(Sorry for the previous blank post).

I used SPOT all last flying season and never found significant loss of
tracking function for my needs. I "secured" it to my parachute chest
or shoulder strap, either of which worked well enough for all purposes
but bailout (my conjecture only). When cooler weather arrived, I
secured it in a zippered shoulder pocket of my down jacket, also
experiencing no fall-off in tracking, and maybe with some increased
modicum of security that it would not be lost during a bailout. The
chest and shoulder positions are both relatively vertical at rest but
change with ambient pitch and roll as noted. Secure attachment is a
priority goal for this season.

I understand the interest in using SPOT for tracking gliders, however,
it was intended to track people and, should I depart my glider, I need
to have SPOT depart with me. I could care less if they find the
glider after that. If I don't depart the glider when it suffers an
adverse encounter with terrain, I will need SPOT within forearm's
reach or less if it is to be of any use to me. Dale Kramer's
experience was the genesis for this opinion. Finally, if I am unable
to activate SPOT, it's highly probable that urgent S&R will prove
unnecessary.
