Weight versus value preparedness spectra ideas.
Physical weight may relate to value differently in different survival situations. The value of ultra-light consumables may match up better in a short-term emergency, for example.
As I think about this, my mind wants to classify things to help plan appropriate preparation. I presume wiser heads have already thought this through and I welcome corrections and comments to help me better wrap my head around these concepts.
Possible gear kit weight spectrum:
1. ultra-light - PSK and PFAK, recreational day pack
2. lightweight – BOB, recreational backpack
3. medium weight – car kit
4. heavy weight – survival cache
Possible gear value spectrum:
1. Ultra-low – single use consumable
2. Low – multiple use consumable, or battery dependent
3. Medium – self-powered or high-quality mechanical
4. High – skill-based and replaceable
Possible survival need spectrum:
1. Short-term emergency – almost instant need to take action to preserve and protect self or others, such as first aid.
2. Limited-term emergency – one-dimensional, limited time, limited area problem with need to preserve and protect self or others, such as power loss from a storm
3. Long-term emergency – multi-dimensional, uncertain duration, either a widespread problem with need to preserve and protect self or others, such as power, water, sewer, etc. out due to a major regional hurricane, or to your group without expectation of short-term assistance, such as plane crash deep in the wilderness
4. Permanent emergency – TEOTW-type scenario
