<< apparently there's about a 15-minute delay between when you can send signals >>

Brian, thanks for that real world information. I relayed it to my husband (he wants the Spot Messenger for his birthday) and he is chewing it over. I suspect he will still ask for it. His initial response was keep the code table limited to 3 taps (45 minutes) which could be sent easily over dinner and later while staring at the stars. Also, it seems to make sense to limit how many codes to pre-plan, maybe 1 - 3 maximum and not try to make the Spot Messenger into a text messenger, which it isn't.

I'm with you on the bluetooth keyboard that I could dual use with both SPOT and my smartphone ... ! Carol
