Hi @ syberiacoin, everything that increases safety is a great product.
Unlimited security does not exist but the time from the incident to the call for aid is most important for the speed of the "rescuers" reaction.
Calling help is the most simple - just a long press of the red button.
By using SAFER PRO app (the persons you're connected to), they can always see your location at any time.

In any case, it is more efficient than calling with a cell phone because the one who gets your message knows what it is all about.
He must read the location, go to the location and invite others to help (the police).
The outcome is as always - uncertain but you have a greater chance, than yes you have not called for help.

Good luck with hunting.
