True enough, but this ignores that the 121.5 / 243 Mhz units are scheduled
to go to a "no response" status from the COPAS / SARSAT in less than 3
years - - replaced by 406 Mhz units.

That's why I limited my comments to the 121.5/243 units,
which were the only ones available when I made my choice.
The 406 units can be localized better, although I still
doubt that the pilot is likely to be very far outside that
area.

Of course the 121.5 Mhz signal will still be useful for search and rescue to
home in on - - if they get notified somehow.

There's no doubt that the 406 is a better option. More
expensive, but the price will fall. As to the personal vs.
mounted issue, I still think mounted is better, but the
question is a bit closer.



The following is worth reading. A GPS-equipped 406 MHz ELT is said to
be accurate to less than 100 yards, without to 1-3 nm. Elsewhere on the
site it mentions that processing of 121.5 MHz & 243 MHz beacons are
ceasing on 1st Feb 2009. If I was buying that would push me towards a
406 MHz ELT.
