probably off topic, definately getting daft, so moderators please feel free to chop this post, no offence will be taken
what we need for those of us that do not take enough water with them is to club together and build a few of these:-
Take one SART, adapt the trigger mechanism with a 'dead' man alarm circuit, requiring manual reset every 30 minutes, failure to reset will trigger audible alarm for 3 minutes, further failure to reset will trigger SART.
this will then enable PyroDave or similar experienced cache event organiser to set up CITO event to recover remains of cacher for return to his/her immediate family.
Costs for the SART equipment would be recovered by selling dead cachers items on ebay, GPSr, rucksack, clothes, boots, walking stick, ''empty'' water bottle etc.
stay safe people, water is essential....finding the cache is not....
