What to check
Download appropriate navigation resources, plan the route and share your expected return with a trusted person. Consider battery reserves and weather protection. A consumer location tracker should not be treated as an emergency beacon or a staffed rescue service.
Before you rely on it
For remote trips, research equipment designed for emergency communication in that region and follow local guidance. Learn its activation and testing procedure before departure. A map marker is useful information, but it cannot remove the need for preparation, navigation skills and a suitable emergency plan.
