If what I read is true the Delorme requires a $20 activation and a monthly subscription of between $10 and $50 a month. If you can use it as a pure PLB without a payment each month that would be pretty good, but I personally don't care for the monthly payments.
I have a ResQLink PLB that has no cost associated with it other than the initial purchase price which is about the same as the Delorme. Also fits in a Fast Find canister. Looks like the Delorme has a few extra features such as messaging where ResQLinks are pure PLBs, and maybe that's why the Delorme has a monthly subscription plan?
Correct. The Delorme uses Iridium, a network of 50+ LEO satellites. The Department of Defense is one of the biggest users of this network and it is has truly global coverage (technically there are a few small holes but you won't dive North Korea so that's not a big issue).
The Delorme Inreach can be used on land when hiking/biking/skiing/driving in non-emergency situations and for general tracking as well as having the SOS function. Devices such as the Resqlink need to be registered with your coast guard or other government agencies.
Not an option for someone in Thailand who isn't a Thai citizen. Neither an option in the Philipines and and and (the list goes on... you get the idea.).
For example: In Thailand all PLB are under the jurisdiction of the department of civil aviation and they will never, ever deal with a non-Thai citizen to register a PLB to take out on a dive boat.
If I were to activate my Resqlink somewhere off the coast of Burma, would anyone give a hoot ? If I were an American resident and I had to activate an American-registered PLB off the coast of Indonesia, would there be local infrastructure and resources in place to facilitate a rescue ?
Would I have visual confirmation that my SOS has been received and rescue efforts are under way ? Nope. Hence my comment that for diving in exotic places something like the Delorme Inreach are best. The Inreach is two-way. With the stand-alone unit I will see by the way the SOS light is flashing if my message is sending, has been sent and I will see a positive confirmation once they have processed the message and are initiating rescue. Using it on land in conjunction with a smart-phone they can even ask me questions to get a situation report and mount an even more meaningful rescue. The thing is awesome!
The McMurdo FastFind / ResqLink / Nautilus Lifeline kind of products are great for mostly marine applications in well developed and "civilized countries" with resources. For anyone not fortunate enough to live and dive in such a place, the Delorme Inreach is well worth the fees. I think they have an emergency-only plan that's only 9.95 a month.

BTW I do not work for them
I love the thing to bits so people might wonder if I get paid for these comments
