Camping vs Cryonics

Assuming that a cryonicist a) has a limited budget; b) believes that going solo hiking, canoeing, and camping have salutary effects on mental health; and c) believes that camping provides one of the best available ratios of improved long-term mental functioning to dollars spent...

... then what measures could said cryonicist take to minimize the odds of ending up not just dead, but warm-and-dead? And, secondarily, how much would each such measure cost, and how much would it reduce that risk?

Example 1: A PLB (Personal Locator Beacon) costs around $300, and uses satellites to signal search-and-rescue teams to start looking in roughly an area a mile around. Requires someone alive to push the button, that the PLB can be placed right-side-up. Benefits are increased if, eg, a pen-type flare launcher can more precisely identify location to searchers.

Example 2: A backup cell phone can cost $20, and at least one provider offers service for $10 for the SIM chip and $20 per year if no calls are made. Requires limiting trips to areas within range of cell towers.
