I refute that! LOL At 71 I have carried it and a large heavy tripod to the tops of mountains and the bottom of large sinkholes on my own! But I agree for the average sensible person it's probably not pocketable...
Perhaps a lightweight version is begging to be made... Perhaps from 10mm thick metal instead of 25mm.
