GPS - FindMeSpot

[sanssouci]

Does this really work international?
Can you track on the internet across the Pacific?
How much does it cost?

It works in most places around the world within several hundred miles of the coast . . . except not in the mid-Pacific or Indian Ocean or the Southern Ocean.

Go to http://findmespot.com/en/ and click on "Spot Overview," then "Coverage Map."

Look at skymate too
SkyMate. Wherever you are. Whatever you need.

If you want to have some sort of tracking across the Pacific, check out these two units:

Solara Field Tracker 2100 (costs around US$ 800, and the service plan is $30 per month).
Field Tracker 2100 - Solara Remote Data Delivery
It uses the Iridium network of satellites, as opposed to the Globalstar birds used by Spot. Includes two-way emergency texting, along with GPS fixes. I haven't heard much about these in use.

Also ACR has a new PLB with an "OK" function (trying to compete with Spot). It's the Aqualink 2884. (Costs around US$ 400. Not sure what the service plan costs.)
ACR Products
I believe these have a much higher transmit signal strength than the Spot, and (I think) they use the same SARSATs that EPIRBs use. Again, haven't heard much about them in use, but I imagine they are more reliable than Spot in general, and have true global coverage.
