People in this discussion should stop to read the excellent FAQs about
the ELT requirement on the SRA website:

http://sailplane-racing.org/Rules/CR...T%20FAQ%20.htm

It explains the rationale for the rule quite clearly. Briefly, the
requirement is there to protect contest organizers, and at their
request, rather than to force unwanted protection on pilots. Imagine
running a contest, someone goes missing, and day after day passes.
That's also why the rules require a mounted, impact-activated device.
