This is an impressive product which offers real advantage over its competitors such as the Spot as, combined with a smart phone, it allows for two way communication by text to a nominated third party. For marine use, this is especially useful as it provides a crucial level of emergency alarm BELOW that of an out and out SOS for lesser emergencies such as an engine breakdown where the exact nature of the emergency (as well as the precise location of the unit when sent)can be communicated by text or email to someone on the phones address list. It also allows a third party with access to a computer to track the location of the device every ten minutes.

I've had my Delorme for quite a while now. It's used primarily for tracking a glider, though we have used it for tracking runs and walks as well. So far it has performed very well - track reliability is much higher than the Spots, and it's really helpful getting altitude, speed and direction information. Pairing with an iPhone works well and I haven't had any trouble sending or receiving messages.
Delorme support is superb. I have contacted them about a few minor issues (website), they were quick to respond and confirm the issue. The website is easy to use, though admittedly a bit slow in the UK - everything is hosted in the US (easy to get used to google maps and how fast it is). This seems to have got better recently.
