I'm replacing the batteries in an old ELT this March in my Discus CS. Alternately, I was thinking of installing a fully self contained ELT with GPS.

Looking for advice on what others are doing including manufacturers and models, antenna placement issues and practicality.

Thanks in advance!

The older ELTs do not communicate with the newer satellite systems (406MHz) and the older 121.5 frequency is unmonitored, except by ground stations.
