But what is Sarloc?
It's a web based service for getting the location of a misper. This article is rather interesting:
https://www.ukclimbing.com/articles/skills/using_sarloc_for_rescue_on_your_smartphone-10917"The rescue team simply sends an SMS text message with a link to a webpage. Clicking on this link opens a page in the phone's browser which queries the phone to identify its location. This data is then displayed to the user and automatically added over the internet to the MRMap database. So, whoever it is back at base with the kettle, handling the call-out, can see the casualty's location on the digital OS map display. And, more importantly, he or she can now instruct team members exactly which direction to head in."
Not universally rolled out, looks like it's a SAR/MRT specific, which is fine if you have actually got through the first few hops to get a LSAR or MRT callout going. But usually by the time you get to that level, if you have comms, then they are pretty good at getting the info from you to find you. The problem is, if you are just talking to the 999 call centre, they are unlikely to have it.
Personally I have an inreach+ tracker. If I'm really in the shit, I'll hit the magic button and await help. It sends my position via satellite to a control desk, who notifies the correct people where ever I am, works world wide (except a couple of war zones, where it works, just noone will come for me), no issues with phone signal (and before everyone says "but GSM is pretty good now" check your privilege and go cycle 10km outside of a German town...), no issues with having to work out my position and relay it to someone.
What3words has a place, I think it's a great idea, tho I understand some peoples scepticism.
