For more than 20 years, I go out alone with my horse (forest, countryside, sea).
This is my 7th horse, all black PRE.
I always have a tracker attached to my saddle that allows me, in case of flight from my horse after a fall, to locate him and catch him up through an application on my iPhone. However, I only have my phone to call for help. I am wearing a GPS watch that indicates my position.
In case I lose consciousness, I have nothing! Hence the interest of your product.
