TT15 dropped GPS

[Steve Serini]

i was hunting today and one of my collars stopped tracking.
the display showed batt. no GPS but did have Communication.
and it would shock.
when we got back to the truck i turned it off and back on and it showed i had GPS.

They are only a few months old.
anyone else have this happen?
advice?

thanks
Steve

Had it happen to a buddy of mine the other day it did the same thing, he did the same as you turned it off and back on and was good for the rest of the day
