From SPOTS website on coverage...
SPOT works around the world, including virtually all of the continental United States, Canada, Mexico, Europe and Australia, portions of South America, Northern Africa, and North-Eastern Asia and hundreds or thousands of miles offshore of these areas. In Russia, the GPS accuracy of your SPOT is limited (degraded) in accordance with Russian regulations restricting the accuracy of GPS performance for devices utilized in Russia.
99% OR BETTER PROBABILIITY OF SUCCESSFULLY SENDING A SINGLE MESSAGE WITHIN 20 MINUTES.
96% TO 99% PROBABILITY OF SUCCESSFULLY SENDING A SINGLE MESSAGE WITHIN 20 MINUTES.
REDUCED OR NO COVERAGE AVAILABLE WITHIN A 20 MINUTE PERIOD.
NO COVERAGE IN THIS AREA.
Last Updated 10/08/2008. Estimated coverage area. Actual coverage may vary. Success rates are forecasts for a SPOT messenger to successfully deliver a single message during a 20-minute period, based on network availability. Additionally, in everyday conditions it is normal for some messages to be blocked by your environment, such as hills or buildings.
That 's why the SPOT Messenger is scheduled to automatically send multiple messages in every mode - giving you excellent overall reliability.
.... They even say it won't work in all places. Would probably get an emergency signal out though to a single satellite but would not have gps coords...
Power on an antenna depends on voltage and current. So if the power difference between the new model and old model are the same for signal strength then they will both work the same. Now if they kept the current the same, but increased the voltage, 3 1.5v batteries vrs 2, then we could be seeing a better SPOT messenger device.

Are y'all referring to your experience with the new SPOT Satellite GPS Messenger? It's only been out a few weeks or so....
Wastral's diversion brought us to the old SPOT, since his experiences were over a year ago, and I purchased mine 1.5 years or so back. The initial part of the conversation dealt more with the differences between a SPOT and avy beacon (e.g. the latter uses a longer lambda). The new SPOT uses the same wavelength as the old SPOT, but may have better reception and stronger transmission. The new unit requires 3 Li AAA, whereas the old one required 2 Li AA. The new unit seems like it may have decreased battery life; I don't know if that is because the battery power is less, or because the transmission power is greater.
