IMO the best use of tubing in a PSK is to extract water from tight spots that are hard to access: shallow depressions, rock crevices, etc. I know ETS is no fan of the solar still but in the right conditions and with the right methods they can be surprisingly effective, and its nice to access their water via tubing instead of disturbing the still.



Have you researched this? Be careful that your tourniquet fully stops arterial flow. If it stops venous flow and not all arterial flow, you will bleed out faster than if you had not applied the tourniquet.

For improvised tourniquets you are better off with a stick and a rag.
