I suppose for those 24 hour marathon hunts it would be perfect though. 
Thanks for the info Jack!
I think I actually went on one of those hunts a couple years ago
It was a DfX Only group hunt at an old Boyscout camp in Ohio (actually where I met quite a few members from here in person

Yazoo, IllDigger, Schrecky, and I think Jeff/Firefighter43?)
It was "hunt till you drop"---- people were out w/headlamps into the night!

But man, were my arms and feet sore after that weekend!
