making what
didn’t work that well to begin with
instantly all but useless.
Rather than invest as much as
$4000 in a new 406 MHz ELT, one
option owners have asked us about is
carrying one of the new 406 MHz,
GPS-enhanced portable locator
beacons or PLBs. They’re relatively
inexpensive, have a good record thus
far and can do double duty as an
ELT and a rescue-me beacon for the
car, the boat or outdoor activities of
all kinds. While this makes sense,
there are some limitations. Read on.
On February 1, 2009, COSPAS-
SARSAT, the international organiza-
tion formed to oversee the ELT sat-
ellite-monitoring network, will stop
listening for the 121.5
and 243.0 MHz signals
from traditional ELTs. A new
ELT standard (TSO C126) using
digital technology and 406.025
MHz is a huge step forward, but
these aren’t required equipment.
Yet. The FAA so far has refused to
expand the ELT requirement to
embrace 406 ELTs and until prices
for these come down from the
flight levels, PLBs remain
an attractive alternative.
We looked at five cur-
rent-generation mod-
els from five dif-
ferent manufacturers.
While they all perform the
same basic task—broadcasting your
location with a GPS fix encoded—
there are differences between them.
Worth noting here is that the
oversight agencies take a dim view
of setting these things off willy-nilly
to see if they work, thus we were
unable to test them in the heat of
battle. For that reason, our evalua-
tions are based on examination of
the units and their specifications
and interviews with the manufac-
turers. For a detailed live test of
PLBs, we recommend reading a re-
port on the trials conducted by the
Equipped to Survive Foundation at
www.equipped.org. New models,
including some covered here, have
been introduced since that test was
conducted.
OVERVIEW
Current-generation PLBs are basi-
cally a portable 406 ELT without
the crash-impact activation feature.
You have to switch it on manually,
something which involves extend-
ing an antenna and pressing a
button. PLB designs are of two basic
types: With or without a built-in
