Some cities have waterfront airports - Toronto being one example. The city was well within visual range. On a recent sailing event, we were far enough out that VHF radio was unable to reach shore and Cell phones were unable to pick up a signal either. In this case, there was no emergency. We were just a little bit late getting back to our destination. This example does show the limitations of our standard communication devices. Since there is a steady flow of traffic out of the city airport, the ability to communicate with a passing aircraft might have proven useful in an emergency. This is also a scenario where SPOT's signal would have clear access to Satellites. **************************** Aviation VHF don't have marine channels, and vice versa. As most paddlers already carry marine handheld VHF, in the above situation they would've had to carry one more handheld - aviation (which at best is splashproof, which in turn means cumbersome designated drypack for this baby). OTH, boaters (those with cabins) may carry all-band dash-mounted transceiver with marine, avia, SSB, etc etc. One more thought has crystallyzed in my mind after this described above situation - that SPOT is a very good device exactly for the above situation - when there is no emergency. To keep family happy, you know... Like , I'm OK, will be home late. When there IS an emergency, I tend to think that 406 PLB with built-in GPS will be more reliable and very likely, faster tool in the USA and Canada - its satellite signal received by the ground station is transmitted directly to mission control centre, 24/7. Please correct me anybody who knows better this anatomy: SPOT distress call from the main SPOT hub (I forgot where exactly it is), will be re-transmitted to local 911 dispatch centre - or to Coast Guard? Or both? I have a gut feeling that local police, receiving a call from 911 dispatch center, will not jump in Zodiacs or choppers and rush to my rescue, - they normally don't do that. They will have to relay the message to the Coast Guard instead. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
