I had a similar experience with a friend and a SPOT.
After several days of regular updates it just didn't update. I waited 24hrs and called the coasties and gave them the last position. It turned out they had hit something and were busy trying to stay ahead of the inflow during some very nasty
weather. They weren't sinking but were in trouble and were several hundred miles from the last updated position. The coasties had a plane on regular patrol in the area and found them within about 7hrs.
The coasties were, to a man, expert, polite and effective. I was passed from
Houston to
New Orleans to Tampa over the 24hrs I was dealing with them and never had to repeat any of the info I gave them. They also didn't, at my request, call his aging parents avoiding unnecessarily causing them any upset. They also called me back and informed me of the finding of my friend and put my mind at ease by telling me the EXACT situation on board as they new it from being on site. George called me several hours later when he arrived back in
cell phone range.
The people at SPOT however were idiots. I called their number and it seemed to me the guy on the other end just didn't get the idea that the reason I called was that people using their product might be in
danger. His attitude was "ho-hum, ya whatever". He sounded about 18 and none to bright. There is apparently no way to check if the Spot has stopped because it hasn't been updated or it has sunk.
The coasties didn't seem too impressed with SPOT and told me they really prefer if you use an
EPIRB for emergencies and didn't count on the update on your SPOT to always do what it's supposed to. They apparently get a lot of false emergencies with these things because they don't get used properly.
That may be an operator/customer
malfunction but it would seem to me they need to
work on the system to be sure they are not overloading an already overloaded USCG.
It seems these things(SPOT) are supposed to be used to help keep the home bodies assured of your
safety when they may actually cause the opposite...........m
