> As has been posted here, The SPOT has a very high signal failure rate and doesn't tell you for sure if a signal has been successfully sent (not 100% sure of last....).
A blinking light on the SPOT unit indicates that it transmitted a signal. However, it has NO way of indicating that a satellite was overhead in view of the unit and received the transmission.
The failure rate in the mountains is very often due to the non-receipt of signal.
So often, SPOT users don't realize that they should leave the unit on for at least 30 minutes AFTER pressing the OK button, to help insure that a message gets out. If they're in a tall tree area, or a deep canyon, they could transmit repeatedly, and a signal never get out.
